In order to enhance the air conditioning effect, the house Bh is desirably an industrialized house having excellent heat insulation performance, light shielding performance, and airtight performance.

  The house Bh includes an underfloor space 3 and an above-floor space 4. The underfloor space 3 is a non-residential space surrounded by the foundation 5, the ground 6 and the floor 7. The floor space 4 is a space provided above the floor space 3. The floor space 4 of the present embodiment is divided into a plurality of living rooms 4A to 4D and non-living rooms (not shown) such as washrooms and toilets.

The target temperature is a temperature that is desired to be maintained in each of the living rooms 4A to 4D by heating by the air conditioner 16. The target temperature can be set as appropriate. The target temperature of the present embodiment is preferably set to, for example, 18 ° C. to 22 ° C. (20 ° C. in the present embodiment) from the viewpoint of preventing heat shock. The target temperature may be set for each of the living rooms 4A to 4D, or may be the same. The target temperature is stored in the storage unit 34 and is read into the work memory 35.

  Next, in heating mode S23, the temperature of each room 4A thru | or 4D is detected (step S231). As shown in FIGS. 1 and 3, the temperatures of the living rooms 4 </ b> A to 4 </ b> D are detected by the living room temperature detection means 25 (25 a to 25 d), respectively. The temperature of each room 4A to 4D is transmitted to the control means 26.

  Next, in the heating mode S23, values W1 obtained by subtracting a predetermined target temperature from the temperatures of the living rooms 4A to 4D are respectively obtained (step S232). The value W1 is obtained for each of the living rooms 4A to 4D. It shows that the temperature of each room 4A thru | or 4D is so large that the value W1 is large.

  Next, in the heating mode S23, it is determined whether or not the value W1 of all the living rooms 4A to 4D is equal to or greater than a predetermined second heating threshold (step S233). In step S233, it is determined whether air conditioning (heating) by the air conditioner 16 is necessary. Therefore, it is desirable that the second heating threshold is set to 0 ° C. or higher. The 2nd heating threshold value of this embodiment is set as +1.5 ° C larger than 0 ° C, for example.

  When it is determined that the values W1 of all the living rooms 4A to 4D are equal to or higher than a predetermined second heating threshold (for example, + 1.5 ° C.) (“Y” in step S233), all the living rooms 4A The temperature of 4 to 4D is higher than the target temperature (for example, 20 ° C.). For this reason, all the living rooms 4A to 4D are sufficiently warmed, and it can be determined that air conditioning (heating) by the air conditioner 16 is unnecessary. In such a case, the next air conditioning stop step S234 is executed. On the other hand, when it is determined that the value W1 of all the living rooms 4A to 4D is less than a predetermined second heating threshold (for example, + 1.5 ° C.) (“N” in step S233), the living room 4A At least one of the 4D rooms is not sufficiently warmed. For this reason, it can be determined that air conditioning (heating) by the air conditioner 16 is necessary. In such a case, the heating step S235 for supplying the warm air warmed by the air conditioner 16 to each of the living rooms 4A to 4D is executed. Note that the second heating threshold is set to a value smaller than + 1.5 ° C. (for example, + 1.0 ° C.), for example, in order to increase the temperature of each room 4A to 4D and to save energy in the air conditioner 16. It may be set.

FIG. 7 is a flowchart illustrating an example of a processing procedure of the air conditioning stop step S234. In the air conditioning stop step S234 of the present embodiment, first, the operation of the air conditioner 16 (shown in FIG. 1) is stopped (step S611), and the first floor fan 10Ba and the second floor fan 10Bb of the ventilation means 10 shown in FIG. Is set (step S612). The set air volume of the first-floor fan 10Ba and the second-floor fan 10Bb of the present embodiment is set to the first air volume (for example, 87.5 m ³ / h) based on the ventilation frequency required for the building B.

  Further, in the air conditioning stop step S234, as shown in FIGS. 1 and 2, the first space 9A and the second space 9B are blocked by the opening / closing part 9C of the chamber box 9 (step S613). Thereby, similarly to ventilation mode S22, each living room 4A thru | or 4D is ventilated with the clean external air (underfloor air 17). Further, the first space 9A and the second space 9B are shut off, so that heat discharged during maintenance such as automatic cleaning of the filter of the air conditioner 16 is supplied to each of the rooms 4A to 4D in the ventilation mode S22. It is possible to prevent the underfloor air 17 from being affected. By completing the execution of these steps S611 to S613, a series of processes of the air conditioning stop step S234 is completed.

  FIG. 8 is a flowchart illustrating an example of the processing procedure of the heating step S235. In the heating step S235, first, the first space 9A and the second space 9B are communicated by the opening / closing part 9C of the chamber box 9 (step S620). If the first space 9A and the second space 9B are already in communication, step S620 is omitted.

  Next, in heating step S235, heating by the air conditioner 16 (shown in FIG. 1) is started (step S621). In step S621 of the present embodiment, first, the air conditioner 16 is heated. Next, the first floor fan 10Ba and the second floor fan 10Bb of the ventilation means 10 are operated. As a result, in the first space 9A, the air in the underfloor space 3 and the warm air warmed by the air conditioner 16 are mixed. The mixed air (warm air + underfloor air) is supplied to the living rooms 4A to 4D by the ventilation means 10. Thereby, heating (air conditioning) by the air conditioner 16 can be realized while performing ventilation. If heating by the air conditioner 16 has already been started, step S621 is omitted.

  Next, in heating step S235, it is determined whether or not the smallest minimum value W1s among the values W1 of the living rooms 4A to 4D is equal to or less than a predetermined third heating threshold (step S622). . In step S622, it is determined whether more aggressive operation of the air conditioner 16 (shown in FIG. 1) is necessary. Therefore, it is desirable that the third heating threshold is set to be less than 0 ° C. The 3rd heating threshold value of this embodiment is set as -0.5 ° C, for example.

  When the minimum value W1s is equal to or lower than the third heating threshold (for example, −0.5 ° C.) (“Y” in step S622), the temperature of at least one room 4A, 4B, 4C, or 4D (shown in FIG. 1) Has fallen. For this reason, the active operation step S623 for performing the active operation of the air conditioner 16 (shown in FIG. 1) is performed. On the other hand, when the minimum value W1s is larger than the third heating threshold value (for example, −0.5 ° C.) (“N” in step S622), the living rooms 4A to 4D are relatively warm. For this reason, the efficient operation step S624 in which the efficient operation of the air conditioner 16 is performed is performed.

  In the active operation step S623, the amount of warm air supplied to each of the living rooms 4A to 4D and the fan 10B (this implementation) for each living room area A (in this embodiment, the first floor living room area A1 and the second floor living room area A2). In the embodiment, the air volume of the first floor fan 10Ba and the second floor fan 10Bb) is adjusted. FIG. 9 is a flowchart illustrating an example of the processing procedure of the active operation step S623 of the present embodiment.

  In the active operation step S623 of the present embodiment, first, the amount of warm air supplied to each room 4A, 4B in the first floor room area A1 and the air volume of the first floor fan 10Ba are adjusted (first floor room area adjustment step). S631). FIG. 10 is a flowchart showing the procedure of the first-floor room area adjustment step S631.

  In the first-floor room area adjustment step S631, first, the largest maximum value W2m among the values W1 of all the rooms included in the first-floor room area A1 (in the present embodiment, the first-floor rooms 4A and 4B) is: It is determined whether it is below a predetermined first heating threshold (step S641). In this step S641, it is determined whether or not heating is required by maximizing the amount of warm air (mixed air) supplied to each room 4A, 4B included in the first floor room area A1. Therefore, it is desirable that the first heating threshold value be set smaller than the third heating threshold value (for example, −0.5 ° C.) used for determining whether or not active operation is necessary. The 1st heating threshold value of this embodiment is set to -1.5 ° C.

  When the maximum value W2m is equal to or less than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S641), all the rooms in the first-floor room area A1 (in the present embodiment, the first-floor rooms) The temperature of 4A, 4B) is greatly reduced. For this reason, the supply amount of warm air (mixed air) to each of the living rooms 4A and 4B in the first-floor room area A1 is set to the maximum (step S642). In this case, the dampers 20a and 20b (shown in FIG. 1) of the respective rooms 4A and 4B in the first-floor room area A1 are set to the largest fifth opening. Thereby, the supply amount of warm air to each living room 4A, 4B of the first floor living room area A1 can be maximized.

  On the other hand, when the maximum value W2m is larger than the first heating threshold (for example, −1.5 ° C.) (“N” in step S641), all the rooms in the first-floor room area A1 (in the present embodiment, the first floor) The temperature of the living rooms 4A, 4B) is not greatly reduced. Therefore, it is effective to individually adjust the amount of warm air (mixed air) supplied to each room 4A, 4B in the first-floor room area A1 to heat the room. In this case, after the next step S643 or step S644 is executed, a room supply amount adjustment step of individually adjusting the amount of warm air supplied to each room 4A, 4B in the first floor room area A1 is performed. The room supply amount adjustment step includes a first room supply amount adjustment step S645 and a second room supply amount adjustment step S646.

  FIG. 11 is a flowchart showing an example of the processing procedure of the first living room supply amount adjustment step S645. FIG. 12 is a flowchart illustrating an example of a processing procedure of the second living room supply amount adjustment step S646. In the first living room supply amount adjustment step S645 and the second living room supply amount adjustment step S646, the first floor living room is based on the value W1 of the first floor living room area A1 (in this embodiment, the first floor living rooms 4A and 4B). The opening degree of the damper 20 (20a, 20b (shown in FIG. 1)) in the room in the area A1 is individually adjusted. In this embodiment, the opening degree of the dampers 20a and 20b is set to be larger in the room 4A or the room 4B where the value W1 is smaller. Thereby, since more warm air (mixed air) is supplied to room 4A, 4B where temperature is low, it can be heated efficiently.

  For each of the first opening to the fifth opening, the threshold range of the value W1 of the rooms 4A and 4B (shown in FIG. 1) of the first floor room area A1 is set. As shown in FIG. 11, the threshold range in the first room supply amount adjustment step S645 is, for example, “greater than + 3.0 ° C.”, “+ 3.0 ° C. (below) to + 1.0 ° C. (from ”+ 1.0 ° C. (below) to −1.0 ° C. (greater than)”, “−1.0 ° C. (below) to −3.0 ° C. (above)”, and “− It is less than 3.0 ° C. On the other hand, as shown in FIG. 12, the threshold range in the second room supply amount adjustment step S646 is “greater than + 1.5 ° C.”, “+ 1.5 ° C. (below) to + 0.5 ° C. Is also + 0.5 ° C. (below) to −0.5 ° C. (greater than) ”,“ −0.5 ° C. (below) to −1.5 ° C. (above) ”,“ −1. Less than 5 ° C. ” Note that the present invention is not limited to such an embodiment.

  As described above, the first room supply amount adjustment step S645 has a larger threshold range than the second room supply amount adjustment step S646. Therefore, even if the value W1 of the living rooms 4A and 4B (shown in FIG. 1) in the first-floor living room area A1 is distributed over a wide range, the first living room supply amount adjustment step S645 performs the damper 20a for each of the living rooms 4A and 4B. , 20b can be adjusted in a well-balanced manner. The details of the first living room supply amount adjustment step S645 and the second living room supply amount adjustment step S646 will be described later.

  As shown in FIG. 10, in step S643, is the smallest minimum value W2s out of the values W1 of the living rooms 4A and 4B (shown in FIG. 1) in the first-floor room area A1 less than or equal to the fourth heating threshold value? It is determined whether or not. If the minimum value W2s is significantly small, there is a high possibility that the values W1 of the living rooms 4A and 4B are distributed over a wide range. Therefore, in order to determine the presence or absence of such a distribution, it is desirable that the fourth heating threshold is set to be smaller than the first heating threshold (for example, −1.5 ° C.). The 4th heating threshold value of this embodiment is set as -3.0 ° C, for example.

  When the minimum value W2s is equal to or lower than the fourth heating threshold (for example, −3.0 ° C.) (“Y” in step S643), the rooms 4A and 4B (shown in FIG. 1) of the first-floor room area A1 There is a high possibility that the value W1 is distributed over a wide range. In this case, the first living room supply amount adjustment step S645 is performed. On the other hand, when the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.), it is determined only in this step S643 whether or not the values W1 of the respective rooms 4A and 4B are distributed over a wide range. Since this is not possible, the next step S644 is performed.

  In the first room supply amount adjustment step S645, as shown in FIG. 11, the dampers 20 (20a or 20b) of each room 4A or room 4B (shown in FIG. 1) in the first-floor room area A1 having the smaller value W1. ) Is set to be large (steps S662 to S666). For example, the smallest first opening degree is set for the damper 20 of the living room 4A or 4B in which the value W1 is greater than + 3.0 ° C. (step S662). The damper 20 of the living room 4A or 4B in which the value W1 is + 3.0 ° C. to + 1.0 ° C. is set to a second opening larger than the first opening (step S663). The damper 20 of the living room 4A or 4B in which the value W1 is + 1.0 ° C. to −1.0 ° C. is set to a third opening larger than the second opening (step S664).

  Furthermore, the damper 20 (20a or 20b) of the room 4A or 4B in which the value W1 is −1.0 ° C. to −3.0 ° C. is set to a fourth opening larger than the third opening (step) S665). The damper 20 of the living room 4A or 4B in which the value W1 is less than −3.0 ° C. is set to a fifth opening that is larger than the fourth opening (step S666).

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in this embodiment, the living rooms 4A and 4B) of the first floor living room area A1 has been adjusted (step S667). When it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 have been adjusted (“Y” in step S667), the series of processes in the first room supply amount adjustment step S645 is completed. To do. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 are not adjusted ("N" in step S667), the other rooms 4A in the first-floor room area A1 Alternatively, the 4B damper 20 is selected (step S668), and steps S661 to S667 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B of the first floor living room area A1 is adjusted based on the value W1, supply of warm air (mixed air) to the respective living rooms 4A and 4B The amount can be adjusted individually.

  In this embodiment, the opening degree of the dampers 20a and 20b is set to be larger in the room 4A or the room 4B where the value W1 is smaller. Accordingly, since the warmer rooms (mixed air) are supplied to the living rooms 4A and 4B having lower temperatures, the living rooms 4A and 4B can be efficiently heated. In addition, about each threshold value which divided | segmented the opening degree of each damper 20 (20a, 20b), it is not necessarily limited to said value, For example, according to the air volume of the fan 10B (1st floor fan 10Ba) of the ventilation means 10. And may be changed as appropriate.

  As shown in FIG. 10, in step S644, it is determined whether or not the maximum value W2m is greater than or equal to the fifth heating threshold. If the maximum value W2m is significantly large, there is a high possibility that the values W1 of the respective rooms 4A and 4B in the first-floor room area A1 are widely distributed. Therefore, in order to determine the presence or absence of such a distribution, it is desirable that the fifth heating threshold value is set to a value larger than the second heating threshold value (for example, + 1.5 ° C.). The 5th heating threshold value of this embodiment is set as +3.0 ° C, for example.

  When the maximum value W2m is greater than or equal to the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S644), the values W1 of the respective rooms 4A and 4B in the first-floor room area A1 are widely distributed. There is a high possibility. In this case, the first room supply amount adjustment step S645 shown in FIG. 10 is performed. On the other hand, when the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S644), the maximum value W2m is relatively small. Moreover, the minimum value W2s is relatively large as determined in step S643. Therefore, it is unlikely that the values W1 of the living rooms 4A and 4B in the first-floor room area A1 are distributed over a wide range. In this case, the second living room supply amount adjustment step S646 is performed.

  In the second room supply amount adjustment step S646, as shown in FIG. 12, as in the first room supply amount adjustment step S645, each room 4A or 4B in the first-floor room area A1 having a smaller value W1 has its damper. The opening degree of 20 (20a or 20b (shown in FIG. 1)) is set to be large (steps S672 to S676). For example, the smallest first opening degree is set for the damper 20 of the living room 4A or 4B in which the value W1 is greater than + 1.5 ° C. (step S672). The damper 20 of the living room 4A or 4B in which the value W1 is + 1.5 ° C. to + 0.5 ° C. is set to a second opening larger than the first opening (step S673). The damper 20 of the living room 4A or 4B having the value W1 of + 0.5 ° C. to −0.5 ° C. is set to a third opening larger than the second opening (step S674).

  Further, the damper 20 (20a or 20b) of the living room 4A or 4B having the value W1 of −0.5 ° C. to −1.5 ° C. is set to a fourth opening larger than the third opening (step). S675). The damper 20 of the living room 4A or 4B in which the value W1 is less than −1.5 ° C. is set to a fifth opening that is larger than the fourth opening (step S676).

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in this embodiment, the living rooms 4A and 4B) of the first floor living room area A1 has been adjusted (step S677). When it is determined that the openings of the dampers 20 in all the living rooms 4A and 4B have been adjusted (“Y” in step S677), the series of processes in the second living room supply amount adjusting step S646 ends. On the other hand, when it is determined that the openings of the dampers 20 in all the living rooms 4A and 4B are not adjusted (“N” in step S677), the dampers 20 in the other living rooms 4A or 4B are selected (step S678). Steps S671 to S677 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B of the first floor living room area A1 is adjusted based on the value W1, supply of warm air (mixed air) to the respective living rooms 4A and 4B The amount can be adjusted individually.

  In this embodiment, the opening degree of the dampers 20a and 20b is set to be larger in the room 4A or the room 4B where the value W1 is smaller. Thereby, since more warm air (mixed air) is supplied to the living rooms 4A and 4B having lower temperatures, the living rooms 4A and 4B can be efficiently heated. In addition, about each threshold value which divided the opening degree of each damper 20 (20a and 20b), it is not necessarily limited to said value.

  Next, in the first-floor room area adjustment step S631 of the present embodiment, as shown in FIG. 10, the air volume of the fan 10B (first-floor fan 10Ba) in the first-floor room area A1 is adjusted (fan air volume adjustment step S647). ~ S650). In the fan air volume adjustment steps S647 to S650, the air volume of the first-floor fan 10Ba is adjusted based on the value W1 (the value obtained by subtracting the target temperature from the temperature of the room 4A or 4B in the first-floor room area A1).

In step S641, when it is determined that the maximum value W2m of the value W1 of the first-floor room area A1 is equal to or less than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S641), the minimum The value W2s may be significantly smaller than the first heating threshold. For this reason, it is effective to increase the air volume of the first-floor fan 10Ba and to actively supply warm air to the first-floor room area A1 including the low-temperature room 4A or 4B. Accordingly, the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S647).

Similarly, when it is determined in step S643 that the minimum value W2s of the first-floor room area A1 is equal to or lower than the fourth heating threshold value (for example, −3.0 ° C.) (“Y” in step S643), The air volume of the first floor fan 10Ba is set to a fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S648).

In step S644, when it is determined that the maximum value W2m of the first-floor room area A1 is equal to or greater than the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S644), the fan air volume adjustment step S647 and It can be determined that it is not necessary to increase the air volume of the first-floor fan 10Ba at S648. For this reason, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S649).

In step S644, when it is determined that the maximum value W2m of the first-floor room area A1 is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S644), the fan air volume adjustment step S647 and Although it is not necessary to increase the air volume of the first floor fan 10Ba as in S648, it is effective to increase the air volume of the first floor fan 10Ba rather than the fan air volume adjustment step S649. For this reason, the air volume of the first floor fan 10Ba is set to the third air volume (for example, 400 m ³ / h) (fan air volume adjustment step S650).

  In this way, in the fan air volume adjustment steps S647 to S650, the air volume of the first-floor fan 10Ba is set to be larger as the minimum value W2s of the first-floor room area A1 is smaller. Further, the larger the maximum value W2m of the first floor room area A1, the smaller the air volume of the first floor fan 10Ba. Accordingly, the rooms 4A and 4B in the first floor room area A1 can be efficiently heated. After the process of the fan air volume adjustment steps S647 to S650 is completed, a series of processes of the first-floor room area adjustment step S631 is completed.

  Next, as shown in FIG. 9, in the active operation step S623, the supply amount of warm air to the respective rooms 4C and 4D in the second-floor room area A2 and the air volume of the second-floor fan 10Bb are adjusted (2 Floor room area adjustment step S632). FIG. 13 is a flowchart showing the processing procedure of the second-floor room area adjustment step S632.

  In the second-floor room area adjustment step S632, first, the largest maximum value W3m among the values W1 of all the rooms included in the second-floor room area A2 (in this embodiment, the second-floor rooms 4C and 4D) It is determined whether it is below a predetermined first heating threshold (step S651). The first heating threshold is set to −1.5 ° C. as in the first-floor room area adjustment step S631.

  When the maximum value W3m is equal to or less than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S651), all the rooms in the second-floor room area A2 (in the present embodiment, the second-floor rooms) Since the temperature of 4C, 4D) is greatly reduced, the supply amount of warm air (mixed air) to each of the living rooms 4C, 4D in the second-floor room area A2 is set to the maximum (step S652). In this case, the dampers 20c and 20d (shown in FIG. 1) of the respective rooms 4C and 4D in the second-floor room area A2 are set to the largest fifth opening.

  On the other hand, when the maximum value W3m is larger than the first heating threshold (for example, −1.5 ° C.) (“N” in step S651), the temperatures of all the rooms 4C and 4D in the second-floor room area A2 are large. Since it is not reduced, it is effective to individually adjust the amount of warm air (mixed air) supplied to the living rooms 4C and 4D in the second-floor room area A2 to heat the rooms. Accordingly, similarly to the first floor living room area adjustment step S631, the first living room supply amount adjustment step S655 and the second living room supply amount adjustment step S656 are performed.

  Next, in the second-floor room area adjustment step S632, is the smallest minimum value W3s of the values W1 of the respective rooms 4C and 4D (shown in FIG. 1) of the second-floor room area A2 equal to or less than the fourth heating threshold value? It is determined whether or not (step S653). The 4th heating threshold value of this embodiment is set to -3.0 degreeC similarly to 1st floor room area adjustment step S631.

  When the minimum value W3s is equal to or lower than the fourth heating threshold (for example, −3.0 ° C.) (“Y” in step S653), the room 4C, 4D (shown in FIG. 1) of the second-floor room area A2 There is a high possibility that the value W1 is distributed over a wide range. In this case, the first living room supply amount adjustment step S655 is performed. On the other hand, when the minimum value W3s is larger than the fourth heating threshold (for example, −3.0 ° C.), it is determined only in this step S653 whether or not the values W1 of the respective rooms 4C and 4D are distributed over a wide range. Since this is not possible, the next step S654 is performed.

  The first living room supply amount adjustment step S655 is the same processing procedure as the first living room supply amount adjustment step S645 (shown in FIG. 11) of the first floor living room area adjustment step S631. Therefore, since the opening degree of the damper 20 of each living room 4C and 4D in the second floor living room area A2 is adjusted based on the value W1, the amount of warm air (mixed air) supplied to each living room 4C and 4D is Can be adjusted individually. Accordingly, the living rooms 4C and 4D can be efficiently heated.

  As shown in FIG. 13, in step S654, it is determined whether or not the maximum value W3m is equal to or greater than the fifth heating threshold. The fifth heating threshold of the present embodiment is set to + 3.0 ° C., for example, similarly to the first floor room area adjustment step S631.

  When the maximum value W3m is equal to or greater than the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S654), the values W1 of the respective rooms 4C and 4D in the second-floor room area A2 are widely distributed. Therefore, the first living room supply amount adjustment step S655 is performed. On the other hand, when the maximum value W2m is less than the fifth heating threshold (for example, “+ 3.0 ° C.”) (“N” in step S654), the values W1 of the respective rooms 4C and 4D in the second-floor room area A2 are in a wide range. Less likely to be distributed. In this case, the second living room supply amount adjustment step S656 is performed.

  The second living room supply amount adjustment step S656 is the same processing procedure as the second living room supply amount adjustment step S646 (shown in FIG. 12) of the first floor living room area adjustment step S631. In the second room supply amount adjustment step S656, the threshold range is set smaller than that in the first room supply amount adjustment step S655. For this reason, even if the values W1 of the respective rooms 4C and 4D (shown in FIG. 1) in the second-floor room area A2 are not distributed over a wide range, the opening degree of the dampers 20c and 20d is determined for each of the rooms 4C and 4D. It can be adjusted more finely and well-balanced. Therefore, since the supply amount of warm air (mixed air) to each of the living rooms 4C and 4D is adjusted individually, it can be efficiently heated.

  As shown in FIG. 13, in the second-floor room area adjustment step S632 of the present embodiment, the air volume of the fan 10B (second-floor fan 10Bb) in the second-floor room area A2 is adjusted (fan air volume adjustment steps S657 to S660). . In the fan air volume adjustment steps S657 to S660, the air volume of the second-floor fan 10Bb is adjusted based on the values W1 of the respective rooms 4C and 4D in the second-floor room area A2. The fan air volume adjustment steps S657 to S660 are the same processing procedure as the fan air volume adjustment steps S647 to S650 of the first-floor room area adjustment step S631 shown in FIG.

  Accordingly, in the fan air volume adjustment steps S657 to S660, the air volume of the second-floor fan 10Bb is set larger as the minimum value W3s of the value W1 in the second-floor room area A2 is smaller. Further, the larger the maximum value W3m of the second-floor room area A2, the smaller the air volume of the second-floor fan 10Bb. Accordingly, the living rooms 4C and 4D in the second floor living room area A2 can be efficiently heated. After the process of the fan air volume adjustment steps S657 to S660 is completed, a series of processes of the second-floor room area adjustment step S632 is completed.

  As described above, in the present embodiment, the fan air volume adjustment steps S647 to S650 (shown in FIG. 10) in the first-floor room area adjustment step S631 and the fan air volume adjustment steps S657 to S660 in the second-floor room area adjustment step S632 are performed. The air volume of the first-floor fan 10Ba or the second-floor fan 10Bb is adjusted for each of the room areas A1 and A2 in which the room temperature tends to vary throughout the day. Thereby, since warm air can be positively supplied by the first floor fan 10Ba or the second floor fan 10Bb to the room area A1 or A2 including the low temperature room where the value W1 is relatively small, each room is efficiently heated. Can be done.

  Next, as shown in FIG. 9, in the active operation step S623, prior to the air conditioning temperature adjustment steps S634 and S635 for adjusting the set temperature of the next air conditioner 16, the value W1 of each of the rooms 4A to 4D is set. Among these, whether the smallest minimum value W1s is a fourth heating threshold value (for example, −3.0 ° C.) or less, or whether the largest maximum value W1m is a first heating threshold value (for example, −1.5 ° C.) or less. Is determined (step S633). In this step S633, it is determined whether or not the set temperature of the air conditioner 16 needs to be significantly increased.

  When the minimum value W1s is the fourth heating threshold value (for example, −3.0 ° C.) or less, or the maximum value W1m is the first heating threshold value (for example, −1.5 ° C.) or less (“Y” in step S633). ), The temperature of at least one living room (in this embodiment, the living room 4A, 4B, 4C, or 4D) is greatly reduced. For this reason, the set temperature of the air conditioner 16 is set to the sum of the target temperature (for example, 20 ° C.) and the first additional temperature (air conditioning temperature adjustment step S634). About 1st addition temperature, it can set suitably. The first addition temperature of the present embodiment is set to + 5 ° C., for example.

  On the other hand, when the minimum value W1s is larger than the fourth heating threshold value (for example, −3.0 ° C.) and the maximum value W1m is larger than the first heating threshold value (for example, −1.5 ° C.) (step S633). Therefore, the temperature of all the rooms (in the present embodiment, the rooms 4A to 4D) is not lowered. For this reason, it can be determined that it is not necessary to increase the set temperature of the air conditioner 16 as much as step S634. Accordingly, the set temperature of the air conditioner 16 is set to the sum of the target temperature (for example, 20 ° C.) and the second added temperature (air conditioning temperature adjustment step S635). About 2nd addition temperature, if it is smaller than 1st addition temperature, it can set suitably. The second addition temperature of the present embodiment is set to + 2 ° C., for example. In this way, in the air conditioning temperature adjustment steps S634 and S635, the set temperature is increased as the minimum value W1s (and the maximum value W1m) is decreased, and thus the respective rooms 4A to 4D can be effectively heated.

Next, in the active operation step S623 of the present embodiment, the set air volume of the air conditioner 16 is adjusted (step S636). In the present embodiment, the set air volume of the air conditioner is adjusted based on the total air volume of the fans 10B (in the present embodiment, the first floor fan 10Ba and the second floor fan 10Bb) provided in the living room areas A1 and A2. . The set air volume Fw of the air conditioner 16 of this embodiment is defined by the following formula (1).
Fw = Tf−Vf (1)
Here, each variable is as follows.
Tf: Total fan airflow Vf: Ventilation airflow required for building B

  In the above formula (1), the total air volume Tf of the fan 10B of the present embodiment is set in the air volume of the first-floor fan 10Ba set in the fan air volume adjustment steps S647 to S650 and in the fan air volume adjustment steps S657 to S660. This is the sum of the air volume of the second-floor fan 10Bb.

  The set air volume Fw of the air conditioner 16 is a value obtained by subtracting the ventilation air volume Vf necessary for the building B from the total air volume Tf of the fan 10B (in this embodiment, the first floor fan 10Ba and the second floor fan 10Bb). Of the above-described air volumes (silent air volume to fourth air-conditioning air volume) of the air conditioner 16, an air volume that is closest to the set air volume Fw is set.

  In the above formula (1), the larger the total air volume Tf of the fan 10B (in the present embodiment, the first floor fan 10Ba and the second floor fan 10Bb), the larger the set air volume Fw of the air conditioner 16 is set. Thereby, the warm air warmed by the air conditioner 16 can be effectively supplied to each room (in the present embodiment, the rooms 4A to 4D). Further, the set air volume Fw is set to a value obtained by subtracting the ventilation air volume Vf necessary for the building B from the total air volume Tf, so that the underfloor air 17 necessary for ventilation is also used together with the warm air warmed by the air conditioner 16. , Each living room (in this embodiment, the living rooms 4A to 4D) can be supplied. In this embodiment, after the process of step S636 is completed, a series of processes of the active operation step S623 and the heating step S235 (shown in FIG. 8) is completed.

  FIG. 14 is a flowchart illustrating an example of a processing procedure of the efficient operation step S624 of the present embodiment. As described above, in the efficient operation step S624, the air conditioner 16 is efficiently operated. In the efficiency operation step S624, first, the first space 9A and the second space 9B are communicated with each other by the opening / closing part 9C of the chamber box 9 (step S680). If the first space 9A and the second space 9B are already in communication, step S620 is omitted.

Next, in the efficiency operation step S624, the current heating capacity of the air conditioner 16 is calculated (step S681). In heating mode S23 of this embodiment, the heating capability Ew of the air conditioner 16 is calculated | required by following formula (2).
Ew = (Tb−Ta) × Af × Hs / 1000 (2)
Here, each constant and variable are as follows.
Tb: Temperature of exhaust section of air conditioner (° C)
Ta: Temperature of the air intake unit of the air conditioner (℃)
Af: Air flow rate of air conditioner (m ³ / h)
Hs: Specific heat of air (0.35 Wh / m ³ · ° C)

  The temperature Tb of the exhaust part 16b is measured by the exhaust temperature detection means 28 (shown in FIG. 2). The temperature Ta of the intake section 16a is measured by the intake temperature detecting means 27 (shown in FIG. 2). The air volume of the air conditioner 16 can be acquired by a signal to which the operating status of the air conditioner 16 is transmitted.

  FIG. 15A is a graph showing the relationship among COP (Coefficient of Performance), sensible heat load (kW), heating power consumption (kW), and heating capacity (kW). Generally, when the heating capacity Ew is 2 kW or more, the heating efficiency is poor. In such a case, it is desirable that the air conditioner 16 is operated, for example, by reducing the set temperature and the set air volume so that the heating capacity Ew approaches 2 kW.

  Next, in the efficiency operation step S624, as shown in FIG. 14, it is determined whether or not the current heating efficiency of the air conditioner 16 is poor (step S682). In this embodiment, when the current heating capacity Ew is 2 kW or more, it is determined that the heating efficiency is poor. Thus, when it is judged that heating efficiency is bad, the efficient driving | operation of the air conditioner 16 is performed.

  If it is determined that the heating efficiency of the current air conditioner 16 is poor (the heating capacity Ew is 2 kW or more) (“Y” in step S682), the following is performed before the efficient operation of the air conditioner 16 is performed. Step S683 of FIG. On the other hand, if it is determined that the current heating efficiency of the air conditioner 16 is not bad (the heating capacity Ew is less than 2 kW) (“N” in step S682), the air conditioner 16 has already been efficiently operated. It has been broken. For this reason, a series of the efficiency operation step S624 and the heating step S235 (shown in FIG. 8) while the current operation state (set temperature and set air volume) of the air conditioner 16 and the air volume of the fan 10B are maintained. This process ends.

In step S683, it is determined whether or not the set temperature of the air conditioner 16 is higher than a target temperature (for example, 20 ° C.). When the set temperature of the air conditioner 16 is higher than the target temperature (“Y” in step S683), the living rooms 4A to 4D can be heated to the target temperature even if the set temperature is slightly reduced. In such a case, while the opening degree of the dampers 20a to 20d is maintained (step S684), the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) is set to the third air volume (for example, 400 m ³ / h). The temperature is set (step S685), and the set temperature of the air conditioner 16 is further reduced (step S686). Note that the amount of decrease in the set temperature of the air conditioner 16 is set as appropriate. The decrease in this embodiment is set to −1.0 ° C., for example.

Further, the set air volume of the air conditioner 16 is set to the second air conditioning air volume (for example, 625 m ³ / h) based on the set air volume Fw defined by the above formula (1) (step S687). Thus, in the efficient operation step S624, even if the set temperature of the air conditioner 16 is reduced, the living rooms 4A to 4D are efficiently heated, so that the heating efficiency can be increased.

In addition, when the set temperature of the air conditioner 16 is equal to or lower than the target temperature (“N” in step S683), each room 4A, 4B, 4C, or 4D can be maintained at the target temperature by reducing the set temperature further. There is a risk of disappearing. In such a case, while the opening degree of the dampers 20a to 20d is maintained (step S688), the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) is the first air volume (for example, 87.5 m ³ / h). (Step S689), and the set temperature of the air conditioner 16 is maintained at the target temperature (step S690).

Further, the set air volume of the air conditioner 16 is set to a silent air volume (for example, 325 m ³ / h) based on the set air volume Fw defined by the above formula (1) (step S691). Thereby, in efficient operation step S624, each living room 4A thru | or 4D can be heated efficiently, preventing the deterioration of the heating efficiency of the air conditioner 16. FIG.

  Next, in the efficiency operation step S624, the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) set in steps S684 to S691 are maintained. Thus, the operation of the air conditioner 16 and the fan 10B is left (step S692). Thereby, each room 4A thru | or 4D can be heated efficiently, preventing the deterioration of the heating efficiency of the air conditioner 16. FIG. The remaining time can be set as appropriate. In the present embodiment, it is considered that each living room 4A, 4B, 4C, or 4D is efficiently heated by the set temperature, the set air volume, and the air volume of the fan 10B set in the efficiency operation step S624. For example, it is desirable to set it to about 5 minutes. After the process of step S692, the series of processes of the efficiency operation step S624 and the heating step S235 (shown in FIG. 8) is completed.

  Next, as shown in FIG. 6, in the heating mode S23, it is determined whether or not a predetermined end time has elapsed since the heating mode S23 was started (step S236). The end time can be set as appropriate. In the present embodiment, considering that each living room 4A, 4B, 4C, or 4D is effectively heated by the set temperature, the set air volume, and the air volume of the fan 10B set in the heating mode S23. For example, it is desirable to set it to about 30 minutes, for example.

  When it is determined that the end time has elapsed ("Y" in step S236), the series of processes in the heating mode S23 ends. On the other hand, when it is determined that the end time has not elapsed ("N" in step S236), steps S230 to S236 are performed again. Thereby, in heating mode S23, based on the temperature of each living room 4A thru | or 4D which changes every moment, the opening degree of the damper 20, the preset temperature of the air conditioner 16, the preset air volume, and the fan 10B (first floor fan 10Ba) Since the air volume of the second floor fan 10Bb) is adjusted, each of the living rooms 4A to 4D can be effectively heated.

  Next, in the passive heating mode S24, the underfloor air 17 (shown in FIG. 1) is supplied to each of the rooms 4A to 4D, whereby the rooms 4A to 4D are air-conditioned while being ventilated. FIG. 16 is a flowchart illustrating an example of a processing procedure in the passive heating mode S24. A series of processes in the passive heating mode S24 is performed by the control means 26 (shown in FIG. 3).

  In the passive heating mode S24, first, as shown in FIGS. 1 and 3, the temperatures of the respective rooms 4A to 4D are detected (step S241). The temperature of each room 4A to 4D is detected by the room temperature detection means 25, respectively. The temperature of each room 4A to 4D is transmitted to the control means 26.

  Next, in the passive heating mode S24, the temperature of the outside air is detected (step S242). The temperature of the outside air is detected by the outside air temperature detecting means 24. The temperature of the outside air is transmitted to the control means 26.

  Next, in the passive heating mode S24, the temperature of the underfloor air 17 is detected (step S243). The temperature of the underfloor air 17 is detected by the underfloor temperature detecting means 23. The temperature of the underfloor air 17 is transmitted to the control means 26.

  Next, in the passive heating mode S24, it is determined whether or not the temperature of each of the rooms 4A to 4D is higher than the temperature at which the heating operation by the air conditioner 16 is required (step S244). The “temperature at which the heating operation by the air conditioner 16 is required” can be appropriately set according to, for example, the structure of the building B and the heating capacity (temperature) by the underfloor air 17. In this embodiment, for example, the temperature is set to about 15 ° C.

  When the temperature of each of the living rooms 4A to 4D is higher than the temperature (for example, 15 ° C.) at which heating operation by the air conditioner 16 is required (“Y” in step S244), heating is performed using the underfloor air 17. It can be determined that (air conditioning) is possible. In such a case, the next step S245 is performed. On the other hand, when the temperature of each of the rooms 4A to 4D is equal to or lower than the temperature (for example, 15 ° C.) at which heating operation by the air conditioner 16 is required (in step S244, “N”), the underfloor air 17 is used. However, it can be determined that the living rooms 4A to 4D cannot be sufficiently heated. In such a case, the passive heating mode S24 is interrupted, and the heating mode S23 (shown in FIGS. 5 and 6) is performed.

  Next, in the passive heating mode S24, it is determined whether the temperature of the outside air is equal to or higher than a predetermined temperature (step S245). The “predetermined temperature” of the outside air can be appropriately set according to, for example, the structure of the building B, the heating capacity (temperature) by the underfloor air 17, and the like. In this embodiment, for example, the temperature is set to 10 ° C.

  When the temperature of the outside air is equal to or higher than a predetermined temperature (for example, 10 ° C.) (“Y” in step S245), the influence of the temperature drop of the living rooms 4A to 4D due to the outside air is small, so the underfloor air 17 is used. Thus, it can be determined that the living rooms 4A to 4D can be heated (air-conditioned). In such a case, the next step S246 is performed. On the other hand, when the temperature of the outside air is lower than a predetermined temperature (for example, 10 ° C.) (“N” in step S245), the living rooms 4A to 4D are sufficiently heated even if the underfloor air 17 is used. It can be judged that it is not possible. In such a case, the passive heating mode S24 is interrupted, and the heating mode S23 (shown in FIGS. 5 and 6) is performed.

  Next, in the passive heating mode S24, it is determined whether or not the temperature of the underfloor air 17 is equal to or higher than a predetermined temperature (step S246). The “predetermined temperature” of the underfloor air 17 can be appropriately set according to the structure of the building B, for example. In this embodiment, for example, the temperature is set to 18 ° C.

  When the temperature of the underfloor air 17 is equal to or higher than a predetermined temperature (for example, 18 ° C.) (“Y” in step S246), the living rooms 4A to 4D are used by using the underfloor air 17 having a relatively high temperature. Can be determined to be capable of heating (air conditioning). In such a case, the next first supply step S247 is performed. On the other hand, when the temperature of the underfloor air 17 is lower than a predetermined temperature (for example, 18 ° C.) (“N” in step S246), the use of the underfloor air 17 is effective for each of the rooms 4A to 4D. It can be judged that it cannot be heated automatically. In such a case, the passive heating mode S24 is interrupted, and the heating mode S23 (shown in FIGS. 5 and 6) is performed.

  Next, in the passive heating mode S24, the underfloor air 17 is supplied to the living rooms 4A to 4D (first supply step S247). In the first supply step S247, the temperature of each of the living rooms 4A to 4D is higher than the temperature at which the heating operation by the air conditioner 16 is required, and the temperature of the outside air is determined in advance according to the determination in steps S244 to S246. In addition, this is performed only when it is determined that the temperature of the underfloor air 17 is equal to or higher than a predetermined temperature. Accordingly, in the first supply step S247, the temperature of each of the rooms 4A to 4D, the temperature of the outside air, and the temperature of the underfloor air 17 are relatively high, so that the underfloor air 17 is used without using the air conditioner 16. Thus, the living rooms 4A to 4D can be effectively heated (air-conditioned). Therefore, an increase in air conditioning cost due to the air conditioner 16 can be prevented. FIG. 17 is a flowchart illustrating an example of the processing procedure of the first supply step S247.

As shown in FIG. 1, FIG. 2 and FIG. 17, in the first supply step S247 of the present embodiment, first, the air volume (underfloor air 17) of the fan 10B (first floor fan 10Ba and second floor fan 10Bb) of the ventilation means 10 is used. (Total supply amount) is set (step S711). The air volumes of the first-floor fan 10Ba and the second-floor fan 10Bb of the present embodiment are set to a relatively small second air volume (250 m ³ / h), for example, in consideration of the natural ventilation in winter. In step S711, the first space 9A and the second space 9B are blocked by the opening / closing part 9C of the chamber box 9. As a result, the air in the first space 9A of the chamber box 9 is purified from the exhaust port 14 via the duct 10A and the air purifying device 10C, and then each room 4A via the damper 20 (20a to 20d). To 4D.

  Next, in the first supply step S247, a difference Va between the temperature of each of the rooms 4A to 4D and a predetermined target temperature is obtained (step S712). The target temperature of the present embodiment is desirably set to 20 ° C., for example, from the viewpoint of preventing heat shock. The target temperature may be set for each of the living rooms 4A to 4D. The target temperature is stored in the storage unit 34 in advance.

  The difference Va is obtained for each of the living rooms 4A to 4D. Difference Va of this embodiment is calculated | required as a value which deducted target temperature from the temperature of each living room 4A thru | or 4D similarly to the value W1 of heating mode S23. The larger this value (difference Va), the higher the temperature of each room 4A to 4D.

  In the present embodiment, the temperature (18 ° C.) of the underfloor air 17 determined in step S246 is set to be lower than the target temperature (20 ° C.). For this reason, even if the underfloor air 17 is used, it is considered that each of the rooms 4A to 4D cannot be heated to the target temperature. However, since each of the living rooms 4A to 4D of the present embodiment has internal heat generation by home appliances, residents, etc., even if the underfloor air 17 that is slightly lower than the target temperature is used, the respective living rooms 4A to 4D are targeted. It can be warmed up sufficiently to the temperature. Thus, even if the temperature of the underfloor air 17 is lower than the target temperature, the air conditioning cost can be suppressed because the passive heating mode S24 that does not use the air conditioner 16 is performed.

  Next, in 1st supply step S247, the opening degree of the damper 20 (20a-20d) of each living room 4A thru | or 4D is adjusted based on the said difference Va of each living room 4A thru | or 4D (step S713-step S719). . In the present embodiment, the opening degree of the damper 20 (the supply amount of the underfloor air 17) is set to be larger in the room 4A, 4B, 4C, or 4D where the difference Va is smaller. Thereby, since the warmer underfloor air 17 is supplied to the living rooms 4A to 4D having a lower temperature, each of the living rooms 4A to 4D can be efficiently heated.

  For example, the smallest first opening is set for the damper 20 (20a to 20d) of the room 4A, 4B, 4C, or 4D where the difference Va is greater than + 1.5 ° C. (step S714). The damper 20 of the living room 4A, 4B, 4C, or 4D in which the difference Va is + 1.5 ° C. (below) to + 0.5 ° C. (greater than) is set to a second opening larger than the first opening. (Step S715). The damper 20 of the living room 4A, 4B, 4C, or 4D in which the difference Va is + 0.5 ° C. (below) to −0.5 ° C. (greater than) is set to a third opening larger than the second opening. (Step S716).

  Furthermore, the damper 20 (20a to 20d) of the living room 4A, 4B, 4C, or 4D in which the difference Va is −0.5 ° C. (below) to −1.5 ° C. (or higher) is larger than the third opening degree. The fourth opening is set (step S717). The damper 20 of the living room 4A, 4B, 4C, or 4D having the difference Va of less than −1.5 ° C. is set to a fifth opening that is larger than the fourth opening (step S718).

  And it is judged whether the opening degree of the damper 20 (20a-20d) of all the living rooms 4A thru | or 4D was adjusted (step S719). When it is determined that the openings of the dampers 20 of all the living rooms 4A to 4D have been adjusted (“Y” in step S719), the next step S248 (shown in FIG. 16) is performed. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A to 4D are not adjusted (“N” in step S719), the dampers 20 of the other living rooms 4A, 4B, 4C, or 4D are selected. (Step S720) and Steps S713 to S719 are performed again. Thereby, the opening degree of the damper 20 of all the living rooms 4A to 4D can be adjusted based on the difference Va. Therefore, the supply amount of the underfloor air 17 to the living rooms 4A to 4D can be individually adjusted.

  In addition, each threshold value (in this embodiment, “+ 1.5 ° C.”, “+ 0.5 ° C.”, “−0.5 ° C.”), which is obtained by dividing each opening degree of the damper 20 (20a to 20d), “−1.5 ° C.”) can be changed as appropriate according to the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) of the ventilation means 10, for example. Moreover, although the aspect which calculates | requires the said difference Va of this embodiment as a value which deducted target temperature from the temperature of each living room 4A thru | or 4D was illustrated, it is not limited to this. For example, the difference Va may be obtained as a value obtained by subtracting the temperature of each room 4A to 4D from the target temperature. In this case, it is desirable that the opening degree of the damper 20 (the supply amount of the underfloor air 17) is set to be larger as the difference Va is larger.

  Next, as shown in FIGS. 1 and 16, in the passive heating mode S24, the supply of the underfloor air 17 to the living rooms 4A to 4D until a predetermined time has elapsed from the start of the first supply step S247. Is left behind (step S248). Since the underfloor air 17 is supplied for a certain period of time based on the opening degree of the dampers 20 (20a to 20d) of the living rooms 4A to 4D set in the first supply step S247, the remaining rooms 4A to 4A 4D can be effectively heated. About the remaining time, it can set suitably. In the present embodiment, in consideration of the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) of the ventilation means 10, the supply amount of the underfloor air 17 to the respective rooms 4A to 4D, etc., for example, 20 minutes to It is set to about 30 minutes.

  Next, in the passive heating mode S24, it is determined whether or not the temperature of each room 4A to 4D is equal to or higher than a predetermined temperature (step S249). About "predetermined temperature" of each living room 4A thru | or 4D, it can set suitably. In the present embodiment, for example, the temperature (19 ° C.) between the target temperature (for example, 20 ° C.) set in the first supply step S 247 and the temperature of the underfloor air 17 (18 ° C.) determined in step S 246. Set to Thereby, it is possible to determine whether the temperature of each of the living rooms 4A to 4D is rising toward the target temperature using the underfloor air 17.

  When the temperature of each room 4A to 4D is equal to or higher than the temperature (19 ° C.) (“Y” in step S249), the room 4A to 4D is effectively heated using the underfloor air 17. Can be judged. In such a case, the next step S250 is performed. On the other hand, when the temperature of each of the rooms 4A to 4D is lower than the above temperature (that is, the temperature of at least one of the rooms 4A to 4D is lower than the temperature) (“N” in step S249), the underfloor air 17 is used. Also, it can be determined that the living rooms 4A to 4D cannot be effectively heated. In this case, the passive heating mode S24 is interrupted and the heating mode S23 (shown in FIGS. 5 and 6) is performed. Thus, in this embodiment, even if the underfloor air 17 is supplied to each of the living rooms 4A to 4D for a certain period of time, when it is determined that each of the living rooms 4A to 4D is not sufficiently heated, the passive heating mode S24 is interrupted. The heating mode S23 is quickly performed. Accordingly, the living rooms 4A to 4D can be reliably heated.

  Next, in the passive heating mode S24, it is determined whether or not it is the first period (winter passive period) at the present through the steps S241 to S249 (step S250). If it is determined that the current period is the first period (“Y” in step S250), steps S241 to S250 are performed again. Thus, in the first period (winter passive period), the living rooms 4A to 4D can be continuously heated (air-conditioned) using only natural energy without using the air conditioner 16. An increase in cost can be prevented.

  On the other hand, when it is determined that the current time is outside the first period (winter passive period) (“N” in step S250), the series of processes in the passive heating mode S24 ends.

  In the passive heating mode S24 of the present embodiment, a mode in which the same air volume is set for the first floor fan 10Ba and the second floor fan 10Bb of the ventilation means 10 is shown, but the present invention is not limited to this. For example, similarly to the heating mode S23, the air volumes of the first-floor fan 10Ba and the second-floor fan 10Bb may be adjusted for each of the living room areas A1 and A2 based on the difference Va between the living rooms 4A to 4D.

  As FIG. 4 shows, the following step S4 is implemented by complete | finishing a series of processes of ventilation mode S22, heating mode S23, and passive heating mode S24 which were mentioned above. Thereby, in winter air-conditioning step S2, each living room 4A thru | or 4D can be efficiently heated (air-conditioned) according to the period to which the present belongs.

FIG. 18 is a flowchart showing an example of the processing procedure of the summer air conditioning step S3 of the present embodiment. As shown in FIGS. 1 and 18, in the summer air conditioning step S <b> 3, an intermediate period in which the air conditioner 16 does not require cooling, a cooling period in which the air conditioner 16 requires cooling, and an intermediate period and a cooling period are included. In the second period (hereinafter, simply referred to as “summer passive period”), different processing procedures are performed. Each period is as follows, for example. Note that the intermediate period, the cooling period, and the second period (summer passive period) are not limited to the illustrated period, and may be appropriately changed according to the climate of the area where the building B is completed. sell.
Interim period: April 28 to June 16, September 23 to October 25 Cooling period: August 1 to August 21 Second period (summer passive period): June 17 to July 31st, August 22nd to September 22nd

  In the summer air conditioning step S3, it is first determined whether the present time belongs to the intermediate period, the cooling period, or the second period (summer passive period) (step S31). These determinations are made by the control means 26 (shown in FIG. 3). When it is determined that the present is included in the intermediate period, the next ventilation mode S32 is performed. When it is determined that the current time is included in the cooling period, the next cooling mode S33 is performed. Furthermore, when it is determined that the present is included in the second period (summer passive period), the following passive cooling mode S34 is performed.

In the ventilation mode S32, the first space 9A and the second space 9B are blocked as in the ventilation mode S22 of the winter air conditioning step S2. As described above, the first space 9A and the second space 9B are shut off, and are supplied to the living rooms 4A to 4D by heat discharged during maintenance such as automatic cleaning of the filter of the air conditioner 16 or the like. It is possible to prevent the underfloor air 17 from being warmed. Furthermore, the fan 10B of the ventilation means 10 (in this embodiment, the first floor fan 10Ba and the second floor fan 10Bb) is operated. Thereby, the underfloor air 17 is supplied to each living room 4A thru | or 4D via the chamber box 9, the ventilation means 10, and the damper 20 (20a-20d). The air in the living rooms 4A to 4D is discharged to the outdoors by an exhaust fan (not shown) or the like. Thereby, each room 4A thru / or 4D is ventilated by the clean outside air. A series of processing in these ventilation modes S32 is performed by the control means 26. The air volume of the first floor fan 10Ba and the second floor fan 10Bb is set to the first air volume (for example, 87.5 m ³ / h). The damper 20 of each room 4A, 4B, 4C, or 4D is appropriately selected from the first opening to the fifth opening.

  Next, in the cooling mode S33, the cold air cooled by the air conditioner 16 is supplied to the living rooms 4A to 4D. FIG. 19 is a flowchart illustrating an example of a processing procedure in the cooling mode S33. A series of processing in the cooling mode S33 is performed by the control means 26 (shown in FIG. 3).

  In the cooling mode S33, first, a target temperature is set (step S330). The target temperature is a temperature that is desired to be maintained in each of the living rooms 4A to 4D by cooling with the air conditioner 16. The target temperature can be set as appropriate. The target temperature of the present embodiment is desirably set to, for example, 26 ° C. to 29 ° C. (28 ° C. in the present embodiment) from the viewpoint of preventing indoor heat stroke. The target temperature of the present embodiment may be set for each of the living rooms 4A to 4D, or may be the same. The target temperature is stored in the storage unit 34 and is read into the work memory 35.

  Next, in the cooling mode S33, as shown in FIGS. 1 and 3, the temperatures of the respective rooms 4A to 4D are detected (step S331). The temperature of each room 4A to 4D is detected by the room temperature detection means 25 (25a to 25d). The temperature of each room 4A to 4D is transmitted to the control means 26.

  Next, in the cooling mode S33, values W5 obtained by subtracting a predetermined target temperature from the temperatures of the living rooms 4A to 4D are respectively obtained (step S332). The value W5 is obtained for each of the living rooms 4A to 4D. The smaller this value W5, the lower the temperature of each of the living rooms 4A to 4D.

  Next, in the cooling mode S33, it is determined whether or not the value W5 of all the living rooms 4A to 4D is equal to or less than a predetermined second cooling threshold (step S333). In step S333, it is determined whether air conditioning (cooling) by the air conditioner 16 is necessary. Therefore, the second cooling threshold is preferably set to 0 ° C. or lower. The 2nd cooling threshold value of this embodiment is set as -1.5 ° C, for example. In addition, in order to aim at the energy-saving operation | movement of the air conditioner 16, reducing the temperature of each room 4A thru | or 4D, a 2nd cooling threshold is a numerical value larger than -1.5 degreeC (for example, -1.0 degreeC). May be set.

  When it is determined that the value W5 of all the living rooms 4A to 4D is equal to or lower than a predetermined second cooling threshold (for example, −1.5 ° C.) (“Y” in step S333), all the living rooms The temperature of 4A to 4D is lower than the target temperature (for example, 28 ° C.) and is sufficiently cooled. Therefore, it can be determined that air conditioning (cooling) by the air conditioner 16 is unnecessary. In such a case, the next air conditioning stop step S334 is executed. In addition, the process sequence of air-conditioning stop step S334 is the same as the process sequence of air-conditioning stop step S234 of heating mode S23 shown in FIG.

  On the other hand, when it is determined that the value W5 of all the living rooms 4A to 4D is larger than a predetermined second cooling threshold (for example, -1.5 ° C) ("N" in step S333), the living room Since there is a high possibility that at least one of the rooms 4A to 4D is not sufficiently cooled, it can be determined that air conditioning (cooling) by the air conditioner 16 is necessary. In such a case, a cooling step S335 for supplying the cold air cooled by the air conditioner 16 to each of the living rooms 4A to 4D is executed.

  FIG. 20 is a flowchart illustrating an example of a processing procedure of the cooling step S335. In the cooling step S335, first, the first space 9A and the second space 9B are communicated by the opening / closing part 9C of the chamber box 9 (step S820). Note that if the first space 9A and the second space 9B are already in communication, step S820 is omitted.

  Next, in the cooling step S335, cooling by the air conditioner 16 is started (step S821). In step S821 of the present embodiment, first, the air conditioner 16 is cooled. Further, the first floor fan 10Ba and the second floor fan 10Bb of the ventilation means 10 are operated. Thereby, in the first space 9 </ b> A, the air in the underfloor space 3 and the cold air cooled by the air conditioner 16 are mixed. The mixed air (cold air + underfloor air) is supplied to each of the living rooms 4A to 4D by the ventilation means 10. Thereby, cooling (air conditioning) by the air conditioner 16 can be realized while performing ventilation. In addition, when the cooling by the air conditioner 16 has already started, step S821 is omitted.

  Next, in the cooling step S335, it is determined whether or not the largest maximum value W5m among the values W5 of the respective rooms 4A, 4B, 4C or 4D is equal to or greater than a predetermined third cooling threshold. (Step S822). In step S822, it is determined whether more aggressive operation of the air conditioner 16 is necessary. Therefore, it is desirable that the third cooling threshold is set to a temperature higher than 0 ° C. The 3rd cooling threshold value of this embodiment is set as +0.5 ° C, for example.

  When the maximum value W5m is equal to or greater than the third cooling threshold (for example, + 0.5 ° C.) (“Y” in step S822), the temperature of the room 4A, 4B, 4C, or 4D is high. For this reason, the active operation step S823 for performing the active operation of the air conditioner 16 is performed. On the other hand, when the maximum value W5m is smaller than the third cooling threshold (for example, + 0.5 ° C.) (“N” in step S821), the respective rooms 4A to 4D are relatively cooled. For this reason, the efficient operation step S824 in which the efficient operation of the air conditioner 16 is performed is performed.

  In the active operation step S823 of this embodiment, the amount of cold air supplied to each of the rooms 4A to 4D and the fan for each room area A (in this embodiment, the first floor room area A1 and the second floor room area A2) The air volume of 10B (in this embodiment, 1st floor fan 10Ba and 2nd floor fan 10Bb) is adjusted. FIG. 21 is a flowchart illustrating an example of a processing procedure in the active operation step S823 of the present embodiment.

  In the active operation step S823 of the present embodiment, first, the amount of cold air supplied to each room 4A, 4B in the first floor room area A1 and the air volume of the first floor fan 10Ba are adjusted (first floor room area adjustment step). S831). FIG. 22 is a flowchart showing the processing procedure of the first-floor room area adjustment step S831.

  In the first-floor room area adjustment step S831, first, the smallest minimum value W6s among the values W5 of all the rooms included in the first-floor room area A1 (in the present embodiment, the first-floor rooms 4A and 4B), It is determined whether or not it is equal to or greater than a predetermined first cooling threshold (step S841). In this step S841, it is determined whether or not it is necessary to cool by maximizing the amount of cold air (mixed air) supplied to each of the rooms 4A and 4B included in the first floor room area A1. Therefore, it is desirable that the first cooling threshold value be set to a value larger than the third cooling threshold value (for example, + 0.5 ° C.) used for determining whether or not active operation is necessary. The first cooling threshold in this embodiment is set to + 1.5 ° C.

  When the minimum value W6s is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S841), all the rooms in the first-floor room area A1 (in this embodiment, the first-floor room 4A, The temperature of 4B) has risen significantly. For this reason, the supply amount of cold air (mixed air) to each of the living rooms 4A and 4B in the first-floor room area A1 is set to the maximum (step S842). In step S842, the dampers 20a and 20b (shown in FIG. 1) of the respective rooms 4A and 4B in the first-floor room area A1 are set to the largest fifth opening. As a result, the amount of cold air supplied to each room 4A, 4B in the first floor room area A1 can be maximized.

  On the other hand, when the minimum value W6s is less than the first cooling threshold (for example, “+ 1.5 ° C.”) (“N” in step S841), all the rooms in the first-floor room area A1 (in this embodiment, the first floor The temperature of the rooms 4A, 4B) does not increase significantly. Therefore, it is effective to individually adjust the amount of cold air (mixed air) supplied to each of the rooms 4A and 4B in the first-floor room area A1 for cooling. In this case, after the next step S843 and step S844 are executed, a room supply amount adjustment step for individually adjusting the amount of cold air supplied to each room 4A, 4B in the first floor room area A1 is performed. The room supply amount adjustment step of the present embodiment includes a third room supply amount adjustment step S845 and a fourth room supply amount adjustment step S846.

  FIG. 23 is a flowchart illustrating an example of a processing procedure of the third living room supply amount adjustment step S845. FIG. 24 is a flowchart illustrating an example of the processing procedure of the fourth living room supply amount adjustment step S846. In the third living room supply amount adjustment step S845 and the fourth living room supply amount adjustment step S846, the first floor living room is based on the value W5 of the first floor living room area A1 (the first floor living rooms 4A and 4B in this embodiment). The opening degree of the damper 20 (20a, 20b) in the room in the area A1 is adjusted. In this embodiment, the opening degree of the damper 20 is set to be larger as the room 4A or the room 4B has a larger value W5. Thereby, since more cold air (mixed air) is supplied to the living rooms 4A and 4B having a higher temperature, the air can be efficiently cooled.

  For each of the first opening to the fifth opening, the threshold range of the value W5 of the living rooms 4A and 4B (shown in FIG. 1) of the first floor living room area A1 is set. Similarly to the first living room supply amount adjustment step S645 and the second living room supply amount adjustment step S646 in the heating mode S23, the third living room supply amount adjustment step S845 has a threshold range compared to the fourth living room supply amount adjustment step S846. Is set to large. For this reason, even if the value W5 of the living rooms 4A and 4B (shown in FIG. 1) in the first-floor living room area A1 is distributed over a wide range, the third living room supply amount adjustment step S845 is performed for each of the living rooms 4A and 4B. The opening degree of 20a, 20b can be adjusted with good balance. The details of the third living room supply amount adjustment step S845 and the fourth living room supply amount adjustment step S846 will be described later.

  As shown in FIG. 22, in step S843, it is determined whether or not the largest maximum value W6m among the values W5 of the living rooms 4A and 4B (shown in FIG. 1) in the first-floor room area A1 is equal to or greater than the fourth cooling threshold. Is judged. If the maximum value W6m is significantly large, there is a high possibility that the values W5 of the living rooms 4A and 4B are widely distributed. Therefore, in order to determine the presence or absence of such a distribution, it is desirable that the fourth cooling threshold is set to be larger than the first cooling threshold (for example, + 1.5 ° C.). The 4th cooling threshold value of this embodiment is set as +3.0 ° C, for example.

  When the maximum value W6m is equal to or greater than a fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S843), the values in the respective rooms 4A and 4B (shown in FIG. 1) in the first-floor room area A1 There is a high possibility that W5 is widely distributed. In this case, the third living room supply amount adjustment step S845 is performed. On the other hand, when the maximum value W6m is less than the fourth cooling threshold (for example, + 3.0 ° C.), it is not possible to determine whether or not the value W5 of each of the rooms 4A and 4B is distributed over a wide range only by this step S843. Therefore, the next step S844 is performed.

  In the third room supply amount adjustment step S845, as shown in FIG. 23, the dampers 20 (20a or 20b) of the respective rooms 4A or 4B (shown in FIG. 1) in the first-floor room area A1 having the larger value W5 are arranged. The opening degree is set to a large value (steps S862 to S866). For example, the smallest first opening degree is set for the damper 20 of the living room 4A or 4B in which the value W5 is less than −3.0 ° C. (step S862). The damper 20 of the room 4A or 4B in which the value W5 is −3.0 ° C. (or higher) to −1.0 ° C. (less than) is set to a second opening larger than the first opening (step S863). ). The damper 20 of the living room 4A or 4B in which the value W5 is −1.0 ° C. (above) to + 1.0 ° C. (less than) is set to a third opening larger than the second opening (step S864). .

  Furthermore, the damper 20 (20a or 20b) of the living room 4A or 4B in which the value W5 is + 1.0 ° C. (above) to + 3.0 ° C. (below) is set to a fourth opening larger than the third opening. (Step S865). The damper 20 of the room 4A or 4B having the value W5 larger than + 3.0 ° C. is set to the fifth opening larger than the fourth opening (step S866).

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in the present embodiment, the living rooms 4A and 4B) in the first floor living room area A1 has been adjusted (step S867). When it is determined that the opening degrees of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 have been adjusted (“Y” in step S867), the series of processes in the third room supply amount adjustment step S845 ends. To do. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first floor living room area A1 are not adjusted ("N" in step S867), the other living rooms 4A in the first floor living room area A1 Alternatively, the 4B damper 20 is selected (step S868), and steps S861 to S867 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B of the first floor living room area A1 is adjusted based on the value W5, supply of cold air (mixed air) to each of the living rooms 4A to 4B The amount can be adjusted individually.

  In the present embodiment, the opening degree of the damper 20 is set to be larger for the living rooms 4A and 4B where the value W5 is larger. As a result, more cold air (mixed air) is supplied to the living rooms 4A and 4B having higher temperatures, so that the living rooms 4A and 4B can be efficiently cooled. In addition, about each threshold value which divided the opening degree of each damper 20 (20a, 20b), it is not necessarily limited to said value.

  As shown in FIG. 22, in step S844, it is determined whether or not the minimum value W6s is equal to or smaller than the fifth cooling threshold. If the minimum value W6s is significantly small, there is a high possibility that the values W5 of the respective rooms 4A and 4B in the first-floor room area A1 are widely distributed. Therefore, in order to determine the presence or absence of such a distribution, it is desirable that the fifth cooling threshold is set to be smaller than the second cooling threshold (for example, −1.5 ° C.). The 5th cooling threshold value of this embodiment is set as -3.0 ° C, for example.

  When the minimum value W6s is less than or equal to the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S844), the values W5 of the respective rooms 4A and 4B in the first-floor room area A1 are widely distributed. It is highly possible that In this case, the third room supply amount adjustment step S845 shown in FIG. 23 is performed. On the other hand, when the minimum value W6s is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S844), the minimum value W6s is relatively large. Moreover, the maximum value W6m is relatively small from the determination in step S843. Therefore, it is unlikely that the values W5 of the living rooms 4A and 4B in the first-floor room area A1 are widely distributed. In this case, the fourth living room supply amount adjustment step S846 is performed.

  In the fourth living room supply amount adjustment step S846, as shown in FIG. 24, as in the third living room supply amount adjustment step S845, each of the living rooms 4A or 4B in the first-floor living room area A1 having the larger value W5 is increased by the damper 20. The opening degree (20a, 20b (shown in FIG. 1)) is set to be large (steps S872 to S876). For example, the smallest first opening degree is set for the damper 20 of the living room 4A or 4B in which the value W5 is less than −1.5 ° C. (step S872). The damper 20 of the damper 20 of the living room 4A or 4B in which the value W5 is −1.5 ° C. (above) to −0.5 ° C. (less than) is set to a second opening larger than the first opening. (Step S873). The damper 20 of the living room 4A or 4B in which the value W5 is −0.5 ° C. (above) to + 0.5 ° C. (less than) is set to a third opening larger than the second opening (step S874). .

  Furthermore, the damper 20 (20a to 20d) of the living room 4A or 4B in which the value W5 is + 0.5 ° C. (above) to + 1.5 ° C. (below) is set to a fourth opening larger than the third opening. (Step S875). The damper 20 of the living room 4A or 4B having the value W5 larger than + 1.5 ° C. is set to the fifth opening larger than the fourth opening (step S876).

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in the present embodiment, the living rooms 4A and 4B) in the first floor living room area A1 has been adjusted (step S877). When it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B have been adjusted (“Y” in step S877), the series of processes in the fourth living room supply amount adjusting step S846 is completed. On the other hand, when it is determined that the opening degree of the dampers 20 of all the living rooms 4A and 4B is not adjusted (“N” in step S877), the dampers 20 of the other living rooms 4A or 4B are selected (step S878). Steps S871 to S877 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B in the first floor living room area A1 is adjusted based on the value W5, supply of cold air (mixed air) to the respective living rooms 4A and 4B The amount can be adjusted individually.

  In the present embodiment, the opening degree of the damper 20 is set to be larger for the living rooms 4A to 4D having the larger value W5. As a result, more cold air (mixed air) is supplied to the living rooms 4A and 4B having higher temperatures, so that the living rooms 4A and 4B can be efficiently cooled. In addition, about each threshold value which divided the opening degree of each damper 20 (20a and 20b), it is not necessarily limited to said value.

  Next, in the first-floor room area adjustment step S831 of this embodiment, as shown in FIG. 22, the air volume of the fan 10B (first-floor fan 10Ba) in the first-floor room area A1 is adjusted (fan air volume adjustment step S847). ~ S850). In the fan air volume adjustment steps S847 to S850, the air volume of the first-floor fan 10Ba is adjusted based on the value W5 (a value obtained by subtracting the target temperature from the temperature of the room 4A or 4B in the first-floor room area A1).

If it is determined in step S841 that the minimum value W6s of the value W5 is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S841), the maximum value W6m is the first cooling value. It can be significantly greater than the threshold. Therefore, it is effective to increase the air volume of the first-floor fan 10Ba and to actively supply cold air to the first-floor room area A1 including the high-temperature room 4A or 4B. Therefore, the air volume of the first floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S847).

Similarly, when it is determined in step S843 that the maximum value W6m of the first-floor room area A1 is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S843), 1 The air volume of the floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S848).

When it is determined in step S844 that the minimum value W6s of the first-floor room area A1 is not more than the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S844), the fan air volume adjustment step S847. It can be determined that it is not necessary to increase the air volume of the first-floor fan 10Ba as in S848 and S848. For this reason, the air volume of the first floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S849).

In step S844, when it is determined that the minimum value W6s of the first-floor room area A1 is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S844), the fan air volume adjustment step S847. It is not necessary to increase the air volume of the first-floor fan 10Ba as in S848, but it is effective to increase the air volume of the first-floor fan 10Ba rather than the fan air volume adjustment step S649. Therefore, the air volume of the first-floor fan 10Ba is set to the third air volume (for example, 400 m ³ / h) (fan air volume adjustment step S850).

  As described above, in the fan air volume adjustment steps S847 to S850, the air volume of the first-floor fan 10Ba is set to be larger as the maximum value W6m of the first-floor room area A1 is larger. Furthermore, the smaller the minimum value W6s of the first-floor room area A1, the smaller the air volume of the first-floor fan 10Ba. Therefore, the rooms 4A and 4B in the first floor room area A1 can be efficiently cooled. After the process of the fan air volume adjustment steps S847 to S850 is completed, a series of processes of the first-floor room area adjustment step S831 is completed.

  Next, as shown in FIGS. 1 and 21, in the active operation step S823, the amount of cold air supplied to each of the rooms 4C and 4D in the second-floor room area A2 and the air volume of the second-floor fan 10Bb are adjusted. (2nd floor living room area adjustment step S832). FIG. 25 is a flowchart showing the procedure of the second-floor room area adjustment step S832.

  In the second-floor room area adjustment step S832, first, the smallest minimum value W7s among the values W5 of all the rooms (in the present embodiment, the second-floor rooms 4C and 4D) included in the second-floor room area A2 is: It is determined whether or not a predetermined first cooling threshold value is exceeded (step S851). The first cooling threshold is set to + 1.5 ° C. as in the first-floor room area adjustment step S831.

  When the minimum value W7s is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S851), all the rooms in the second-floor room area A2 (in the present embodiment, the second-floor room 4C) Since the temperature of 4D) is significantly increased, the supply amount of cold air (mixed air) to each of the living rooms 4C and 4D in the second-floor room area A2 is set to the maximum (step S852). In this case, the dampers 20c and 20d (shown in FIG. 1) of the respective rooms 4C and 4D in the second-floor room area A2 are set to the largest fifth opening.

  On the other hand, when the minimum value W7s is less than the first cooling threshold (for example, “+ 1.5 ° C.”) (“N” in step S851), the temperatures of all the rooms 4C and 4D in the second-floor room area A2 are greatly increased. Since it is not rising, it is effective to individually adjust the amount of cold air (mixed air) supplied to the living rooms 4C and 4D in the second-floor room area A2 for cooling. Therefore, similarly to the first floor living room area adjustment step S831, the third living room supply amount adjustment step S855 and the fourth living room supply amount adjustment step S856 are performed.

  Next, in the second-floor room area adjustment step S832, is the largest maximum value W7m among the values W5 of the respective rooms 4C and 4D (shown in FIG. 1) of the second-floor room area A2 greater than or equal to the fourth cooling threshold? It is determined whether or not (step S853). The 4th cooling threshold value of this embodiment is set to +3.0 degreeC similarly to 1st floor room area adjustment step S831.

  When the maximum value W7m is greater than or equal to the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S853), the values in the respective rooms 4C and 4D (shown in FIG. 1) in the second-floor room area A2 There is a high possibility that W5 is widely distributed. In this case, the third living room supply amount adjustment step S855 is performed. On the other hand, when the maximum value W7m is less than the fourth cooling threshold (for example, + 3.0 ° C.), it is not possible to determine whether or not the value W5 of each of the rooms 4C and 4D is distributed over a wide range only by this step S853. Therefore, the next step S854 is performed.

  The third living room supply amount adjustment step S855 is the same processing procedure as the third living room supply amount adjustment step S845 (shown in FIG. 23) of the first floor living room area adjustment step S831. Therefore, since the opening degree of the damper 20 of each living room 4C and 4D in the second floor living room area A2 is adjusted based on the value W5, the amount of cold air (mixed air) supplied to each living room 4C and 4D is Can be adjusted individually. Therefore, the living rooms 4C and 4D can be efficiently cooled.

  As shown in FIG. 25, in step S854, it is determined whether or not the minimum value W7s is equal to or less than a fifth cooling threshold (for example, −3.0 ° C.). The fifth cooling threshold of the present embodiment is set to, for example, −3.0 ° C., similarly to the first-floor room area adjustment step S831.

  When the minimum value W7s is less than or equal to the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S854), the values W5 of the respective rooms 4C and 4D in the second-floor room area A2 are widely distributed. Therefore, the third room supply amount adjustment step S855 is performed. On the other hand, when the minimum value W7s is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S854), the value W5 of each room 4C and 4D in the second-floor room area A2 is wide. Is unlikely to be distributed. In this case, the fourth living room supply amount adjustment step S856 is performed.

  The fourth living room supply amount adjustment step S856 is the same processing procedure as the fourth living room supply amount adjustment step S846 (shown in FIG. 24) of the first floor living room area adjustment step S831. In the fourth room supply amount adjustment step S856, the threshold range is set smaller than that in the third room supply amount adjustment step S855. For this reason, even if the value W5 of each of the rooms 4C and 4D (shown in FIG. 1) in the second-floor room area A2 is not distributed over a wide range, the opening degree of the dampers 20c and 20d is determined for each of the rooms 4C and 4D. It can be adjusted more finely and well-balanced. Therefore, since the supply amount of the cold air (mixed air) to each of the living rooms 4C and 4D is adjusted individually, it can be efficiently cooled.

  As shown in FIG. 25, in the second-floor room area adjustment step S832 of the present embodiment, the air volume of the fan 10B (second-floor fan 10Bb) in the second-floor room area A2 is adjusted (fan air volume adjustment steps S857 to S860). . In the fan air volume adjustment steps S857 to S860, the air volume of the second-floor fan 10Bb is adjusted based on the value W5 of the respective rooms 4C and 4D of the second-floor room area A2. The fan air volume adjustment steps S857 to S860 are the same processing procedure as the fan air volume adjustment steps S847 to S850 of the first-floor room area adjustment step S831 shown in FIG.

  Therefore, in the fan air volume adjustment steps S857 to S860, the larger the maximum value W7m of the value W5 in the second floor room area A2, the larger the air volume of the second floor fan 10Bb. Furthermore, the smaller the minimum value W7s of the second-floor room area A2, the smaller the air volume of the second-floor fan 10Bb. Therefore, the respective rooms 4C and 4D in the second-floor room area A2 can be efficiently cooled. After the process of the fan air volume adjustment steps S857 to S860 is completed, the series of processes of the second-floor room area adjustment step S832 is completed.

  In this way, the fan air volume adjustment steps S847 to S850 (shown in FIG. 22) of the first floor room area adjustment step S831 and the fan air volume adjustment steps S857 to S860 of the second floor room area adjustment step S832 are brought to room temperature throughout the day. The air volume of the fan 10Ba or 10Bb is adjusted for each of the room areas A1 and A2 that are likely to cause a difference. Thereby, since cold air can be positively supplied by the fan 10Ba or 10Bb to the room area A1 or A2 including the high temperature room where the value W5 is relatively large, each room can be efficiently cooled.

  Next, as shown in FIG. 21, in the active operation step S823, prior to the air conditioning temperature adjustment steps S834 and S835 for adjusting the set temperature of the next air conditioner 16, the value W5 of each of the rooms 4A to 4D is set. Of these, it is determined whether or not the maximum value W5m is equal to or greater than a fourth cooling threshold (for example, + 3.0 ° C.), or the smallest minimum value W5s is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.). (Step S833). In step S833, it is determined whether or not the set temperature of the air conditioner 16 needs to be significantly lowered.

  When it is determined that the maximum value W5m is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) or the minimum value W5s is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.) (in step S833, “ Y "), the temperature of at least one living room (in this embodiment, the living room 4A, 4B, 4C, or 4D) is significantly increased. For this reason, the set temperature of the air conditioner 16 is set to the difference between the target temperature (for example, 28 ° C.) and the first subtraction temperature (air conditioning temperature adjustment step S834). About 1st subtraction temperature, it can set suitably. The 1st subtraction temperature of this embodiment is set as -5 ° C, for example.

  On the other hand, when the maximum value W5m is less than the fourth cooling threshold (for example, + 3.0 ° C.) and the minimum value W5s is less than the first cooling threshold (for example, + 1.5 ° C.) (“N” in step S833). ), The temperature of all the living rooms (in this embodiment, the living rooms 4A to 4D) is not increased. For this reason, it can be determined that it is not necessary to lower the set temperature of the air conditioner 16 as much as step S834. Accordingly, the set temperature of the air conditioner 16 is set to the difference between the target temperature (for example, 28 ° C.) and the second subtracted temperature (air conditioning temperature adjustment step S835). About 2nd subtraction temperature, if it is larger than 1st subtraction temperature, it can set suitably. The 2nd subtraction temperature of this embodiment is set as -2 degreeC, for example. As described above, in the air conditioning temperature adjustment steps S834 and S835, the set temperature is decreased as the maximum value W5m (and the minimum value W5s) is increased, so that the respective rooms 4A to 4D can be effectively cooled.

  Next, in the active operation step S823 of the present embodiment, the set air volume of the air conditioner 16 is adjusted (step S836). The set air volume Fw of the air conditioner 16 of the present embodiment is defined by the above formula (1), similarly to the heating step S235. Therefore, since the set air volume Fw of the air conditioner 16 is set to be larger as the total air volume Tf of the fan 10B is larger, the air cooled by the air conditioner 16 is changed to each living room (in the present embodiment, the living rooms 4A to 4D). ) Can be effectively supplied. Moreover, since the set air volume Fw is set to a value obtained by subtracting the ventilation air volume Vf necessary for the building B from the total air volume Tf, the underfloor air 17 necessary for ventilation can also be supplied to each room. In the present embodiment, after the process of step S836 is completed, a series of processes of the active operation step S823 and the cooling step S335 are completed.

  FIG. 26 is a flowchart illustrating an example of the processing procedure of the efficient operation step S824 of the present embodiment. As described above, in the efficient operation step S824, the air conditioner 16 is efficiently operated. In the efficiency operation step S824, first, the first space 9A and the second space 9B are communicated with each other by the opening / closing part 9C of the chamber box 9 (step S880). If the first space 9A and the second space 9B are already in communication, step S880 is omitted.

  Next, in the efficiency operation step S824, the humidity in each of the rooms 4A to 4D is detected (step S881). The humidity of each room 4A to 4D is detected by the room humidity detection means 29 (29a to 29d). The humidity of each living room 4A to 4D is transmitted to the control means 26.

  Next, in the efficient operation step S824, it is determined whether or not all the living rooms 4A to 4D are equal to or higher than a predetermined humidity (for example, 70RH) (step S882). When it is determined that all the living rooms 4A to 4D have a predetermined humidity (for example, 70RH) or higher ("Y" in step S882), the next dehumidifying operation step S883 is performed. On the other hand, when it is determined that all the living rooms 4A to 4D are less than a predetermined humidity (for example, 70RH) ("N" in step S882), it is not necessary to dehumidify each of the living rooms 4A to 4D. The next efficient cooling operation step S884 is performed.

FIG. 27 is a flowchart illustrating an example of a processing procedure of the dehumidifying operation step S883. In the dehumidifying operation step S883 of the present embodiment, first, the opening degree of the dampers 20a to 20d of each of the rooms 4A to 4D is maintained (step S887), and the fan 10B of the ventilation means 10 (first floor fan 10Ba and second floor fan 10Bb). Is set to the third air volume (for example, 400 m ³ / h) (step S888). Then, the air conditioner 16 is dehumidified (step S889), and the set temperature of the air conditioner 16 is maintained (step S890). Further, the set air volume of the air conditioner 16 is set to the second air conditioning air volume (for example, 625 m ³ / h) based on the set air volume Fw defined by the above formula (1) (step S891).

  With such a dehumidifying operation step S883, the dehumidifying operation of the air conditioner 16 prevents deteriorating the cooling efficiency and dehumidifies each of the rooms 4A to 4D without performing the efficiency cooling operation step S884 described later. It can be cooled efficiently.

FIG. 28 is a flowchart illustrating an example of a processing procedure of the efficiency cooling operation step. In the efficiency cooling operation step S884, the current cooling capacity of the air conditioner 16 is calculated (step S893). The cooling capacity Ec of the air conditioner 16 is obtained by the following formula (3).
Ec = (Ta−Tb) × Af × Hs / 1000 (3)
Here, each constant and variable are as follows.
Ta: Temperature of the air intake unit of the air conditioner (℃)
Tb: Temperature of exhaust section of air conditioner (° C)
Af: Air flow rate of air conditioner (m ³ / h)
Hs: Specific heat of air (0.35 Wh / m ³ · ° C)

  FIG. 15B is a graph showing the relationship among COP (Coefficient of Performance), sensible heat load (kW), latent heat load (kW), cooling power consumption (kW), and cooling capacity (kW). Generally, when the cooling capacity Ec is 2 kW or more, the cooling efficiency is poor. In such a case, it is desirable that the air conditioner 16 is operated, for example, by increasing the set temperature or decreasing the set air volume so that the cooling capacity Ec approaches 2 kW.

  Next, as shown in FIG. 28, in the efficiency cooling operation step S884, it is determined whether or not the current cooling efficiency of the air conditioner 16 is poor (step S894). In this embodiment, when the current cooling capacity Ec is 2 kW or more, it is determined that the cooling efficiency is poor. As described above, when the cooling efficiency is poor, the air conditioner 16 is efficiently operated.

  If it is determined that the current air conditioner 16 has poor cooling efficiency (cooling capacity Ec is 2 kW or more) (“Y” in step S894), the air conditioner 16 is operated before the efficient operation. Step S895 is performed. On the other hand, when it is determined that the current cooling efficiency of the air conditioner 16 is not bad (the cooling capacity Ec is less than 2 kW) (“N” in step S894), the air conditioner 16 has already been efficiently operated. It has been broken. For this reason, a series of the efficiency operation step S824 and the cooling step S335 (shown in FIG. 20) while the current operation state (set temperature and set air volume) of the air conditioner 16 and the air volume of the fan 10B are maintained. The process ends.

Next, in the efficiency cooling operation step S884, it is determined whether or not the set temperature of the air conditioner 16 is lower than a target temperature (for example, 28 ° C.) (step S895). When the set temperature of the air conditioner 16 is lower than the target temperature (“Y” in step S895), the living rooms 4A, 4B, 4C, or 4D are cooled to the target temperature even if the set temperature is slightly increased. Can do. In such a case, while the opening degree of the dampers 20a to 20d is maintained (step S896), the air volume of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) is set to the third air volume (for example, 400 m ³ / h). The temperature is set (step S897), and the set temperature of the air conditioner 16 is set to a large value (step S898). Note that an increase in the set temperature of the air conditioner 16 is set as appropriate. The increase in this embodiment is set to + 1 ° C., for example.

Further, the set air volume of the air conditioner 16 is set to the second air conditioning air volume (for example, 625 m ³ / h) based on the set air volume Fw defined by the above formula (1) (step S899). Thereby, in the efficiency operation step S824, even if the set temperature of the air conditioner 16 is increased, the living rooms 4A to 4D are efficiently cooled, so that the cooling efficiency can be increased.

When the set temperature of the air conditioner 16 is equal to or higher than the target temperature (“N” in step S895), if the set temperature is further increased, each room 4A, 4B, 4C, or 4D is maintained at the target temperature. There is a risk that it will not be possible. Therefore, the opening degree of the dampers 20a to 20d is maintained (step S900), and the air volume of the fan 10B (first floor fan 10Ba and second floor fan 10Bb) is set to the first air volume (for example, 87.5 m ³ / h). Then, the set temperature of the air conditioner 16 is maintained (step S902).

Further, the set air volume of the air conditioner 16 is set to a silent air volume (for example, 325 m ³ / h) based on the set air volume Fw defined by the above formula (1) (step S903). Thereby, in efficient operation step S824, each living room 4A thru | or 4D can be cooled efficiently, preventing the deterioration of the cooling efficiency of the air conditioner 16. FIG.

  Next, in the efficiency cooling operation step S884, the air conditioner 16 and the fan 10B are maintained in the state where the set temperature, the set air volume, and the air volume of the fan 10B set in steps S896 to S903 are maintained. Are left behind (step S904). Thereby, while preventing the deterioration of the cooling efficiency of the air conditioner 16, each of the living rooms 4A to 4D can be efficiently cooled. The remaining time can be set as appropriate. In the present embodiment, considering that the respective rooms 4A to 4D are efficiently cooled by the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B set in the efficient cooling operation step S884, for example, It is desirable to set it to about 5 minutes.

  As shown in FIG. 20, after the dehumidifying operation step S883 and the efficiency cooling operation step S884 are completed, the series of processes of the efficiency operation step S824 and the cooling step S335 (shown in FIG. 18) is completed.

  Next, as shown in FIG. 19, in the cooling mode S33, it is determined whether or not a predetermined end time has elapsed since the start of the cooling mode S33 (step S336). The end time can be set as appropriate. In the present embodiment, considering that the respective rooms 4A to 4D are effectively cooled by the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B set in the cooling mode S33, for example, For example, it is desirable to set for about 30 minutes.

  When it is determined that the end time has elapsed (“Y” in step S336), the series of processing in the cooling mode S33 ends. On the other hand, when it is determined that the end time has not elapsed ("N" in step S336), steps S330 to S336 are performed again. Thereby, in cooling mode S33, based on the temperature of each living room 4A, 4B, 4C or 4D which changes every moment, the opening degree of the damper 20, the set temperature of the air conditioner 16, the set air volume, and the fan 10B Since the air volume is adjusted, each of the rooms 4A to 4D can be effectively cooled.

  Next, in the passive cooling mode S34, the underfloor air 17 is supplied to the living rooms 4A to 4D, whereby the living rooms 4A to 4D are air-conditioned while being ventilated. FIG. 29 is a flowchart illustrating an example of a processing procedure in the passive cooling mode S34. A series of processing in the passive cooling mode S34 is performed by the control means 26.

  In the passive cooling mode S34, first, as shown in FIGS. 1 and 3, the temperatures of the respective rooms 4A to 4D are detected (step S341). Next, in the passive cooling mode S34, the temperature of the outside air is detected (step S342). Next, in the passive cooling mode S34, the temperature of the underfloor air 17 is detected (step S343). The temperature of each living room 4A to 4D, the temperature of the outside air, and the temperature of the underfloor air 17 are transmitted to the control means 26.

  Next, in the passive cooling mode S34, it is determined whether or not the temperature of each of the living rooms 4A to 4D is lower than the temperature at which the cooling operation by the air conditioner 16 is required (step S344). The “temperature at which the cooling operation by the air conditioner 16 is required” can be appropriately set according to the structure of the building B, the cooling capacity (temperature) by the underfloor air 17, and the like. In this embodiment, for example, the temperature is set to about 31 ° C.

  When the temperature of each of the living rooms 4A to 4D is lower than the temperature (for example, 31 ° C.) at which the cooling operation by the air conditioner 16 is required (“Y” in step S344), the underfloor air 17 is used for cooling. It can be determined that (air conditioning) is possible. In such a case, the next step S345 is performed. On the other hand, when the temperature of each of the rooms 4A to 4D is equal to or higher than the temperature (eg, 31 ° C.) at which the cooling operation by the air conditioner 16 is required (“N” in step S344), the underfloor air 17 is used. However, it can be determined that the living rooms 4A to 4D cannot be effectively cooled. In such a case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 18 and 19) is performed.

  Next, in the passive cooling mode S34, it is determined whether or not the temperature of the outside air is lower than a predetermined temperature (step S345). The “predetermined temperature” of the outside air can be appropriately set according to, for example, the structure of the building B, the cooling capacity (temperature) by the underfloor air 17, and the like. In this embodiment, for example, the temperature is set to 30 ° C.

  When the temperature of the outside air is lower than a predetermined temperature (for example, 30 ° C.) (“Y” in step S345), since the influence of the temperature rise of the living rooms 4A to 4D due to the outside air is small, the underfloor air 17 is used. Thus, it can be determined that each of the living rooms 4A to 4D can be cooled (air-conditioned). In such a case, the next step S346 is performed. On the other hand, when the temperature of the outside air is equal to or higher than a predetermined temperature (for example, 30 ° C.) (“N” in step S345), each of the rooms 4A to 4D is affected by the outside air even if the underfloor air 17 is used. Can not be effectively cooled. In such a case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 18 and 19) is performed.

  Next, in the passive cooling mode S34, it is determined whether or not the temperature of the underfloor air 17 is lower than a predetermined temperature (step S346). The “predetermined temperature” of the underfloor air 17 can be appropriately set according to the structure of the building B, for example. In this embodiment, for example, it is set to 22 ° C.

  When the temperature of the underfloor air 17 is lower than a predetermined temperature (for example, 22 ° C.) (“Y” in step S346), each of the living rooms 4A to 4D is utilized using the underfloor air 17 having a relatively low temperature. It can be determined that can be cooled (air-conditioned). In such a case, the next second supply step S347 is performed. On the other hand, when the temperature of the underfloor air 17 is equal to or higher than a predetermined temperature (for example, 22 ° C.) (“N” in step S346), the use of the underfloor air 17 also has the effect of the living rooms 4A to 4D. Therefore, it can be determined that cooling cannot be performed. In such a case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 18 and 19) is performed.

  Next, in the passive cooling mode S34, the underfloor air 17 is supplied to the living rooms 4A to 4D (second supply step S347). In the second supply step S347, the temperature of each of the living rooms 4A to 4D is lower than the temperature at which the cooling operation by the air conditioner 16 is required, and the temperature of the outside air is determined in advance based on the determinations of steps S344 to S346. Only when it is determined that the temperature of the underfloor air 17 is lower than a predetermined temperature. Therefore, in the second supply step S347, the temperature of each of the rooms 4A to 4D, the temperature of the outside air, and the temperature of the underfloor air 17 are relatively low, so that the underfloor air 17 is used without using the air conditioner 16. Thus, the living rooms 4A to 4D can be effectively cooled (air-conditioned). Therefore, an increase in air conditioning cost can be prevented. FIG. 30 is a flowchart illustrating an example of the processing procedure of the second supply step S347.

As shown in FIGS. 1 and 30, in the second supply step S347 of the present embodiment, first, the air volume (total supply of the underfloor air 17) of the fan 10B (the first floor fan 10Ba and the second floor fan 10Bb) of the ventilation means 10 is used. Amount) is set (step S911). The air volume of the first-floor fan 10Ba and the second-floor fan 10Bb of the present embodiment is set to a fourth air volume (for example, 550 m ³ / h), for example, because the natural ventilation is less than in winter. In step S911, as shown in FIGS. 1 and 2, the first space 9A and the second space 9B are blocked by the opening / closing part 9C of the chamber box 9. As a result, the air in the first space 9A of the chamber box 9 is purified from the exhaust port 14 via the duct 10A and the air purifying device 10C, and then each room 4A via the damper 20 (20a to 20d). To the floor space 4 such as 4D or the like.

  Next, in the second supply step S347, a difference Vb between the temperature of each of the living rooms 4A to 4D and a predetermined target temperature is obtained (step S912). The target temperature of the present embodiment is preferably set to 28 ° C., for example, from the viewpoint of preventing indoor heat stroke. The target temperature may be set for each of the living rooms 4A to 4D. The target temperature is stored in the storage unit 34 in advance.

  The difference Vb is obtained for each of the living rooms 4A to 4D. The difference Vb in the present embodiment is obtained as a value obtained by subtracting the target temperature from the temperature of each of the living rooms 4A to 4D, similarly to the value W5 of the cooling mode S33. The smaller this value (difference Vb), the lower the temperature of each of the rooms 4A to 4D.

  Next, in 2nd supply step S347, the opening degree of the damper 20 (20a-20d) of each living room 4A thru | or 4D is adjusted based on the said difference Vb of each living room 4A thru | or 4D (step S913-step S919). . In the present embodiment, the larger the difference Vb is, the larger the opening degree of the damper 20 (the supply amount of the underfloor air 17) is set. Thereby, since the colder underfloor air 17 is supplied to the living rooms 4A to 4D having higher temperatures, each of the living rooms 4A to 4D can be efficiently cooled.

  For example, the damper of the living room 4A, 4B, 4C, or 4D having the difference Vb of less than −1.5 ° C. is set to the smallest first opening (step S914). The damper 20 of the living room 4A, 4B, 4C, or 4D in which the difference Vb is −1.5 ° C. (or higher) to −0.5 ° C. (less than) is set to a second opening larger than the first opening. (Step S915). The damper 20 of the living room 4A, 4B, 4C, or 4D in which the difference Vb is −0.5 ° C. (above) to + 0.5 ° C. (less than) is set to a third opening larger than the second opening. (Step S916).

  Further, the damper 20 (20a to 20d) of the room 4A, 4B, 4C, or 4D in which the difference Vb is + 0.5 ° C. (above) to + 1.5 ° C. (below) is a fourth larger than the third opening degree. The opening is set (step S917). The damper 20 of the room 4A, 4B, 4C, or 4D having the difference Vb larger than + 1.5 ° C. is set to the fifth opening larger than the fourth opening (step S918).

  And it is judged whether the opening degree of the damper 20 (20a-20d) of all the living rooms 4A thru | or 4D was adjusted (step S919). When it is determined that the openings of the dampers 20 of all the living rooms 4A to 4D have been adjusted, the next step S348 (shown in FIG. 29) is performed. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A to 4D are not adjusted, the dampers 20 of the other living rooms 4A to 4D are selected (step S920), and steps S913 to S919 are performed again. Is done. Thereby, the opening degree of the damper 20 of all the living rooms 4A to 4D can be adjusted based on the difference Vb. Therefore, the supply amount of the underfloor air 17 to the living rooms 4A to 4D can be individually adjusted.

  For the threshold value of the difference Vb (in this embodiment, “+ 1.5 ° C.”, “+ 0.5 ° C.”, “−0.5 ° C.”, “−1.5 ° C.”), for example, ventilation means It can be appropriately changed according to the air volume of the ten fans 10B (first floor fan 10Ba and second floor fan 10Bb).

  Next, as shown in FIG. 29, in the passive cooling mode S34, the supply of the underfloor air 17 to each of the living rooms 4A to 4D is left until a predetermined time has elapsed from the start of the second supply step S347. (Step S348). Since the underfloor air 17 is supplied for a certain period of time based on the opening degree of the dampers 20 (20a to 20d) of the living rooms 4A to 4D set in the second supply step S347, the remaining rooms 4A to 4A 4D can be effectively cooled. About the remaining time, it can set suitably. In this embodiment, for example, it is set to about 20 minutes to 30 minutes.

  Next, in the passive cooling mode S34, it is determined whether or not the temperature of each of the living rooms 4A to 4D is lower than a predetermined temperature (step S349). About "predetermined temperature" of each living room 4A thru | or 4D, it can set suitably. The temperature of the present embodiment is set to 28 ° C., for example, based on the target temperature set in the second supply step S347.

  When the temperature (28 ° C.) of each of the living rooms 4A to 4D is lower than the above temperature (“Y” in step S349), it can be determined that the air is effectively cooled using the underfloor air 17. In such a case, the next step S350 is performed. On the other hand, when the temperature of each of the rooms 4A to 4D is equal to or higher than the temperature (that is, the temperature of at least one of the rooms 4A to 4D is equal to or higher than the temperature) ("N" in step S349), the underfloor air 17 is used. In addition, it can be determined that the living rooms 4A to 4D cannot be effectively cooled. In this case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 18 and 19) is performed. Thus, in this embodiment, even if the underfloor air 17 is supplied to each of the rooms 4A to 4D for a certain period of time, when it is determined that the rooms 4A to 4D are not sufficiently cooled, the passive cooling mode S34 is interrupted. The cooling mode S33 is quickly performed. Accordingly, each of the living rooms 4A to 4D can be reliably cooled.

  Next, in the passive cooling mode S34, it is determined whether or not it is the second period (summer passive period) at the present through the steps S341 to S349 (step S350). If it is determined that the current period is the second period (“Y” in step S350), steps S341 to S350 are performed again. Thus, in the second period (summer passive period), each of the living rooms 4A to 4D can be effectively cooled (air-conditioned) using only natural energy without using the air conditioner 16. An increase in cost can be prevented. On the other hand, when it is determined that the current time is outside the second period (summer passive period) ("N" in step S350), the series of processes in the passive cooling mode S34 ends.

  When the series of processes in the summer air conditioning step S3 including the ventilation mode S32, the cooling mode S33, and the passive cooling mode S34 described above are completed, the next step S4 (shown in FIG. 4) is performed. Thereby, in summer air-conditioning step S3, each living room 4A thru | or 4D can be efficiently cooled (air-conditioned) according to the period to which the present belongs.

  Next, in the air conditioning method of this embodiment, as shown in FIG. 4, after the winter air conditioning step S2 or the summer air conditioning step S3 is performed, it is determined whether or not there is an air conditioning method end command (step S4). The termination command is issued by a resident or the like via the control means 26, for example. In step S4, when there is an end command, a series of processes of the present embodiment ends. On the other hand, if there is no end command, steps S1 to S4 are performed again.

  Thus, in the air conditioning method of the present embodiment, since the heating mode S23 and the cooling mode S33 are included, the living rooms 4A to 4D can be comfortably air-conditioned throughout the year using the air conditioner 16. Further, in the heating mode S23 and the cooling mode S33, since the supply amount of warm air or cold air can be individually adjusted based on the temperature difference between the temperature of each of the rooms 4A to 4D and the target temperature, each of the rooms 4A to 4D. Can be efficiently cooled and heated. Further, in the air conditioning method of the present embodiment, since the passive heating mode S24 and the passive cooling mode S34 are included, the living rooms 4A to 4D can be efficiently cooled and heated using the underfloor air.

  Further, as described above, the total supply amount of the underfloor air 17 in the passive heating mode S24 (second air volume in the present embodiment) is the total supply amount of the underfloor air 17 in the passive cooling mode S34 (in the present embodiment). 4th air volume). This takes into account the natural ventilation in winter, which is larger than the natural ventilation in summer. Thereby, it can suppress that each living room 4A thru | or 4D becomes overdrying in winter.

  As shown in FIG. 8, in step S622 of the heating step 235 of the present embodiment, the smallest minimum value W1s among the values W1 of the living rooms 4A to 4D is the third heating threshold (for example, −0.5 ° C.). ) (“N” in step S622), the aspect in which the efficiency operation step S624 is performed is implemented, but is not limited thereto. In step S622, for example, even when the values W1 of the respective rooms 4A to 4D are distributed over a wide range of, for example, −0.5 ° C. to + 3.0 ° C., the efficient operation step S624 is performed. In the efficiency operation step S624, as shown in FIG. 14, the supply amount of warm air to each of the rooms 4A to 4D is maintained (steps S684 and S688), and the air volume of the first floor fan 10Ba and the second floor fan 10Bb. Are uniformly set (step 685 and step S689). In such a case, it is difficult to efficiently heat each of the living rooms 4A to 4D. Accordingly, the active operation step S623 in which the supply amount of warm air to the living rooms 4A to 4D and the air volume of the first-floor fan 10Ba and the second-floor fan 10Bb are adjusted based on the value W1 of each of the living rooms 4A to 4D. Is preferably implemented. FIG. 31 is a flowchart showing an example of a processing procedure of heating step S235 according to another embodiment of the present invention.

  In this embodiment, instead of step S622 shown in FIG. 8, the values W1 of all the living rooms 4A to 4D are equal to or higher than a predetermined third heating threshold (for example, −0.5 ° C.). It is determined whether or not it is equal to or less than a predetermined sixth heating threshold (step S625). About a 6th heating threshold value, it can set suitably. As described above, it is desirable that the active operation step S623 is performed when the values W1 of the living rooms 4A to 4D are distributed over a wide range. For this reason, it is desirable that the sixth heating threshold value is set to be smaller than the second heating threshold value (for example, + 1.5 ° C.) used in step S233 for determining the execution of the heating step S235. The sixth heating threshold value of the present embodiment is set to + 0.5 ° C., for example.

  When the value W1 of all the living rooms 4A to 4D is not less than the third heating threshold (for example, −0.5 ° C.) and not more than the sixth heating threshold (for example, + 0.5 ° C.) (in step S625, Y) The living rooms 4A to 4D are relatively warm, and the values W1 of the living rooms 4A to 4D are not distributed over a wide range. For this reason, the efficient operation step S624 in which the efficient operation of the air conditioner 16 is performed is performed. On the other hand, when the values W1 of all the living rooms 4A to 4D are not less than the third heating threshold (for example, −0.5 ° C.) and not less than the sixth heating threshold (for example, + 0.5 ° C.) (in step S625). , N), the values W1 of the living rooms 4A to 4D may be distributed over a wide range. For this reason, active driving step S623 is implemented.

  Thus, in heating step S235 of this embodiment, when the value W1 of each living room 4A thru | or 4D is distributed over a wide range, since active operation step S623 is implemented, each living room 4A thru | or 4D is made effective. Can be heated.

  FIG. 32 is a flowchart illustrating an example of a processing procedure of the cooling step S335 according to another embodiment of the present invention. From the same viewpoint as the heating step S235 shown in FIG. 31, whether or not the largest maximum value W5m among the values W5 of the living rooms 4A to 4D is equal to or greater than a third cooling threshold (for example, + 0.5 ° C.). In place of step S822 (shown in FIG. 20), the values W5 of all the living rooms 4A to 4D are equal to or higher than the sixth cooling threshold (for example, −0.5 ° C.) and the third cooling threshold (for example, , + 0.5 ° C.) or less, step S825 is preferably performed.

  When the value W5 of all the living rooms 4A to 4D is not less than the sixth cooling threshold (for example, −0.5 ° C.) and not more than the third cooling threshold (for example, + 0.5 ° C.) (in step S825, Y) The living rooms 4A to 4D are relatively cool, and the values W5 of the living rooms 4A to 4D are not distributed over a wide range. For this reason, the efficient operation step S824 in which the efficient operation of the air conditioner 16 is performed is performed. On the other hand, when the value W5 of all the living rooms 4A to 4D is not less than the sixth cooling threshold (for example, −0.5 ° C.) and not less than the third cooling threshold (for example, + 0.5 ° C.) (in step S825). , N), the values W5 of the respective rooms 4A to 4D may be distributed over a wide range. For this reason, active driving step S823 is implemented.

  As described above, in the cooling step S335 of this embodiment, when the values W5 of the living rooms 4A to 4D are distributed over a wide range, the active operation step S823 is performed, so that each of the living rooms 4A to 4D is effectively used. Can be cooled.

As shown in FIG. 10, when it is determined in step S644 of the first-floor room area adjustment step S631 that the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.) (in step S644, “ N "), the second room supply amount adjustment step S646, and the fan air amount adjustment step S650 for setting the air amount of the first floor fan 10Ba to the third air amount (for example, 400 m ³ / h) are shown. However, it is not limited to this.

The value W1 of each room 4A, 4B that can be taken when it is determined “N” in step S644 is greater than the fourth heating threshold (for example, −3.0 ° C.) and the fifth heating threshold (for example, +3). The temperature is less than 0.0 ° C. and is distributed over a relatively wide range. For example, when the value W1 of each of the rooms 4A and 4B is distributed in a biased manner toward + 3.0 ° C. (that is, the advantageous side from the set temperature), the air volume of the first floor fan 10Ba is the third air volume (for example, 400 m ^If set to ³ / h) (step S650), there is a possibility that the rooms 4A and 4B are heated more than necessary. For this reason, it is desirable that the supply amount of warm air and the air volume of the first-floor fan 10Ba are finely adjusted based on the distribution tendency of the values W1 of the living rooms 4A and 4B.

  FIG. 33 is a flowchart showing a processing procedure of a first-floor room area adjustment step according to another embodiment of the present invention. In the first-floor room area adjustment step S631 of this embodiment, if “N” is determined in step S644, the first-floor room adjustment step S646 and the fan air volume adjustment step S650 shown in FIG. Living room area fine adjustment step S930 is performed. FIG. 34 is a flowchart showing the procedure of the first-floor room area fine adjustment step S930. FIG. 35 is a diagram illustrating the range of the value W1 of each of the living rooms 4A and 4B in the first floor living room area fine adjustment step S930.

  In the first-floor room area fine adjustment step S930 of this embodiment, first, the value W1 of all the rooms included in the first-floor room area A1 (the first-floor rooms 4A and 4B in the present embodiment) is the smallest. It is determined whether or not the minimum value W2s is greater than a fourth heating threshold value (for example, −3.0 ° C.) and the maximum value W2m is less than a sixth heating threshold value (for example, + 0.5 ° C.) (step). S931). Note that the fourth heating threshold is a constant used in step S643 (shown in FIG. 33). The sixth heating threshold is a constant used for the determination in the efficiency operation step S624 (shown in FIG. 31).

  As shown in FIG. 35, when the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.) and the maximum value W2m is less than the sixth heating threshold (for example, + 0.5 ° C.). (“Y” in step S931), the values W1 of the living rooms 4A and 4B are distributed in a biased direction at −3.0 ° C. (that is, disadvantageous from the set temperature) (in FIG. 35, “C1”). ). Moreover, the value W1 of each room 4A, 4B has a region that does not overlap with the threshold range (below -1.5 ° C to greater than + 1.5 ° C) in the second room supply amount adjustment step S646 (shown in FIG. 12). include. In such a case, it is desirable that the supply amount of warm air in each of the rooms 4A and 4B is adjusted with a threshold value that deviates from the set temperature toward the disadvantage side (that is, −3.0 ° C.). In this embodiment, the fifth living room supply amount adjustment step S932 is performed.

  FIG. 36 is a flowchart illustrating an example of the processing procedure of the fifth room supply amount adjustment step S932. The range of the threshold value in the fifth room supply amount adjustment step S932 is, for example, “+ 0.5 ° C. (less than) to −0.5 ° C. (above)”, “−0.5 ° C. (less than) to −1.5. “° C. (above)” and “less than −1.5 ° C.”. Thus, the threshold value in the fifth room supply amount adjustment step S932 is different from the threshold value in the second room supply amount adjustment step S646 (shown in FIG. 12), which is disadvantageous from the set temperature (that is, −3.0 ° C.). Side).

  In the fifth room supply amount adjustment step S932, the opening degree of the damper 20 is set to be larger in the room 4A or the room 4B where the value W1 is smaller (steps S942 to S944). Thereby, since more warm air (mixed air) is supplied to room 4A, 4B where temperature is low, it can be heated efficiently. For example, the smallest first opening is set for the damper 20 of the living room 4A or 4B having the value W1 of + 0.5 ° C. (less than) to −0.5 ° C. (above) (step S942). The damper 20 of the living room 4A or 4B having the value W1 of −0.5 ° C. (less than) to −1.5 ° C. (or higher) is set to a third opening larger than the first opening (step S943). . The damper 20 of the living room 4A or 4B having the value W1 of less than −1.5 ° C. is set to the fifth opening that is larger than the third opening (step S944). As described above, in the fifth room supply amount adjustment step S932, the largest fifth opening is started from the smallest first opening based on the threshold value biased from the set temperature to the disadvantage side (that is, -3.0 ° C side). Each room 4A, 4B can be effectively heated because it is set evenly.

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (1st floor living room 4A and 4B in this embodiment) of 1st floor living room area A1 was adjusted (step S945). When it is determined that the opening degree of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 has been adjusted (“Y” in step S945), the series of processes in the fifth room supply amount adjustment step S932 is completed. To do. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first floor living room area A1 are not adjusted ("N" in step S945), the other living rooms 4A in the first floor living room area A1 Alternatively, the damper 20 of the living room 4B is selected (step S946), and steps S941 to S945 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and the living rooms 4B in the first floor living room area A1 is adjusted based on the value W1, the warm air (mixed air) to the living rooms 4A and 4B is adjusted. The supply amount can be adjusted individually.

  As shown in FIG. 34, in the first-floor room area fine adjustment step S930, the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.), and the maximum value W2m is the sixth heating threshold (for example, , + 0.5 ° C.) (“N” in step S931), the next step S933 is performed. In step S933, it is determined whether the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.). Is done. Note that the third heating threshold is a constant used in step S622 to determine whether or not active operation is necessary. The fifth heating threshold is a constant used in step S644 (shown in FIG. 33).

  As shown in FIG. 35, when the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.). (“Y” in step S933), the values W1 of the living rooms 4A and 4B are distributed in a biased direction toward + 3.0 ° C. (that is, the advantageous side from the set temperature) (“C2” in FIG. 35). . Moreover, the value W1 of each room 4A, 4B has a region that does not overlap with the threshold range (below -1.5 ° C to greater than + 1.5 ° C) in the second room supply amount adjustment step S646 (shown in FIG. 12). include. In such a case, it is desirable that the supply amount of warm air in each of the living rooms 4A and 4B is adjusted with a threshold value that deviates from the set temperature toward the advantageous side (that is, + 3.0 ° C.). In this embodiment, the sixth living room supply amount adjustment step S934 is performed.

  FIG. 37 is a flowchart illustrating an example of the processing procedure of the sixth living room supply amount adjustment step S934. The threshold ranges in the sixth room supply amount adjustment step S934 are, for example, “+ 1.5 ° C. (above)”, “+ 1.5 ° C. (less than) to + 0.5 ° C. (above)”, and “+0. 5 ° C. (less than) to −0.5 ° C. (greater than) ”. As described above, the threshold value in the sixth room supply amount adjustment step S934 is set so as to be biased toward the advantageous side (that is, + 3.0 ° C. side) from the set temperature.

  In the sixth room supply amount adjustment step S934, the opening degree of the damper 20 is set to be larger in the room 4A or the room 4B where the value W1 is smaller (steps S952 to S954). Thereby, since more warm air (mixed air) is supplied to room 4A, 4B where temperature is low, it can be heated efficiently. For example, the smallest first opening degree is set for the damper 20 in the room 4A or the room 4B where the value W1 is + 1.5 ° C. (or higher) (step S952). The damper 20 of the living room 4A or the living room 4B having the value W1 of + 1.5 ° C. (less than) to + 0.5 ° C. (or higher) is set to a third opening larger than the first opening (step S953). The damper 20 of the living room 4A or the living room 4B having the value W1 of + 0.5 ° C. (less than) to −0.5 ° C. (greater) is set to a fifth opening larger than the third opening (step S954). ). Thus, the sixth room supply amount adjustment step S934 is based on the threshold deviating from the set temperature to the advantageous side (ie, + 3.0 ° C.), from the smallest first opening to the largest fifth opening. Therefore, the living rooms 4A and 4B can be effectively heated.

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in this embodiment, the living room 4A and the living room 4B) in the first floor living room area A1 has been adjusted (step S955). When it is determined that the opening degree of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 has been adjusted (“Y” in step S955), the series of processes in the sixth room supply amount adjustment step S934 is completed. To do. On the other hand, when it is determined that the opening degree of the dampers 20 of all the living rooms 4A and 4B in the first floor living room area A1 is not adjusted ("N" in step S955), the other living rooms 4A in the first floor living room area A1 Alternatively, the damper 20 of the living room 4B is selected (step S956), and steps S951 to S955 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B in the first floor living room area A1 is adjusted based on the value W1, supply of warm air (mixed air) to the respective living rooms 4A and 4B The amount can be adjusted effectively.

  As shown in FIG. 34, in step S933 of the first-floor room area fine adjustment step S930, the minimum value W2s is larger than the third heating threshold (for example, −0.5 ° C.), and the maximum value W2m is the fifth heating. When it is determined that it is not less than a threshold value (for example, + 3.0 ° C.) (“N” in step S933), as shown in FIG. 35, the values W1 of the respective rooms 4A and 4B are −3.0 ° C. to The distribution is biased to both −0.5 ° C. (that is, the disadvantageous side from the set temperature) and + 0.5 ° C. to + 3.0 ° C. (that is, the advantageous side from the set temperature). C3 "). Moreover, the value W1 of each room 4A, 4B is the threshold range (−3.0 ° C. to + 0.5 ° C.) of the fifth room supply amount adjustment step S932 (shown in FIG. 36) or the sixth room supply amount adjustment. It is wider than the threshold range (−0.5 ° C. to + 3.0 ° C.) in step S934 (shown in FIG. 37). Therefore, it is desirable that the supply amount of warm air in each of the living rooms 4A and 4B is adjusted based on the second living room supply amount adjustment step S646 (shown in FIG. 12).

  Next, as shown in FIG. 34, in the first-floor room area fine adjustment step S930, the air volume of the fan 10B (first-floor fan 10Ba) in the first-floor room area A1 is adjusted (fan air volume adjustment steps S935 to S937). . In the fan air volume adjustment steps S935 to S937, the air volume of the first floor fan 10Ba is adjusted based on the value W1 (a value obtained by subtracting the target temperature from the temperature of the room 4A or the room 4B of the first floor room area A1).

In step S931, when the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.) and the maximum value W2m is less than the sixth heating threshold (for example, + 0.5 ° C.) (in step S931). , “Y”), the value W1 of each of the rooms 4A and 4B is distributed to the −3.0 ° C. side (that is, the disadvantageous side from the set temperature) (“C1” in FIG. 35). For this reason, it is effective to increase the air volume of the first-floor fan 10Ba and actively supply warm air to the first-floor room area A1 including the low-temperature room 4A or the room 4B. Therefore, as shown in FIG. 34, the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S935).

When it is determined in step S933 that the minimum value W2s is greater than the third heating threshold value (for example, −0.5 ° C.) and the maximum value W2m is less than the fifth heating threshold value (for example, + 3.0 ° C.). (“Y” in step S933), the values W1 of the living rooms 4A and 4B are distributed in a biased direction toward + 3.0 ° C. (that is, the advantageous side from the set temperature) (“C2” in FIG. 35). . For this reason, it is desirable to save energy by making the air volume of the first-floor fan 10Ba smaller than the fan air volume adjusting step S935. Therefore, as shown in FIG. 34, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S936).

When it is determined in step S933 that the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is not less than the fifth heating threshold (for example, + 3.0 ° C.) ( In step S933, “N”), the values W1 of the respective rooms 4A and 4B are −3.0 ° C. to −0.5 ° C. (that is, the disadvantageous side from the set temperature), and + 0.5 ° C. to + 3.0 ° C. The distribution is biased toward both of the degrees Celsius (that is, the advantageous side from the set temperature) ("C3" in FIG. 35). Therefore, as shown in FIG. 34, the air volume of the first-floor fan 10Ba is an intermediate air volume between the second air volume in the fan air volume adjusting step S936 and the fourth air volume in the fan air volume adjusting step S935 (third air volume (for example, , 400 m ³ / h)) (fan air volume adjustment step S937). After the processing of the fan air volume adjustment steps S935 to S937 is completed, the series of processing of the first-floor room area fine adjustment step S930 is completed.

  Thus, in the first floor room area fine adjustment step S930, when it is determined that the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S644), Based on the distribution tendency of the values W1 of the living rooms 4A and 4B, the supply amount of warm air and the air volume of the first-floor fan 10Ba are finely adjusted. Each of the living rooms 4A and 4B can be effectively heated by such a first-floor room fine adjustment step S930.

  In the first-floor room area adjustment step S631 of this embodiment, fan air volume adjustment steps S647 to S649 (shown in FIG. 33) and fan air volume adjustment steps S935 to S937 (shown in FIG. 34) are performed in the first-floor room area A1. It adjusts so that the air volume of 1st floor fan 10Ba becomes large, so that the average value of value W1 of living room 4A, 4B is small.

As shown in FIG. 33, when it is determined in step S644 that the maximum value W2m of the first-floor room area A1 is not less than the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S644). ), It is considered that the values W1 of the living rooms 4A and 4B are distributed to the + 3.0 ° C. side (that is, the advantageous side from the set temperature). For this reason, the average value of the values W1 of the rooms 4A and 4B in the first-floor room area A1 is considered to be the largest. In this case, in the fan air volume adjustment step S649, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h).

As shown in FIG. 34, in step S933, the minimum value W2s is larger than the third heating threshold (for example, −0.5 ° C.), and the maximum value W2m is the fifth heating threshold (for example, + 3.0 ° C.). When it is determined that the temperature is less than (“Y” in step S933), the values W1 of the respective rooms 4A and 4B are distributed to the + 3.0 ° C. side (that is, the advantageous side from the set temperature). However, the bias is smaller than when “Y” is determined in step S644 (shown in FIG. 33). For this reason, it is considered that the average value of the values W1 of the rooms 4A and 4B in the first-floor room area A1 is the same as or slightly smaller than the average value of the values W1 when “Y” is determined in step S644. In this case, in the fan air volume adjustment step S936, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h).

When it is determined in step S933 that the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is not less than the fifth heating threshold (for example, + 3.0 ° C.) ( In step S933, “N”), the values W1 of the respective rooms 4A and 4B are −3.0 ° C. to −0.5 ° C. (that is, the disadvantageous side from the set temperature), and + 0.5 ° C. to + 3.0 ° C. The distribution is biased to both degrees Celsius (that is, from the set temperature to the advantageous side). For this reason, it is considered that the average value of the values W1 of the living rooms 4A and 4B in the first-floor room area A1 is smaller than the average value of the values W1 when “Y” is determined in step S933. In this case, in the fan air volume adjustment step S937, the air volume of the first-floor fan 10Ba is set to the third air volume (for example, 400 m ³ / h).

In step S931, when the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.) and the maximum value W2m is less than the sixth heating threshold (for example, + 0.5 ° C.) (in step S931). , “Y”), the values W1 of the respective rooms 4A, 4B are distributed to the −3.0 ° C. side (that is, the disadvantageous side from the set temperature). For this reason, it is considered that the average value W1 of the rooms 4A and 4B in the first-floor room area A1 is smaller than the average value of the values W1 when “N” is determined in step S933. In this case, in the fan air volume adjustment step S935, the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

As shown in FIG. 33, when it is determined in step S643 that the minimum value W2s of the first-floor room area A1 is equal to or lower than the fourth heating threshold (for example, −3.0 ° C.) (in step S643, “Y ”), Compared with the case where“ Y ”is determined in step S931, the values W1 of the respective rooms 4A and 4B are distributed to the −3.0 ° C. side (that is, the disadvantageous side from the set temperature). . For this reason, it is considered that the average value of the values W1 of the living rooms 4A and 4B in the first-floor room area A1 is the same as or slightly smaller than the average value of the values W1 when “Y” is determined in step S931. In this case, in the fan air volume adjustment step S648, the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

When it is determined in step S641 that the maximum value W2m of the value W1 of the first-floor room area A1 is equal to or less than the first heating threshold (for example, -1.5 ° C.) (“Y” in step S641), step Compared with the case where “Y” is determined in S643, it is considered that the values W1 of the respective rooms 4A and 4B are distributed to the −3.0 ° C. side (that is, the disadvantageous side from the set temperature). For this reason, it is considered that the average value of the values W1 of the rooms 4A and 4B in the first-floor room area A1 is the same as or slightly smaller than the average value of the values W1 when “Y” is determined in step S643. In this case, in the fan air volume adjustment step S647, the air volume of the first floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

  As described above, the fan air volume adjustment steps S647 to S649 (shown in FIG. 33) and the fan air volume adjustment steps S935 to S937 (shown in FIG. 34) of this embodiment are performed in the rooms 4A and 4B in the first floor room area A1. Since the air volume of the first-floor fan 10Ba is adjusted so that the average value of the value W1 is smaller, the rooms 4A and 4B in the first-floor room area A1 can be efficiently heated.

  FIG. 38 is a flowchart showing the processing procedure of the second-floor room area adjustment step according to another embodiment of the present invention. Similarly to the first-floor room area adjustment step S631 (shown in FIG. 33), the second-floor room area adjustment step S632 of this embodiment is also changed to the second room supply amount adjustment step S656 and the fan air volume adjustment step S660 shown in FIG. Instead, the second-floor room area fine adjustment step S960 is preferably performed. FIG. 39 is a flowchart showing the procedure of the second-floor room area fine adjustment step S960.

  The second-floor room fine-tuning step S960 of this embodiment is the smallest among the values W1 of all the rooms included in the second-floor room area A2 (the second-floor rooms 4C and 4D in this embodiment). It is determined whether or not the minimum value W3s is greater than the fourth heating threshold (for example, −3.0 ° C.) and the maximum value W3m is less than the sixth heating threshold (for example, + 0.5 ° C.) ( Step S961).

  As shown in FIG. 35, when the minimum value W2s is larger than the fourth heating threshold (for example, −3.0 ° C.) and the maximum value W3m is less than the sixth heating threshold (for example, + 0.5 ° C.). ("Y" in step S961), the values W1 of the respective rooms 4C, 4D are distributed in a biased manner to the -3.0 ° C side (that is, the disadvantageous side from the set temperature) (in FIG. 35, "C1 "). For this reason, the fifth room supply amount adjustment step S962 in which a threshold value that is deviated from the set temperature toward the disadvantage side (ie, −3.0 ° C.) is performed.

  The fifth room supply amount adjustment step S962 is the same processing procedure as the fifth room supply amount adjustment step S932 (shown in FIG. 36) in the first floor living room area fine adjustment step S930. Thereby, the opening degree of the dampers 20 of all the living rooms 4C and 4D in the second-floor room area A2 is adjusted based on the value W1 of each of the living rooms 4C and 4D distributed to the disadvantage side from the set temperature. The supply amount of warm air (mixed air) to the living rooms 4C and 4D can be effectively adjusted.

  As shown in FIG. 39, in the second-floor room area fine adjustment step S960, the minimum value W3s is larger than the fourth heating threshold (for example, −3.0 ° C.), and the maximum value W3m is the sixth heating threshold (for example, , + 0.5 ° C.) (“N” in step S961), the next step S963 is performed. In step S963, it is determined whether or not the minimum value W3s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W3m is less than the fifth heating threshold (for example, + 3.0 ° C.). Is done.

  As shown in FIG. 35, the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.). When it is determined (“Y” in step S963), the values W1 of the respective rooms 4C and 4D are distributed to be biased toward the + 3.0 ° C. side (that is, the advantageous side from the set temperature) (in FIG. 35). , “C2”). For this reason, the sixth room supply amount adjustment step S964 in which a threshold value that is biased toward the advantageous side (that is, + 3.0 ° C.) from the set temperature is set is performed.

  The sixth room supply amount adjustment step S964 is the same processing procedure as the sixth room supply amount adjustment step S934 (shown in FIG. 37) in the first floor living room area fine adjustment step S930. Accordingly, the opening degrees of the dampers 20 of all the living rooms 4C and 4D in the second-floor room area A2 are adjusted based on the values W1 of the living rooms 4C and 4D that are distributed in an advantageous manner from the set temperature. The supply amount of warm air (mixed air) to the living rooms 4C and 4D can be effectively adjusted.

  As shown in FIG. 39, in step S963 of the second-floor room area fine adjustment step S960, the minimum value W3s is larger than the third heating threshold (for example, −0.5 ° C.), and the maximum value W3m is the fifth heating. When it is determined that it is not less than the threshold value (for example, + 3.0 ° C.) (“N” in step S963), the values W1 of the respective rooms 4C and 4D are −3.0 ° C. to −0.5 ° C. (that is, The distribution is biased toward both of + 0.5 ° C. to + 3.0 ° C. (that is, the advantageous side from the set temperature) (“C3” in FIG. 35). For this reason, in this embodiment, 2nd living room supply amount adjustment step S646 (shown in FIG. 12) is implemented. Accordingly, the living rooms 4C and 4D can be efficiently heated.

  Next, in the second-floor room area fine adjustment step S960, the air volume of the fan 10B (second-floor fan 10Bb) in the second-floor room area A2 is adjusted (fan air volume adjustment steps S965 to S967). In the fan air volume adjustment steps S965 to S967, the air volume of the first-floor fan 10Ba is adjusted based on the value W1 of each of the rooms 4C and 4D.

The fan air volume adjustment steps S965 to S967 are the same processing procedure as the fan air volume adjustment steps S935 to S937 in the first-floor room area fine adjustment step S930 shown in FIG. That is, when the minimum value W2s is larger than the fourth heating threshold value (for example, −3.0 ° C.) and the maximum value W3m is smaller than the sixth heating threshold value (for example, + 0.5 ° C.) in step S961 (step S961). In S961, “Y”), the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S965).

When it is determined in step S963 that the minimum value W2s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W2m is less than the fifth heating threshold (for example, + 3.0 ° C.). (“Y” in step S963) The air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S966). When it is determined in step S963 that the minimum value W3s is greater than the third heating threshold (for example, −0.5 ° C.) and the maximum value W3m is not less than the fifth heating threshold (for example, + 3.0 ° C.) ( In step S963, “N”), the air volume of the first-floor fan 10Ba is set to the third air volume (for example, 400 m ³ / h) (fan air volume adjustment step S967). After the process of fan air volume adjustment steps S965 to S967 is completed, a series of processes of the second-floor room fine adjustment step S960 is completed.

  Thus, in the second-floor room area fine adjustment step S960, when it is determined that the maximum value W3m is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S644), Based on the distribution tendency of the values W1 of the living rooms 4C and 4D, the supply amount of warm air and the air volume of the second-floor fan 10Bb are finely adjusted. Each of the living rooms 4C and 4D can be effectively heated by such a second-floor room fine adjustment step S960.

  In fan air volume adjustment steps S657 to S659 (shown in FIG. 38) and fan air volume adjustment steps S965 to S967 (shown in FIG. 39), fan air volume adjustment steps S647 to S649 (in FIG. 33) of the first-floor room area adjustment step S631. And the fan air volume adjustment steps S935 to S937 (shown in FIG. 34), the smaller the average value of the values W1 of the rooms 4C and 4D of the second-floor room area A2, the larger the airflow of the second-floor fan 10Bb. Adjusted to be. For this reason, room 4C and 4D of 2nd floor room area A2 can be heated efficiently.

  FIG. 40 is a flowchart showing the processing procedure of the first-floor room area adjustment step S831 of the cooling step S335 according to another embodiment of the present invention. The first-floor room area adjustment step S831 of this embodiment is the same as that of the first-floor room area adjustment step S631 (shown in FIG. 33) of the heating step S235 (all implementations included in the first-floor room area A1). In the embodiment, the smallest minimum value W6s among the values W5 of the first-floor rooms 4A and 4B) is greater than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S844). ), Instead of the fourth room supply amount adjustment step S846 and the fan air volume adjustment step S850 shown in FIG. 24, a first-floor room area fine adjustment step S970 is performed. The first-floor room area fine adjustment step S970 is a step for finely adjusting the supply amount of cold air and the air volume of the first-floor fan 10Ba based on the distribution tendency of the values W5 of the respective rooms 4A and 4B. . FIG. 41 is a flowchart showing the procedure of the first-floor room area fine adjustment step S970.

  In the first floor living room area fine adjustment step S970 of this embodiment, first, the value W5 of all the living rooms included in the first floor living room area A1 (the first floor living rooms 4A and 4B in this embodiment) is the smallest. It is determined whether or not the minimum value W6s is larger than a sixth cooling threshold value (for example, −0.5 ° C.) and the maximum value W6m is smaller than a fourth cooling threshold value (+ 3.0 ° C.) (step). S971). The fourth cooling threshold is a constant used in step S843 (shown in FIG. 40). The sixth cooling threshold is a constant used for the determination in step S825 (shown in FIG. 32).

  As shown in FIG. 35, when the minimum value W6s is greater than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W6m is less than the fourth cooling threshold (for example, + 3.0 ° C.). ("Y" in step S971), the values W5 of the respective rooms 4A, 4B are distributed in a biased direction to + 3.0 ° C. (that is, disadvantageous from the set temperature) (“C2” in FIG. 35). . In addition, the value W5 of each room 4A, 4B has a region that does not overlap with the threshold range (below -1.5 ° C to greater than + 1.5 ° C) in the fourth room supply amount adjustment step S846 (shown in FIG. 24). include. In such a case, it is desirable that the supply amount of the cold air in each of the rooms 4A and 4B is adjusted with a threshold value that is deviated from the set temperature to the disadvantage side (ie, + 3.0 ° C.). In this embodiment, the seventh room supply amount adjustment step S972 is performed.

  FIG. 42 is a flowchart illustrating an example of a processing procedure of the seventh living room supply amount adjustment step S972. The range of the threshold in the seventh room supply amount adjustment step S972 is, for example, “−0.5 ° C. (greater than) to + 0.5 ° C. (less than)”, “+ 0.5 ° C. (above) to + 1.5 ° C. (Below) and “greater than + 1.5 ° C.”. As described above, the threshold value in the seventh room supply amount adjustment step S972 is different from the threshold value in the fourth room supply amount adjustment step S846 (shown in FIG. 24), which is disadvantageous from the set temperature (ie, + 3.0 ° C. side). ).

  In the seventh room supply amount adjustment step S972, the opening degree of the damper 20 is set to be larger as the room 4A or the room 4B has a larger value W5 (steps S982 to S984). Thereby, since more cold air (mixed air) is supplied to the living rooms 4A and 4B having a higher temperature, the air can be efficiently cooled. For example, the smallest first opening degree is set for the damper 20 in the living room 4A or the living room 4B having the value W1 of −0.5 ° C. (greater than) to + 0.5 ° C. (less than) (step S982). The damper 20 of the room 4A or the room 4B having the value W5 of + 0.5 ° C. (above) to + 1.5 ° C. (below) is set to a third opening larger than the first opening (step S983). The damper 20 of the living room 4A or the living room 4B having the value W5 larger than + 1.5 ° C. is set to the fifth opening that is larger than the third opening (step S984). In this way, in the seventh living room supply amount adjustment step S972, the smallest first opening degree to the largest fifth opening degree based on the threshold value that deviates from the set temperature to the disadvantage side (that is, + 3.0 ° C. side). Therefore, the living rooms 4A and 4B can be effectively cooled.

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in this embodiment, living room 4A, 4B) of 1st floor room area A1 was adjusted (step S985). When it is determined that the opening degrees of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 have been adjusted (“Y” in step S985), the series of processes in the seventh room supply amount adjustment step S972 is completed. To do. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first floor living room area A1 are not adjusted ("N" in step S985), the other living rooms 4A in the first floor living room area A1 Alternatively, the damper 20 of the living room 4B is selected (step S986), and steps S981 to S985 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B in the first floor living room area A1 is adjusted based on the value W1, supply of cold air (mixed air) to each of the living rooms 4A and 4B. The amount can be adjusted effectively.

  As shown in FIG. 41, in the first-floor room area fine adjustment step S970, the minimum value W6s is larger than the sixth cooling threshold (for example, −0.5 ° C.), and the maximum value W6m is the fourth cooling threshold (for example, , + 3.0 ° C.) (“N” in step S971), the next step S973 is performed. In step S973, it is determined whether or not the minimum value W6s is greater than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W6m is less than the third cooling threshold (for example, + 0.5 ° C.). Is done. Note that the third cooling threshold is a constant used in step S822 to determine whether or not active operation is necessary. The fifth cooling threshold is a constant used in step S844 (shown in FIG. 40).

  As shown in FIG. 35, when the minimum value W6s is larger than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W6m is less than the third cooling threshold (for example, + 0.5 ° C.). (“Y” in step S973), the values W1 of the living rooms 4A and 4B are distributed in a biased direction at −3.0 ° C. (that is, the advantageous side from the set temperature) (in FIG. 35, “C1”). ). In addition, the value W5 of each room 4A, 4B has a region that does not overlap with the threshold range (below -1.5 ° C to greater than + 1.5 ° C) in the fourth room supply amount adjustment step S846 (shown in FIG. 24). include. In such a case, it is desirable that the supply amount of the cold air in each of the living rooms 4A and 4B is adjusted with a threshold value that is biased toward the advantageous side (that is, −3.0 ° C.) from the set temperature. In this embodiment, the eighth living room supply amount adjustment step S974 is performed.

  FIG. 43 is a flowchart showing an example of the processing procedure of the eighth living room supply amount adjustment step S974. The threshold ranges in the eighth room supply amount adjustment step S974 are, for example, “−1.5 ° C. (below)”, “−1.5 ° C. (greater) to −0.5 ° C. (below)”, and , “−0.5 ° C. (greater than) to −0.5 ° C. (less than)”. As described above, the threshold value in the eighth room supply amount adjustment step S974 is set so as to deviate from the set temperature toward the advantageous side (ie, −3.0 ° C.).

  In the eighth room supply amount adjustment step S974, the opening degree of the damper 20 is set to be larger for the room 4A or the room 4B having a larger value W5 (steps S992 to S994). Thereby, since more cold air (mixed air) is supplied to the living rooms 4A and 4B having a higher temperature, the air can be efficiently cooled. For example, the smallest first opening degree is set for the damper 20 of the living room 4A or the living room 4B having the value W5 of −1.5 ° C. (below) (step S992). The damper 20 of the room 4A or the room 4B having the value W1 of −1.5 ° C. (greater than) to −0.5 ° C. (below) is set to a third opening larger than the first opening (step) S993). The damper 20 of the living room 4A or the living room 4B having the value W5 of −0.5 ° C. (greater than) to −0.5 ° C. (less than) is set to a fifth opening that is larger than the third opening (step). S994). As described above, the eighth room supply amount adjustment step S974 is performed based on the threshold value biased toward the advantageous side (ie, −3.0 ° C. side) from the set temperature, from the smallest first opening degree to the largest fifth opening degree. Each room 4A, 4B can be effectively cooled because it is set evenly.

  And it is judged whether the opening degree of the damper 20 (20a or 20b) of all the living rooms (in this embodiment, living room 4A, 4B) of 1st floor room area A1 was adjusted (step S995). When it is determined that the opening degrees of the dampers 20 of all the living rooms 4A and 4B in the first-floor room area A1 have been adjusted ("Y" in step S995), the series of processes in the eighth room supply amount adjustment step S974 is completed. To do. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A and 4B in the first floor living room area A1 are not adjusted ("N" in step S995), the other living rooms 4A in the first floor living room area A1 Alternatively, the damper 20 of the living room 4B is selected (step S996), and steps S991 to S995 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A and 4B of the first floor living room area A1 is adjusted based on the value W5, supply of cold air (mixed air) to the respective living rooms 4A and 4B The amount can be adjusted effectively.

  As shown in FIG. 41, in step S973 of the first-floor room area fine adjustment step S970, the minimum value W6s is greater than the fifth cooling threshold (for example, −3.0 ° C.), and the maximum value W6m is the third cooling. When it is determined that it is not less than the threshold (for example, + 0.5 ° C.) (“N” in step S973), as shown in FIG. 35, the values W5 of the respective rooms 4A and 4B are −3.0 ° C. to The distribution is biased to both −0.5 ° C. (that is, the advantageous side from the set temperature) and + 0.5 ° C. to + 3.0 ° C. (that is, the disadvantageous side from the set temperature). C3 "). Moreover, the value W5 of each living room 4A, 4B is the threshold value range (−0.5 ° C. to + 3.0 ° C.) of the seventh living room supply amount adjustment step S972 (shown in FIG. 42) or the eighth living room supply amount adjustment. It is wider than the threshold range (−3.0 ° C. to + 0.5 ° C.) in step S974 (shown in FIG. 43). Therefore, it is desirable to adjust the supply amount of cold air in each of the living rooms 4A and 4B based on the fourth living room supply amount adjustment step S846 (shown in FIG. 24).

  Next, as shown in FIG. 41, in the first-floor room area fine adjustment step S970, the air volume of the fan 10B (first-floor fan 10Ba) in the first-floor room area A1 is adjusted (fan air volume adjustment steps S975 to S977). . In the fan air volume adjustment steps S975 to S977, the air volume of the first floor fan 10Ba is adjusted based on the value W5 (the value obtained by subtracting the target temperature from the temperature of the room 4A or the room 4B of the first floor room area A1).

In step S971, when the minimum value W6s is larger than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W6m is less than the fourth cooling threshold (for example, + 3.0 ° C.) (in step S971). , “Y”), the value W5 of each of the rooms 4A and 4B is distributed to the + 3.0 ° C. side (that is, the disadvantageous side from the set temperature) (“C2” in FIG. 35). For this reason, it is effective to increase the air volume of the first-floor fan 10Ba and actively supply cold air to the first-floor room area A1 including the high-temperature room 4A or the room 4B. Accordingly, the air volume of the first floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S975).

When it is determined in step S973 that the minimum value W6s is greater than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W6m is less than the third cooling threshold (for example, + 0.5 ° C.). ("Y" in step S973), the values W5 of the respective rooms 4A, 4B are distributed unevenly on the -3.0 ° C side (that is, on the advantageous side from the set temperature) ("C1" in FIG. 35). ). For this reason, it is desirable to save energy by reducing the air volume of the first-floor fan 10Ba rather than the fan air volume adjusting step S975. Accordingly, the air volume of the first floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S976).

When it is determined in step S973 that the minimum value W6s is greater than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W6m is not less than the third cooling threshold (for example, + 0.5 ° C.) ( In step S973, “N”), the value W5 of each of the rooms 4A and 4B is −3.0 ° C. to −0.5 ° C. (that is, the disadvantageous side from the set temperature), and + 0.5 ° C. to + 3.0 ° C. The distribution is biased toward both of the degrees Celsius (that is, the advantageous side from the set temperature) ("C3" in FIG. 35). For this reason, it is set to an intermediate air volume (third air volume (for example, 400 m ³ / h)) between the second air volume in the fan air volume adjusting step S976 and the fourth air volume in the fan air volume adjusting step S975 (fan air volume adjusting step). S977). After the processing of the fan air volume adjustment steps S975 to S977 is completed, a series of processes of the first floor room area fine adjustment step S970 is completed.

  As described above, in the first-floor room area fine adjustment step S970, when it is determined that the minimum value W6s is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S844). Based on the distribution tendency of the values W5 of the living rooms 4A and 4B, the supply amount of the cold air and the air volume of the first-floor fan 10Ba are finely adjusted. By such a first-floor room area fine adjustment step S970, the respective rooms 4A and 4B can be effectively cooled.

  In the first-floor room area adjustment step S831 of this embodiment, fan air volume adjustment steps S847 to S849 (shown in FIG. 40) and fan air volume adjustment steps S975 to S977 (shown in FIG. 41) are performed in the first-floor room area A1. It adjusts so that the air volume of 1st-floor fan 10Ba becomes large, so that the average value of value W5 of living room 4A, 4B is large.

As shown in FIG. 40, when it is determined in step S844 that the minimum value W6s of the first-floor room area A1 is not more than the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S844) It is considered that the value W5 of each of the rooms 4A and 4B is unevenly distributed on the −3.0 ° C. side (that is, on the advantageous side from the set temperature). For this reason, the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is considered to be the smallest. In this case, in the fan air volume adjustment step S849, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h).

As shown in FIG. 41, in step S973, the minimum value W6s is larger than the fifth cooling threshold (for example, −3.0 ° C.), and the maximum value W6m is the third cooling threshold (for example, + 0.5 ° C.). If it is determined that the value is less than “Y” (step S973, “Y”), the values W5 of the living rooms 4A and 4B are distributed unevenly toward the −3.0 ° C. side (that is, the advantageous side from the set temperature). The bias is small compared to the case where “Y” is determined in step S844 (shown in FIG. 40). For this reason, it is considered that the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is the same as or slightly larger than the average value of the values W5 when “Y” is determined in step S844. In this case, in the fan air volume adjustment step S976, the air volume of the first-floor fan 10Ba is set to the second air volume (for example, 250 m ³ / h).

When it is determined in step S973 that the minimum value W6s is greater than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W6m is not less than the third cooling threshold (for example, + 0.5 ° C.) ( In step S973, “N”), the values W1 of the respective rooms 4A and 4B are −3.0 ° C. to −0.5 ° C. (that is, an advantageous side from the set temperature), and + 0.5 ° C. to + 3.0 ° C. The distribution is biased to both degrees Celsius (that is, the disadvantageous side from the set temperature). For this reason, the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is considered to be larger than the average value of the values W5 when determined as “Y” in step S973. In this case, in the fan air volume adjustment step S977, the air volume of the first floor fan 10Ba is set to the third air volume (for example, 400 m ³ / h).

In step S971, when the minimum value W6s is larger than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W6m is less than the fourth cooling threshold (for example, + 3.0 ° C.) (in step S971). , “Y”), the values W5 of the respective rooms 4A and 4B are distributed to the + 3.0 ° C. side (that is, the disadvantageous side from the set temperature). For this reason, the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is considered to be larger than the average value of the values W5 when determined as “N” in step S973. In this case, in the fan air volume adjustment step S975, the air volume of the first-floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

As shown in FIG. 40, when it is determined in step S843 that the maximum value W6m of the first-floor room area A1 is greater than or equal to the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S843). ) Compared with the case where “Y” is determined in step S971, the values W5 of the living rooms 4A and 4B are distributed more on the + 3.0 ° C. side (that is, on the disadvantageous side from the set temperature). For this reason, it is considered that the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is the same as or slightly larger than the average value of the values W5 when “Y” is determined in step S971. In this case, in the fan air volume adjustment step S848, the air volume of the first floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

When it is determined that the minimum value W6s of the value W6 in the first-floor room area A1 is equal to or greater than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S841), “Y” in step S843. Compared to the case where it is determined that the value W5 of each of the rooms 4A and 4B is distributed to the + 3.0 ° C. side (that is, the disadvantageous side from the set temperature). For this reason, it is considered that the average value of the values W5 of the rooms 4A and 4B in the first-floor room area A1 is the same as or slightly larger than the average value of the values W5 when “Y” is determined in step S843. In this case, in the fan air volume adjustment step S647, the air volume of the first floor fan 10Ba is set to the fourth air volume (for example, 550 m ³ / h) which is the maximum air volume.

  As described above, the fan air volume adjustment steps S847 to S849 (shown in FIG. 40) and the fan air volume adjustment steps S975 to S977 (shown in FIG. 41) of this embodiment are performed for the rooms 4A and 4B in the first floor room area A1. As the average value of the value W5 is larger, the air volume of the first-floor fan 10Ba is adjusted to be larger, so that the rooms 4A and 4B in the first-floor room area A1 can be efficiently cooled.

  FIG. 44 is a flowchart showing the processing procedure of the second-floor room area adjustment step in the cooling step S335 according to another embodiment of the present invention. Similarly to the first-floor room area adjustment step S831 (shown in FIG. 40), the second-floor room area adjustment step S832 in this embodiment is also changed to the fourth room supply amount adjustment step S846 and the fan air volume adjustment step S860 shown in FIG. Instead, it is desirable that the second-floor room area fine adjustment step S921 is performed. FIG. 45 is a flowchart showing the procedure of the second-floor room area fine adjustment step S921 according to another embodiment of the present invention.

  The second-floor room fine-tuning step S921 of this embodiment is first the smallest among the values W5 of all the rooms (second-floor rooms 4C and 4D in this embodiment) included in the second-floor room area A2. It is determined whether or not the minimum value W7s is larger than the sixth cooling threshold value (for example, −0.5 ° C.) and the maximum value W7m is smaller than the fourth cooling threshold value (+ 3.0 ° C.) (step). S922).

  As shown in FIG. 35, when the minimum value W7s is larger than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W7m is less than the fourth cooling threshold (+ 3.0 ° C.). ("Y" in step S922), the value W5 of each of the rooms 4C, 4D is distributed to be biased toward + 3.0 ° C (that is, disadvantageous from the set temperature) ("C2" in FIG. 35). ). For this reason, the seventh room supply amount adjustment step S923 in which a threshold value biased from the set temperature toward the disadvantage side (that is, + 3.0 ° C.) is set is performed.

  The seventh room supply amount adjustment step S923 is the same processing procedure as the seventh room supply amount adjustment step S972 (shown in FIG. 42) of the first floor living room area fine adjustment step S970. Thereby, the opening degree of the dampers 20 of all the living rooms 4C and 4D in the second-floor room area A2 is adjusted based on the value W5 of each of the living rooms 4C and 4D that is distributed to the disadvantage side from the set temperature. Therefore, the supply amount of cold air (mixed air) to each of the living rooms 4C and 4D can be adjusted effectively.

  As shown in FIG. 45, it is determined that the minimum value W7s is larger than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W7m is not less than the fourth cooling threshold (+ 3.0 ° C.). If so ("N" in step S922), the next step S924 is performed. In step S924, the second-floor room area fine adjustment step S921 is such that the minimum value W7s is larger than the fifth cooling threshold value (for example, -3.0 ° C) and the maximum value W7m is the third cooling threshold value (for example, +0.5). It is judged whether it is less than (C).

  As shown in FIG. 35, when the minimum value W7s is greater than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W7m is less than the third cooling threshold (for example, + 0.5 ° C.). ("Y" in step S924), the value W5 of each of the rooms 4C and 4D is distributed to be deviated toward the -3.0 ° C side (that is, the advantageous side from the set temperature) (in FIG. 35, "C1 "). For this reason, the eighth living room supply amount adjustment step S925 in which a threshold value biased toward the advantageous side (that is, −3.0 ° C.) from the set temperature is performed is performed.

  The eighth living room supply amount adjustment step S974 is the same processing procedure as the eighth living room supply amount adjustment step S974 (shown in FIG. 43) of the first floor living room area fine adjustment step S970. Thereby, the opening degree of the dampers 20 of all the living rooms 4C and 4D in the second-floor room area A2 is adjusted based on the value W5 of each of the living rooms 4C and 4D distributed in an advantageous manner from the set temperature. The amount of cold air (mixed air) supplied to each of the rooms 4C and 4D can be effectively adjusted.

  As shown in FIG. 45, in step S924 of the second-floor room area fine adjustment step S921, the minimum value W7s is larger than the fifth cooling threshold (for example, −3.0 ° C.), and the maximum value W7m is the third cooling. When it is determined that it is not less than the threshold (for example, + 0.5 ° C.) (“N” in step S924), as shown in FIG. 35, the values W5 of the respective rooms 4C, 4D are −3.0 ° C. to The distribution is biased to both −0.5 ° C. (that is, the advantageous side from the set temperature) and + 0.5 ° C. to + 3.0 ° C. (that is, the disadvantageous side from the set temperature). C "). For this reason, in this embodiment, the fourth living room supply amount adjustment step S846 (shown in FIG. 24) is performed. Therefore, each living room 4C, 4D can be efficiently cooled.

  Next, in the second-floor room area fine adjustment step S921, the air volume of the fan 10B (second-floor fan 10Bb) in the second-floor room area A2 is adjusted (fan air volume adjustment steps S926 to S928). In the fan air volume adjustment steps S926 to S928, the air volume of the first floor fan 10Ba is adjusted based on the value W5 (the value obtained by subtracting the target temperature from the temperature of the room 4C or the room 4D of the second floor room area A2).

The fan air volume adjustment steps S926 to S928 are the same processing procedure as the fan air volume adjustment steps S975 to S977 of the first-floor room area fine adjustment step S970 shown in FIG. That is, when the minimum value W7s is larger than the sixth cooling threshold (for example, −0.5 ° C.) and the maximum value W7m is smaller than the fourth cooling threshold (+ 3.0 ° C.) in step S922 (step S922). In S922, “Y”), the air volume of the second-floor fan 10Bb is set to the fourth air volume (for example, 550 m ³ / h) (fan air volume adjustment step S926).

In step S924, when the minimum value W7s is larger than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W7m is less than the third cooling threshold (for example, + 0.5 ° C.) (in step S924). , “Y”), the air volume of the second-floor fan 10Bb is set to the second air volume (for example, 250 m ³ / h) (fan air volume adjustment step S927). In step S924, when the minimum value W7s is larger than the fifth cooling threshold (for example, −3.0 ° C.) and the maximum value W7m is not less than the third cooling threshold (for example, + 0.5 ° C.) (in step S924, “N”) The air volume of the second-floor fan 10Bb is set to the third air volume (for example, 400 m ³ / h) (fan air volume adjustment step S928). After the processing of the fan air volume adjustment steps S926 to S928 is completed, the series of processing of the second-floor room area fine adjustment step S921 is completed.

  As described above, in the second-floor room area fine adjustment step S921, when the minimum value W7s is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S854), each of the living rooms 4C, Based on the distribution tendency of the 4D value W5, the supply amount of the cold air and the air volume of the second-floor fan 10Bb are finely adjusted. By such a second-floor room area fine adjustment step S921, each of the rooms 4C and 4D can be effectively cooled.
