Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 conceptually shows a cross-sectional view of a building B in which a building air conditioning method according to an embodiment of the present invention (hereinafter simply referred to as “air conditioning method”) is implemented. As shown in FIG. 1, in this embodiment, a house Bh is shown as a building B. 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 4C and a non-living room 4D such as a washroom and a toilet.

  The ventilation air conditioning system 2 is used for the air conditioning method of this embodiment. The ventilation air conditioning system 2 supplies a basic air inlet 8 for introducing outside air into the underfloor space 3, a chamber box 9 disposed in the underfloor space 3, and air in the chamber box 9 to each of the living rooms 4A to 4C. And a ventilating means 10 that can be used. The air in the chamber box 9 may be directly supplied to the non-living room 4D. Furthermore, in the ventilation air conditioning system 2 of this embodiment, what includes the heat collecting device 22 is shown, but this device is an optional element.

  The base air supply port 8 is one opening provided at the rising portion of the base 5. Outside air is taken into the underfloor space 3 through the basic air supply port 8. In the present embodiment, in order to positively introduce outside air, for example, a basic air supply fan 11 is provided in the vicinity of the basic air supply port 8. The foundation 5 is preferably insulated from the outside air by a heat insulating material such as foamed resin (not shown).

  The outside air supplied to the underfloor space 3 is exchanged with the ground cooling heat via the ground 6 in the underfloor space 3.

For example, the second air volume is set to 600 m ³ / h, which is larger than the first air volume. For example, the third air volume is set to 800 m ³ / h, which is larger than the second air volume. For example, the fourth air volume is set to 1000 m ³ / h, which is larger than the third air volume. Note that the air volume of the fan 10B is not limited to these first to fourth air volumes.

  For example, the air purification device 10C is provided between one end 10Ai and the other end 10Ao of the duct 10A. The air purification device 10C of the present embodiment is provided on the upstream side of the fan 10B.

Further, the fan 10B of the ventilation means 10 is operated. As a result, the underfloor air 17 (outside air) is introduced into the first space 9A of the chamber box 9 from the first inlet 13. Further, the underfloor air 17 in the first space 9A is purified from the exhaust port 14 via the duct 10A and the air purifying device 10C, and then passed through the dampers 20 (20a to 20c) to each of the living rooms 4A, 4B and Supplied to 4C. Further, the air in the living rooms 4A, 4B, and 4C is discharged to the outdoors by an exhaust fan 38 or the like provided in each of the living rooms 4A to 4C or the non-living room 4D. Thereby, each living room 4A, 4B, and 4C is ventilated by the clean external air. A series of processing in these ventilation modes S22 is performed by the control means 26. The air volume of the fan 10B of the ventilation means 10 is set to a first air volume (for example, 175 m ³ / h) set based on the number of ventilations required for the building B. The damper 20 of each living room 4A, 4B or 4C is appropriately selected from the first opening to the fifth opening.

  In the heating mode S23, the warm air warmed by the air conditioner 16 (shown in FIG. 1) is supplied to the living rooms 4A, 4B, and 4C (shown in FIG. 1). FIG. 6 is a flowchart illustrating an example of a processing procedure in the heating mode S23. A series of processes in the heating mode S23 is performed by the control means 26 (shown in FIG. 3).

  In the heating mode S23, first, a target temperature is set (step S230). The target temperature is a temperature that is desired to be maintained in each of the living rooms 4A, 4B, and 4C 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 of this embodiment may be set for each of the rooms 4A, 4B, and 4C, 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 heating mode S23, as shown in FIGS. 1 and 3, the temperatures of the respective rooms 4A, 4B, and 4C are detected (step S231). The temperature of each room 4A, 4B and 4C is detected by the room temperature detection means 25 (25a-25c), respectively. The temperature of each room 4A, 4B, and 4C is transmitted to the control means 26.

  Next, in the heating mode S23, a difference V1 between the temperature of each of the rooms 4A, 4B, and 4C and a predetermined target temperature is obtained (step S232). The difference V1 is obtained for each of the living rooms 4A, 4B, and 4C. The difference V1 in the present embodiment is obtained as a value W1 obtained by subtracting the target temperature from the temperatures of the living rooms 4A, 4B, and 4C. It shows that the temperature of each living room 4A, 4B, and 4C is so large that this value W1 (difference V1) is large.

  Next, in the heating mode S23, it is determined whether or not the value W1 of all the living rooms 4A, 4B, and 4C 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, for example.

  When it is determined that the values W1 of all the living rooms 4A, 4B, and 4C are equal to or higher than a predetermined second heating threshold (for example, + 1.5 ° C.) (“Y” in step S233), all Since the temperatures of the living rooms 4A, 4B, and 4C are higher than the target temperature (for example, 20 ° C.), they 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, 4B, and 4C is less than a predetermined second heating threshold (for example, + 1.5 ° C.) (“N” in step S233), Since all the living rooms 4A, 4B, and 4C are not sufficiently heated, it can be determined that air conditioning (heating) by the air conditioner 16 is necessary. In such a case, a heating step S235 for supplying warm air warmed by the air conditioner 16 to each of the living rooms 4A, 4B, and 4C is executed.

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 air volume of the fan 10B (shown in FIG. 1) of the ventilation means 10 is set. (Step S612). The set air volume of the fan 10B of the present embodiment is set to the first air volume (for example, 175 m ³ / h) based on the number of ventilations required for the building B. In step S612, 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. Thereby, similarly to ventilation mode S22, each living room 4A, 4B, and 4C is ventilated by the clean external air (underfloor air 17). By completing the execution of step S611 and step S612, 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, heating by the air conditioner 16 (shown in FIG. 1) is started (step S620). In step S620 of the present embodiment, first, as shown in FIG. 1, the first space 9A and the second space 9B are communicated by the opening / closing part 9C of the chamber box 9. Further, the air conditioner 16 is operated for heating. Further, the fan 10B of the ventilation means 10 is operated. Thereby, in the first space 9 </ b> A, the air in the underfloor space 3 and the air conditioned by the heating operation of the air conditioner 16 are mixed. The mixed air (warm air) is supplied to the living rooms 4A, 4B, and 4C 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 S620 is omitted.

  Next, in the heating step S235, it is first determined whether or not the smallest minimum value W1s among the values W1 of the respective rooms 4A, 4B, or 4C is equal to or less than a predetermined third heating threshold value. (Step S621). In step S621, 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 value (for example, −0.5 ° C.) (“Y” in step S621), the temperature of the room 4A, 4B, or 4C (shown in FIG. 1) is decreased. . For this reason, the active operation step S622 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 (for example, −0.5 ° C.) (“N” in step S621), the respective rooms 4A, 4B, and 4C are relatively warm. For this reason, the efficient operation step S623 in which the efficient operation of the air conditioner 16 is performed is performed.

  FIG. 9 is a flowchart illustrating an example of a processing procedure of the active operation step S622 of the present embodiment. In the active operation step S622, first, it is determined whether or not the largest maximum value W1m among the values W1 of the respective rooms 4A, 4B, or 4C (shown in FIG. 1) is equal to or less than a predetermined first heating threshold value. Determination is made (step S631). In this step S631, it is determined whether heating is required by maximizing the supply amount of warm air (mixed air) to each of the living rooms 4A, 4B, or 4C. Therefore, it is desirable that the first heating threshold is set smaller than the third heating threshold (for example, −0.5 ° C.) used in the previous step. The 1st heating threshold value of this embodiment is set to -1.5 ° C.

  When the maximum value W1m is equal to or lower than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S631), the temperature of all the living rooms 4A, 4B, or 4C (shown in FIG. 1) is greatly increased. It is falling. For this reason, the supply amount of warm air (mixed air) to each living room 4A, 4B or 4C is set to the maximum (step S632). In this case, the damper 20 (shown in FIG. 1) of each room 4A, 4B, or 4C is set to the largest fifth opening. Thereby, supply_amount | feed_rate of the warm air of each living room 4A, 4B or 4C can be maximized.

  On the other hand, when the maximum value W1m is larger than the first heating threshold (for example, −1.5 ° C.) (“N” in step S631), the temperatures of all the rooms 4A, 4B, or 4C (shown in FIG. 1) are It ’s not a big drop. Therefore, it is effective to efficiently heat each living room 4A, 4B or 4C by individually adjusting the amount of warm air (mixed air) supplied to each living room 4A, 4B or 4C. In this case, after the next step S633 and step S634 are executed, a room supply amount adjustment step for individually adjusting the amount of warm air supplied to each room 4A, 4B, or 4C is performed. The room supply amount adjustment step includes a first room supply amount adjustment step S635 and a second room supply amount adjustment step S636.

  FIG. 10 is a flowchart showing an example of the processing procedure of the first living room supply amount adjustment step S635. FIG. 11 is a flowchart illustrating an example of a processing procedure of the second living room supply amount adjustment step S636. In the first living room supply amount adjustment step S635 and the second living room supply amount adjustment step S636, the dampers 20 of the living rooms 4A, 4B, and 4C are based on the values W1 of the living rooms 4A, 4B, and 4C (shown in FIG. 1). The opening degree (shown in FIG. 1) is adjusted. In the present embodiment, the openings of the dampers 20a, 20b, and 20c are set to be larger in the living rooms 4A, 4B, and 4C where the value W1 is smaller. As a result, more warm air (mixed air) is supplied to the living rooms 4A, 4B, and 4C having lower temperatures, so that the living rooms 4A, 4B, and 4C can be efficiently heated.

  For each of the first to fifth openings, a threshold range of the value W1 is set for each room 4A, 4B, or 4C (shown in FIG. 1). The threshold range in the first room supply amount adjustment step S635 is, for example, “greater than + 3.0 ° C.”, “+ 3.0 ° C. to + 1.0 ° C.”, “+ 1.0 ° C. to −1.0 ° C.” ”,“ −1.0 ° C. to −3.0 ° C. ”, and“ <−3.0 ° C. ”. On the other hand, the threshold ranges in the second room supply amount adjustment step S636 are “greater than + 1.5 ° C.”, “+ 1.5 ° C. to + 0.5 ° C.”, “+ 0.5 ° C. to −0.5 ° C.” ”,“ −0.5 ° C. to −1.5 ° C. ”,“ less than −1.5 ° C. ”. As described above, the first room supply amount adjustment step S635 has a larger threshold range than the second room supply amount adjustment step S636.

  Therefore, the first living room supply amount adjustment step S635 is performed for each of the living rooms 4A, 4B, or 4C, even if the value W1 of each of the living rooms 4A, 4B, or 4C (shown in FIG. 1) is distributed over a wide range. The opening degree of 20c can be adjusted with good balance. The details of the first living room supply amount adjustment step S635 and the second living room supply amount adjustment step S636 will be described later.

  As shown in FIG. 9, in step S633, it is determined whether or not the smallest minimum value W1s among the values W1 of the respective rooms 4A, 4B, or 4C (shown in FIG. 1) is equal to or smaller than the fourth heating threshold value. Is done. If the minimum value W1s is significantly small, there is a high possibility that the values W1 of the respective rooms 4A, 4B, or 4C 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 W1s is equal to or lower than the fourth heating threshold value (for example, −3.0 ° C.) (“Y” in step S633), the value W1 of each living room 4A, 4B, or 4C (shown in FIG. 1) is wide. Is likely to be distributed. In this case, the first living room supply amount adjustment step S635 is performed. On the other hand, when the minimum value W1s is larger than the fourth heating threshold value (for example, −3.0 ° C.), whether or not the value W1 of each room 4A, 4B, or 4C is distributed over a wide range only in this step S633. Therefore, the next step S634 is performed.

  In the first living room supply amount adjustment step S635, as shown in FIG. 10, the damper 20 (20a to 20c (shown in FIG. 1)) becomes larger as the living room 4A, 4B, or 4C (shown in FIG. 1) has a smaller value W1. ) Is set to be large (steps S660 to S666). For example, the smallest first opening degree is set for the dampers 20a, 20b, or 20c of the room 4A, 4B, or 4C in which the value W1 is greater than + 3.0 ° C. (step S661). The damper 20 of the room 4A, 4B, or 4C having the value W1 of + 3.0 ° C. to + 1.0 ° C. is set to a second opening larger than the first opening (step S662). The damper 20 of the living room 4A, 4B, or 4C having the value W1 of + 1.0 ° C. to −1.0 ° C. is set to a third opening that is larger than the second opening (step S663).

  Furthermore, the damper 20 (20a-20c) of the room 4A, 4B, or 4C in which the value W1 is −1.0 ° C. to −3.0 ° C. is set to a fourth opening that is larger than the third opening. (Step S664). The damper 20 of the room 4A, 4B, or 4C whose value W1 is less than −3.0 ° C. is set to a fifth opening that is larger than the fourth opening (step S665).

  And it is judged whether the opening degree of the damper 20 (20a-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S666). When it is determined that the openings of the dampers 20 in all the living rooms 4A, 4B, and 4C have been adjusted (“Y” in step S666), the series of processes in the first living room supply amount adjusting step S635 ends. On the other hand, when it is determined that the opening degree of the dampers 20 of all the living rooms 4A, 4B, and 4C is not adjusted (“N” in step S666), the dampers 20 of the other living rooms 4A, 4B, or 4C are selected. (Step S667), Steps S660 to S666 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A, 4B and 4C is adjusted based on the value W1, the supply amount of warm air (mixed air) to each of the living rooms 4A, 4B and 4C is Can be adjusted individually. Accordingly, each living room 4A, 4B, or 4C can be efficiently heated. In addition, about each threshold value which divided the opening degree of each damper 20 (20a-20c), it is not necessarily limited to said value, For example, according to the air volume of the fan 10B of the ventilation means 10, it can change suitably. .

  In step S634, as shown in FIG. 9, it is determined whether or not the maximum value W1m is greater than or equal to the fifth heating threshold value. If the maximum value W1m is significantly large, there is a high possibility that the values W1 of the respective rooms 4A, 4B or 4C are distributed over a wide range. 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 W1m is greater than or equal to the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S634), the value W1 of each living room 4A, 4B, or 4C may be widely distributed. Is expensive. In this case, the first living room supply amount adjustment step S635 shown in FIG. 10 is performed. On the other hand, when the maximum value W1m is less than the fifth heating threshold (for example, “+ 3.0 ° C.”) (“N” in step S634), the maximum value W1m is relatively small, and, based on the determination in step S633, The minimum value W1s is relatively large. Therefore, the possibility that the values W1 of the respective rooms 4A, 4B, or 4C are distributed over a wide range is low. In this case, the second living room supply amount adjustment step S636 is performed.

  In the second room supply amount adjustment step S636, as shown in FIG. 11, the dampers 20 (20a to 20c) of the room 4A, 4B, or 4C having the smaller value W1 as in the first room supply amount adjustment step S635. (Shown in FIG. 1) is set large (steps S670 to S675). For example, the smallest first opening degree is set for the damper 20 of the room 4A, 4B, or 4C in which the value W1 is greater than + 1.5 ° C. (step S671). The damper 20 of the living room 4A, 4B, or 4C having the value W1 of + 1.5 ° C. to + 0.5 ° C. is set to a second opening larger than the first opening (step S672). The damper 20 of the room 4A, 4B, or 4C having the value W1 of + 0.5 ° C. to −0.5 ° C. is set to a third opening that is larger than the second opening (step S673).

  Further, the damper 20 (20a to 20c) of the living room 4A, 4B, or 4C in which the value W1 is −0.5 ° C. to −1.5 ° C. is set to a fourth opening larger than the third opening. (Step S674). The damper 20 of the living room 4A, 4B, or 4C having the value W1 less than −1.5 ° C. is set to a fifth opening that is larger than the fourth opening (step S675).

  And it is judged whether the opening degree of the damper 20 (20a-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S676). When it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C have been adjusted (“Y” in step S676), the series of processes in the second room supply amount adjusting step S636 is completed. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C are not adjusted (“N” in step S676), the dampers 20 of the other living rooms 4A, 4B, or 4C are selected. (Step S677) and Steps S670 to S676 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A, 4B and 4C is adjusted based on the value W1, the supply amount of warm air (mixed air) to each of the living rooms 4A, 4B and 4C is Can be adjusted individually. Accordingly, each living room 4A, 4B, or 4C can be efficiently heated. In addition, about each threshold value which divided the opening degree of each damper 20 (20a-20c), it is not necessarily limited to said value.

  In the active operation step S622 of the present embodiment, as shown in FIG. 9, the set temperature of the air conditioner 16 is adjusted (air conditioning temperature adjustment steps S637 to S640).

  If it is determined in step S631 that the maximum value W1m is equal to or lower than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S631), the temperatures of all the living rooms 4A, 4B, or 4C are It has dropped significantly. And since maximum value W1m is below a 1st heating threshold value, minimum value W1s may be significantly smaller than a 1st heating threshold value. In this case, it is effective to heat the air conditioner 16 by increasing the set temperature. Accordingly, 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 S637). About 1st addition temperature, it can set suitably. The first addition temperature of the present embodiment is set to + 5 ° C., for example.

  In step S633, when it is determined that the minimum value W1s is equal to or lower than the fourth heating threshold (for example, −3.0 ° C.) (“Y” in step S633), the temperature of at least one of the living rooms 4A, 4B, and 4C. Is significantly lower than the target temperature. In this case, it is effective to heat the air conditioner 16 by increasing the set temperature. 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 S638).

  In step S634, when it is determined that the maximum value W1m is equal to or greater than the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S634), the temperature of at least one of the living rooms 4A, 4B, and 4C is The temperature is significantly higher than the target temperature. For this reason, it can be determined that it is not necessary to increase the set temperature of the air conditioner 16 in the air conditioning temperature adjustment steps S637 and S638. 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 S639). 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.

  When it is determined in step S634 that the maximum value W1m is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S634), as described above, the maximum value W1m is relatively small. And the minimum value W1s is relatively large. For this reason, the temperature of each room 4A, 4B, and 4C approximates the target temperature compared with other conditions. 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 S640).

  As described above, in the air conditioning temperature adjustment steps S637 to S640, the set temperature of the air conditioner 16 is increased as the minimum value W1s is decreased, and the set temperature of the air conditioner 16 is decreased as the maximum value W1m is increased. sell. Therefore, each living room 4A, 4B, or 4C can be effectively heated.

  Next, in the active operation step S622 of the present embodiment, the set air volume of the air conditioner 16 is adjusted (air conditioning air volume adjustment steps S641 to S644).

  In step S631, when it is determined that the maximum value W1m is equal to or less than the first heating threshold value (for example, −1.5 ° C.) (“Y” in step S631), the minimum value W1s is greater than the first heating threshold value. Since the air conditioner 16 may be significantly small, it is effective to heat the air conditioner 16 by increasing the set air volume. Accordingly, the set air volume of the air conditioner 16 is set to “strong” (air conditioning air volume adjustment step S641).

  Similarly, when it is determined in step S633 that the minimum value W1s is equal to or lower than the fourth heating threshold (for example, −3.0 ° C.) (“Y” in step S633), the set air volume of the air conditioner 16 is also the same. Is set to “strong” (air conditioning air volume adjustment step S642).

  If it is determined in step S634 that the maximum value W1m is equal to or greater than the fifth heating threshold value (for example, + 3.0 ° C.) (“Y” in step S634), the air conditioner is adjusted in steps S641 and S642. It can be determined that there is no need to increase the set air volume of 16. For this reason, the set air volume of the air conditioner 16 is set to “weak” (air conditioning air volume adjustment step S643).

  In step S634, when it is determined that the maximum value W1m is less than the fifth heating threshold value (for example, + 3.0 ° C.) (“N” in step S634), the air conditioner air adjustment steps S641 and S642 are performed. Although it is not necessary to increase the set air volume of 16, it is effective to increase the set air volume of the air conditioner 16 rather than the air conditioning air volume adjusting step S643. For this reason, the set air volume of the air conditioner 16 is set to “medium” (air conditioning air volume adjusting step S644).

  In this way, in the air conditioning air volume adjustment steps S641 to S644, the smaller the minimum value W1s, the larger the set air volume of the air conditioner 16, and the larger the maximum value W1m, the smaller the air volume set air volume 16 is. sell. Therefore, each living room 4A, 4B, or 4C can be effectively heated.

  Next, in the active operation step S622 of the present embodiment, the air volume of the fan 10B of the ventilation means 10 is adjusted (fan air volume adjustment steps S645 to S648).

In step S631, when it is determined that the maximum value W1m is equal to or less than the first heating threshold (for example, −1.5 ° C.) (“Y” in step S631), from the same viewpoint as the air conditioning air volume adjustment step S641, The air volume of the fan 10B is set to a fourth air volume (for example, 1000 m ³ / h) (fan air volume adjustment step S645). In Step S633, when it is determined that the minimum value W1s is equal to or less than the fourth heating threshold value (for example, −3.0 ° C.) (“Y” in Step S633), the same viewpoint as in the air conditioning air volume adjustment step S642 Thus, the air volume of the fan 10B is set to the fourth air volume (for example, 1000 m ³ / h) (fan air volume adjustment step S646).

In step S634, when the maximum value W1m is equal to or greater than the fifth heating threshold (for example, + 3.0 ° C.) (“Y” in step S634), the air volume of the fan 10B is determined from the same viewpoint as the air conditioning air volume adjustment step S643. The second air volume (for example, 600 m ³ / h) is set (fan air volume adjusting step S647). Further, in step S634, when the maximum value W1m is less than the fifth heating threshold (for example, + 3.0 ° C.) (“N” in step S634), from the same viewpoint as the air conditioning air volume adjustment step S644, The air volume is set to a third air volume (for example, 800 m ³ / h) (fan air volume adjustment step S648).

  As described above, in the fan air volume adjustment steps S645 to S648, the air volume of the fan 10B can be increased as the minimum value W1s is decreased, and the air volume of the fan 10B can be decreased as the maximum value W1m is increased. Therefore, each living room 4A, 4B, or 4C can be effectively heated. After the process of the fan air volume adjustment steps S645 to S648 is completed, a series of processes of the active operation step S622 and the heating step S235 (shown in FIG. 8) is completed.

FIG. 12 is a flowchart illustrating an example of a processing procedure of the efficient operation step S623 of the present embodiment. As described above, in the efficient operation step S623, the air conditioner 16 is efficiently operated. In the efficiency operation step S623, first, 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 (1).
Ew = (Tb−Ta) × Af × Hs / 1000 (1)
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 portion 16a is measured by the intake temperature detection means 27. 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. 13A is a graph showing the relationship between the heating capacity and COP (Coefficient of Performance). In the graph of FIG. 13A, COP, power consumption (kW), and sensible heat load (kW) are shown. 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 S623, as shown in FIG. 12, 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 heating efficiency is bad, the efficient driving | operation of the air conditioner 16 after step S683 is performed.

  When it is determined that the current heating efficiency of the air conditioner 16 is poor (“Y” in step S682), the next step S683 is performed prior to the efficient operation of the air conditioner 16. On the other hand, when it is determined that the current heating efficiency of the air conditioner 16 is not bad (“N” in step S682), the air conditioner 16 has already been efficiently operated. For this reason, a series of the efficiency operation step S623 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.

  Next, in the efficiency operation step S623, it is determined whether or not the set temperature of the air conditioner 16 is higher than a target temperature (for example, 20 ° C.) (step S683). When the set temperature of the air conditioner 16 is higher than the target temperature (“Y” in step S683), each room 4A, 4B, or 4C can be heated to the target temperature even if the set temperature is slightly reduced. In such a case, the set temperature of the air conditioner 16 is decreased (step S685) while maintaining the openings of the dampers 20a to 20c (step S684). 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 ° C., for example.

Further, the set air volume of the air conditioner 16 is set to “medium” (step S686), and the air volume of the fan 10B is set to the third air volume (for example, 800 m ³ / h) (step S687). Thereby, in efficient operation step S623, each living room 4A, 4B, or 4C can be heated efficiently.

  When the set temperature of the air conditioner 16 is equal to or lower than the target temperature (“N” in step S683), if the set temperature is further reduced, each room 4A, 4B, or 4C may not be maintained at the target temperature. . For this reason, the opening degree of the dampers 20a to 20c is maintained (step S688), and the set temperature of the air conditioner 16 is maintained (step S689).

Further, the set air volume of the air conditioner 16 is set to “weak” (step S690), and the air volume of the fan 10B is set to the second air volume (for example, 600 m ³ / h) (step S691). Thereby, in efficient operation step S623, each living room 4A, 4B, or 4C can be heated efficiently, preventing the deterioration of the heating efficiency of the air conditioner 16.

  Next, in the efficiency operation step S623, the operation of the air conditioner 16 and the fan 10B is performed in a state where the set temperature, the set air volume, and the air volume of the fan 10B set in steps S684 to S691 are maintained. Is left behind (step S692). Thereby, each living room 4A, 4B, or 4C can be efficiently heated, preventing the deterioration of the heating efficiency of the air conditioner 16. The remaining time can be set as appropriate. In this embodiment, considering that each living room 4A, 4B, or 4C is efficiently heated by the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B set in the efficiency operation step S623, 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 S623 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 or 4C is effectively heated by the set temperature of the air conditioner 16 set in the heating mode S23, the set air volume, and the air volume of the fan 10B, For example, it is desirable to set for about 30 minutes.

  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, the opening degree of the damper 20, the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B are based on the temperature of each living room 4A, 4B, or 4C that changes every moment. Each room 4A, 4B or 4C can be effectively heated because it is adjusted. In addition, although the difference V1 of this embodiment illustrated the aspect calculated | required as value W1 which deducted target temperature from the temperature of each living room 4A, 4B, and 4C, it is not limited to this. For example, you may obtain | require as a value which deducted the temperature of each room 4A, 4B, and 4C from target temperature.

  Next, in the passive heating mode S24, the underfloor air 17 is supplied to the living rooms 4A, 4B, and 4C, whereby the living rooms 4A, 4B, and 4C are air-conditioned while being ventilated. FIG. 14 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, 4B, and 4C are detected (step S241). The temperature of each room 4A, 4B and 4C is detected by the room temperature detection means 25, respectively. The temperature of each room 4A, 4B, and 4C 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, 4B, and 4C 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, 4B, and 4C is higher than the temperature (for example, 15 ° C.) at which the heating operation by the air conditioner 16 is required (“Y” in step S244), the underfloor air 17 is used. Therefore, it can be determined that heating (air conditioning) is possible. In such a case, the next step S245 is performed. On the other hand, when the temperature of each room 4A, 4B, and 4C is below the temperature (for example, 15 degreeC) in which the heating operation by the air conditioner 16 is required (in step S244. "N"), the underfloor air 17 is changed. Even if it uses, it can be judged that each room 4A, 4B, and 4C cannot fully be 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, 4B, and 4C due to the outside air is small. 17 can be used to determine that each room 4A, 4B, and 4C 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), even if the underfloor air 17 is used, each of the rooms 4A, 4B, and 4C is sufficient. It can be determined that heating 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), each of the living rooms 4A and 4B is used by using the underfloor air 17 having a relatively high temperature. 4C can be heated (air-conditioned). 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 living rooms 4A, 4B, and 4C are used even when the underfloor air 17 is used. Can not be effectively 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, the underfloor air 17 is supplied to the living rooms 4A, 4B, and 4C (first supply step S247). In the first supply step S247, the temperature of each of the rooms 4A, 4B, and 4C 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 based on the determination in steps S244 to S246. 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 and is equal to or higher than a predetermined temperature. Accordingly, in the first supply step S247, the temperatures of the living rooms 4A, 4B, and 4C, the temperature of the outside air, and the temperature of the underfloor air 17 are relatively high, so that the underfloor air 17 can be used without using the air conditioner 16. Each room 4A, 4B and 4C can be effectively heated (air-conditioned) using Therefore, an increase in air conditioning cost can be prevented. FIG. 15 is a flowchart illustrating an example of the processing procedure of the first supply step S247.

As shown in FIGS. 1, 2 and 15, in the first supply step S247 of the present embodiment, first, the air volume of the fan 10B of the ventilation means 10 (total supply volume of the underfloor air 17) is set (step). S711). The air volume of the fan 10B according to the present embodiment is set to a relatively small second air volume (600 m ³ / h), for example, in consideration of 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 purification device 10C, and then each room 4A via the damper 20 (20a to 20c). It can be supplied to the space 4 on the floor such as 4B and 4C.

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

  Difference Va is calculated | required for every room 4A, 4B, and 4C. Difference Va of this embodiment is calculated | required as a value which deducted target temperature from the temperature of each room 4A, 4B, and 4C similarly to heating mode S23. The larger this value (difference Va), the higher the temperature of each of the rooms 4A, 4B, and 4C.

  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, 4B, and 4C cannot be heated to the target temperature. However, each of the living rooms 4A, 4B, and 4C according to the present embodiment has internal heat generated by home appliances, residents, and the like. Therefore, even if the underfloor air 17 that is slightly lower than the target temperature is used, each of the living rooms 4A, 4B. And 4C can be sufficiently warmed to the target 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-20c) of each room 4A, 4B, and 4C is adjusted based on the said difference Va of each room 4A, 4B, and 4C (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, or 4C where the difference Va is smaller. Thereby, since the warmer underfloor air 17 is supplied to the living rooms 4A, 4B, and 4C having lower temperatures, the living rooms 4A, 4B, and 4C can be efficiently heated.

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

  Further, the damper 20 (20a to 20c) of the living room 4A, 4B, or 4C in which the difference Va is −0.5 ° C. to −1.5 ° C. is set to a fourth opening larger than the third opening. (Step S717). The damper 20 of the living room 4A, 4B, or 4C 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-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S719). When it is determined that the openings of the dampers 20 of all the rooms 4A, 4B, and 4C have been adjusted (“Y” in step S719), the next step S248 (shown in FIG. 14) is performed. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C are not adjusted (“N” in step S719), the dampers 20 of the other living rooms 4A, 4B, or 4C 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, 4B, and 4C can be adjusted based on the difference Va. Accordingly, the supply amount of the underfloor air 17 to the living rooms 4A, 4B, and 4C can be individually adjusted.

  In addition, each threshold value (in this embodiment, “+ 1.5 ° C.”, “+ 0.5 ° C.”, “−0.5 ° C.”) of the difference Va obtained by dividing each opening degree of the damper 20 (20a-20c), About "-1.5 degreeC"), for example, according to the air volume of the fan 10B of the ventilation means 10, it can change suitably. 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, 4B, and 4C was illustrated, it is not limited to this. For example, you may obtain | require as a value which deducted the temperature of each room 4A, 4B, and 4C from 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 FIG. 1 and FIG. 14, in the passive heating mode S24, the underfloor air 17 to the living rooms 4A, 4B, and 4C 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 20c) of the living rooms 4A, 4B and 4C set in the first supply step S247, 4A, 4B and 4C 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 of the ventilation means 10, the supply amount of the underfloor air 17 to the living rooms 4A, 4B, and 4C, etc., for example, it is set to about 20 to 30 minutes.

  Next, in the passive heating mode S24, it is determined whether or not the temperature of each of the rooms 4A, 4B, and 4C is equal to or higher than a predetermined temperature (step S249). About "predetermined temperature" of each living room 4A, 4B, and 4C, 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 rooms 4A, 4B, and 4C is increasing toward the target temperature using the underfloor air 17.

  When the temperature of each room 4A, 4B, and 4C is equal to or higher than the temperature (19 ° C.) (“Y” in step S249), each room 4A, 4B, and 4C is effectively heated using the underfloor air 17. It can be determined that In such a case, the next step S250 is performed. On the other hand, when the temperature of each of the rooms 4A, 4B, and 4C is lower than the temperature (that is, the temperature of at least one of the rooms 4A, 4B, and 4C is lower than the temperature) (“N” in step S249), the underfloor air 17 Even if it uses, it can be judged that each living room 4A, 4B and 4C cannot be heated effectively. 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 when the underfloor air 17 is supplied to each of the rooms 4A, 4B, and 4C for a certain period of time, when it is determined that the rooms 4A, 4B, and 4C are not sufficiently heated, the passive heating mode is set. S24 is interrupted and heating mode S23 is implemented rapidly. Accordingly, the living rooms 4A, 4B, and 4C 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). When it is determined that the current period is the first period (“Y” in step S250), steps S245 to S250 are performed again. Thereby, in the 1st period (winter passive period), even if it does not use the air conditioner 16, each living room 4A, 4B, and 4C can be continuously heated (air-conditioned) using only natural energy. Increase in air conditioning 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.

  When the series of processes of the ventilation mode S22, the heating mode S23, and the passive heating mode S24 described above are completed, the next step S4 (shown in FIG. 4) is performed. Thereby, in winter air-conditioning step S2, each living room 4A, 4B, and 4C can be efficiently heated (air-conditioned) according to the period to which the present belongs.

  FIG. 16 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 16, in the summer air conditioning step S3, an intermediate period in which cooling by the air conditioner 16 is unnecessary, a cooling period in which cooling by the air conditioner is required, and between the intermediate period and the cooling period In the second period (hereinafter, simply referred to as “summer passive period”), different processing procedures are performed. The intermediate periods are, for example, April 28 to June 16 and September 23 to October 25. The cooling period is, for example, from August 1 to August 21. The second period (summer passive period) is, for example, June 17 to July 31, and August 22 to September 22. 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.

  In the summer air conditioning step S3, it is first determined whether the present time belongs to an intermediate period, a cooling period, or a second period (summer passive period) (step S31). These determinations are made by the control means 26. 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. Further, the fan 10B of the ventilation means 10 is operated. Thereby, the underfloor air 17 is supplied to each living room 4A, 4B, and 4C via the chamber box 9, the ventilation means 10, and the damper 20 (20a-20c). In addition, the air in the living rooms 4A, 4B, and 4C is discharged to the outdoors by an exhaust fan 38 and the like. Thereby, each living room 4A, 4B, and 4C is ventilated by the clean external air. A series of processing in these ventilation modes S32 is performed by the control means 26. The air volume of the fan 10B is set to the first air volume (for example, 175 m ³ / h). The damper 20 of each living room 4A, 4B or 4C 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 each of the living rooms 4A, 4B, and 4C. FIG. 17 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, 4B, and 4C 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 this embodiment may be set for each of the rooms 4A, 4B, and 4C, 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, 4B, and 4C are detected (step S331). The temperature of each room 4A, 4B and 4C is detected by the room temperature detection means 25 (25a-25c), respectively. The temperature of each room 4A, 4B, and 4C is transmitted to the control means 26.

  Next, in the cooling mode S33, a difference V2 between the temperature of each of the rooms 4A, 4B and 4C and a predetermined target temperature is obtained (step S332). The difference V2 is obtained for each of the living rooms 4A, 4B, and 4C. The difference V2 in the present embodiment is obtained as a value W2 obtained by subtracting the target temperature from the temperatures of the living rooms 4A, 4B, and 4C. The smaller this value W2 (difference V2), the lower the temperature of each living room 4A, 4B and 4C.

  Next, in the cooling mode S33, it is determined whether or not the value W2 of all the rooms 4A, 4B, and 4C is equal to or less than a predetermined second cooling threshold (step S333). In step S233, 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.

  When it is determined that the values W1 of all the living rooms 4A, 4B, and 4C are equal to or lower than a predetermined second cooling threshold (for example, −1.5 ° C.) (“Y” in step S333), all The temperatures of the living rooms 4A, 4B and 4C are lower than the target temperature (for example, 28 ° C.) and are 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 W1 of all the living rooms 4A, 4B, and 4C is larger than a predetermined second cooling threshold (for example, −1.5 ° C.) (“N” in step S333). Since all the living rooms 4A, 4B and 4C are 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, 4B, and 4C is executed.

  FIG. 18 is a flowchart illustrating an example of a processing procedure of the cooling step S335. In the cooling step S335, first, cooling by the air conditioner 16 is started (step S820). In step S820 of the present embodiment, first, similarly to the heating mode S23, the first space 9A and the second space 9B are communicated, and the air conditioner 16 is cooled. Further, the fan 10B of the ventilation means 10 is 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 the living rooms 4A, 4B and 4C by the ventilation means 10. Thereby, cooling (air conditioning) by the air conditioner 16 can be realized while performing ventilation. The set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B can be set as appropriate. Note that if the air conditioner 16 has already started cooling, step S820 is omitted.

  Next, in the cooling step S335, it is first determined whether or not the largest maximum value W2m among the values W2 of the respective rooms 4A, 4B, or 4C is equal to or greater than a predetermined third cooling threshold. (Step S821). In step S821, it is determined whether or not 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 W2m is equal to or greater than the third cooling threshold (for example, + 0.5 ° C.) (“Y” in step S821), the temperature of the room 4A, 4B, or 4C is high. For this reason, the active operation step S822 for performing the active operation of the air conditioner 16 is performed. On the other hand, when the maximum value W2m is smaller than the third cooling threshold (for example, + 0.5 ° C.) (“N” in step S821), the respective rooms 4A, 4B, and 4C are relatively cooled. For this reason, the efficient operation step S823 in which the efficient operation of the air conditioner 16 is performed is performed.

  FIG. 19 is a flowchart illustrating an example of a processing procedure of the active operation step S822 of the present embodiment. In the active operation step S822, it is first determined whether or not the smallest minimum value W2s among the values W2 of the respective rooms 4A, 4B, or 4C is equal to or greater than a predetermined first cooling threshold (step S831). In this step S831, it is determined whether or not it is necessary to cool by maximizing the amount of cold air (mixed air) supplied to each room 4A, 4B or 4C. Therefore, the first cooling threshold is preferably set to a value larger than the third cooling threshold (for example, + 0.5 ° C.) used in the previous step. The first cooling threshold in this embodiment is set to + 1.5 ° C.

  When the minimum value W2s is equal to or higher than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S831), the temperature of all the rooms 4A, 4B, or 4C is significantly increased. For this reason, the supply amount of cold air (mixed air) to each living room 4A, 4B, or 4C is set to the maximum (step S832). In step S832, the damper 20 of each room 4A, 4B, or 4C is set to the largest fifth opening. Thereby, the supply amount of the cold air to each living room 4A, 4B or 4C can be maximized.

  On the other hand, when the minimum value W2s is less than the first cooling threshold value (for example, “+ 1.5 ° C.”) (“N” in step S831), the temperatures of all the living rooms 4A, 4B, or 4C are significantly increased. Do not mean. Therefore, it is effective to efficiently cool each living room 4A, 4B or 4C by individually adjusting the amount of cold air (mixed air) supplied to each living room 4A, 4B or 4C. In this case, after the next step S833 and step S834 are executed, a room supply amount adjustment step for individually adjusting the amount of cold air supplied to each room 4A, 4B, or 4C is performed. The room supply amount adjustment step of the present embodiment includes a first room supply amount adjustment step S835 and a second room supply amount adjustment step S836.

  FIG. 20 is a flowchart illustrating an example of the processing procedure of the first living room supply amount adjustment step S835. FIG. 21 is a flowchart showing an example of the processing procedure of the second room supply amount adjustment step S836. In the first living room supply amount adjustment step S835 and the second living room supply amount adjustment step S836, the dampers 20 (20a to 20c) of the living rooms 4A, 4B, and 4C are based on the value W2 of the living rooms 4A, 4B, and 4C. The opening is adjusted. In this embodiment, the opening degree of the damper 20 is set to be larger for the living rooms 4A, 4B, and 4C where the value W2 is larger. Thereby, since more cold air (mixed air) is supplied to the living rooms 4A, 4B, and 4C having higher temperatures, each of the living rooms 4A, 4B, and 4C can be efficiently cooled.

  For each of the first opening to the fifth opening of each of the dampers 20a to 20c, a threshold range of the value W2 of each living room 4A, 4B, or 4C is set. Similar to the heating mode S23, the first room supply amount adjustment step S835 has a larger threshold range than the second room supply amount adjustment step S836. Therefore, in the first room supply amount adjustment step S835, even if the value W2 of each room 4A, 4B or 4C is distributed over a wide range, the opening degree of each damper 20a to 20c for each room 4A, 4B or 4C. Can be adjusted in a well-balanced manner. The details of the first living room supply amount adjustment step S835 and the second living room supply amount adjustment step S836 will be described later.

  As shown in FIG. 19, in step S833, it is determined whether or not the largest maximum value W2m among the values W2 of the respective rooms 4A, 4B, or 4C is equal to or greater than the fourth cooling threshold. If the maximum value W2m is significantly large, there is a high possibility that the values W2 of the respective rooms 4A, 4B, or 4C 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 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 W2m is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S833), the value W2 of each living room 4A, 4B, or 4C may be widely distributed. Is expensive. In this case, the first living room supply amount adjustment step S835 is performed. On the other hand, when the maximum value W2m is less than the fourth cooling threshold (for example, + 3.0 ° C.), only in this step S833, whether or not the value W1 of each living room 4A, 4B, or 4C is distributed over a wide range. Since it cannot be determined, the next step S834 is performed.

  In the first room supply amount adjustment step S835, as shown in FIG. 20, the opening degree of the damper 20 (20a to 20c (shown in FIG. 1)) is larger in the room 4A, 4B, or 4C where the value W2 is larger. It has been set (steps S860 to S865). For example, the smallest first opening degree is set for the damper 20 of the living room 4A, 4B, or 4C in which the value W2 is less than −3.0 ° C. (step S861). The damper 20 of the room 4A, 4B, or 4C having the value W2 of −3.0 ° C. to −1.0 ° C. is set to a second opening that is larger than the first opening (step S862). The damper 20 of the living room 4A, 4B, or 4C having the value W2 of −1.0 to +1.0 is set to a third opening that is larger than the second opening (step S863).

  Furthermore, the damper 20 (20a-20c) of the room 4A, 4B, or 4C in which the value W2 is +1.0 to +3.0 is set to a fourth opening larger than the third opening (step S864). . The damper 20 of the room 4A, 4B, or 4C having the value W2 larger than +3.0 is set to the fifth opening that is larger than the fourth opening (step S865).

  And it is judged whether the opening degree of the damper 20 (20a-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S866). When it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C have been adjusted (“Y” in step S866), the series of processes in the first room supply amount adjusting step S835 is completed. On the other hand, when it is determined that the opening degree of the dampers 20 of all the living rooms 4A, 4B, and 4C is not adjusted (“N” in step S866), the dampers 20 of the other living rooms 4A, 4B, or 4C are selected. (Step S867) and Steps S861 to S866 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A, 4B and 4C is adjusted based on the value W2, the amount of cold air (mixed air) supplied to each of the living rooms 4A, 4B and 4C is Can be adjusted individually. Therefore, each living room 4A, 4B or 4C can be efficiently cooled. In addition, about each threshold value which divided the opening degree of each damper 20 (20a-20c), it is not necessarily limited to said value.

  Next, in step S834, as shown in FIG. 19, it is determined whether or not the minimum value W2s is equal to or less than the fifth cooling threshold value. When the minimum value W2s is significantly small, there is a high possibility that the values W2 of the respective rooms 4A, 4B, or 4C are distributed over a wide range. 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 W2s is equal to or lower than the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S834), the values W2 of the respective rooms 4A, 4B, or 4C may be distributed over a wide range. High nature. In this case, the first living room supply amount adjustment step S835 shown in FIG. 20 is performed. On the other hand, when the minimum value W2s is larger than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S834), the minimum value W2s is relatively large, and moreover, from the determination in step S833. The maximum value W2m is relatively small. Therefore, it is unlikely that the value W2 of each living room 4A, 4B or 4C is distributed over a wide range. In this case, the second living room supply amount adjustment step S836 is performed.

  In the second room supply amount adjustment step S836, as shown in FIG. 21, the damper 20 (20a to 20c (20a to 20c ( 1)) is set to be large (steps S870 to S875). For example, the smallest first opening degree is set for the damper 20 of the living room 4A, 4B, or 4C in which the value W2 is less than −1.5 ° C. (step S871). The damper 20 of the living room 4A, 4B, or 4C having the value W2 of −1.5 ° C. to −0.5 ° C. is set to a second opening larger than the first opening (step S872). The damper 20 of the living room 4A, 4B, or 4C having the value W2 of −0.5 to +0.5 is set to a third opening that is larger than the second opening (step S873).

  Furthermore, the damper 20 (20a-20c) of the living room 4A, 4B, or 4C having the value W2 of +0.5 to +1.5 is set to a fourth opening that is larger than the third opening (step S874). . The damper 20 of the room 4A, 4B, or 4C having the value W2 larger than +1.5 is set to the fifth opening that is larger than the fourth opening (step S875).

  And it is judged whether the opening degree of the damper 20 (20a-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S876). When it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C have been adjusted (“Y” in step S876), the series of processes in the second room supply amount adjusting step S836 is completed. On the other hand, when it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C are not adjusted (“N” in step S876), the dampers 20 of the other living rooms 4A, 4B, or 4C are selected. (Step S877), Steps S870 to S876 are performed again. Thereby, since the opening degree of the damper 20 of all the living rooms 4A, 4B and 4C is adjusted based on the value W2, the amount of cold air (mixed air) supplied to each of the living rooms 4A, 4B and 4C is Can be adjusted individually. Therefore, each living room 4A, 4B or 4C can be efficiently cooled. In addition, about each threshold value which divided the opening degree of each damper 20 (20a-20c), it is not necessarily limited to said value.

  In the active operation step S822 of this embodiment, as shown in FIG. 19, the set temperature of the air conditioner 16 is adjusted (air conditioning temperature adjustment steps S837 to S840).

  If it is determined in step S831 that the minimum value W2s is equal to or higher than the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S831), the temperatures of all the living rooms 4A, 4B, or 4C are greatly increased. Is rising. Moreover, since the minimum value W2s is greater than or equal to the first cooling threshold, the maximum value W2m may be significantly larger than the first cooling threshold. In this case, it is effective to cool the air conditioner 16 by lowering the set temperature. Accordingly, 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 S837). About 1st subtraction temperature, it can set suitably. The 1st subtraction temperature of this embodiment is set as -5 ° C, for example.

  In step S833, when it is determined that the maximum value W2m is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S833), the temperature of at least one of the living rooms 4A, 4B, and 4C is the target It is much larger than the temperature. 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 (for example, −5 ° C.) (air conditioning temperature adjustment step S838).

  If it is determined in step S834 that the minimum value W2s is equal to or lower than the fifth cooling threshold (eg, −3.0 ° C.) (“Y” in step S834), the temperature of at least one of the living rooms 4A, 4B, and 4C Is significantly lower than the target temperature. For this reason, it can be determined that it is not necessary to increase the set temperature of the air conditioner 16 in the air conditioning temperature adjustment steps S837 and S838. 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 S839). 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.

  If it is determined in step S834 that the minimum value W2s is greater than the fifth cooling threshold (eg, −3.0 ° C.) (“N” in step S834), as described above, the minimum value W2s is relatively It is large and the maximum value W2m is relatively small. For this reason, the temperature of each room 4A, 4B, and 4C approximates the target temperature compared with other conditions. Accordingly, the set temperature of the air conditioner 16 is set to the difference between the target temperature and the second subtracted temperature (for example, −2 ° C.) (air conditioning temperature adjustment step S840).

  As described above, in the air conditioning temperature adjustment steps S837 to S840, the set temperature of the air conditioner 16 is decreased as the maximum value W2m is increased, and the set temperature of the air conditioner 16 is increased as the minimum value W2s is decreased. sell. Therefore, each room 4A, 4B or 4C can be effectively cooled.

  Next, in the active operation step S822 of the present embodiment, the set air volume of the air conditioner 16 is adjusted (air conditioning air volume adjustment steps S841 to S844).

  If it is determined in step S831 that the minimum value W2s is greater than or equal to the first cooling threshold (for example, + 1.5 ° C.) (“Y” in step S831), the maximum value W2m is significantly greater than the first cooling threshold. Therefore, it is effective to increase the set air volume of the air conditioner 16 for cooling. Accordingly, the set air volume of the air conditioner 16 is set to “strong” (air conditioning air volume adjustment step S841).

  Similarly, when it is determined in step S833 that the maximum value W2m is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S833), the set air volume of the air conditioner 16 is also the same. , “Strong” is set (air conditioning air volume adjustment step S842).

  If it is determined in step S834 that the minimum value W2s is equal to or less than the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S834), the air conditioning air conditioning steps S841 and S842 are performed in the air conditioning. It can be determined that there is no need to increase the set air volume of the machine 16. For this reason, the set air volume of the air conditioner 16 is set to “weak” (air conditioning air volume adjustment step S843).

  If it is determined in step S834 that the minimum value W2s is greater than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S834), the air conditioning air conditioning steps S841 and S842 are performed as air conditioning. Although it is not necessary to increase the set air volume of the machine 16, it is effective to increase the set air volume of the air conditioner 16 rather than the air conditioning air volume adjustment step S843. For this reason, the set air volume of the air conditioner 16 is set to “medium” (air conditioning air volume adjusting step S844).

  As described above, in the air conditioning air volume adjustment steps S841 to S844, the larger the maximum value W2m, the larger the set air volume of the air conditioner 16, and the smaller the minimum value W2s, the smaller the set air volume of the air conditioner 16 can be. . Therefore, each room 4A, 4B or 4C can be effectively cooled.

  Next, in the active operation step S822 of this embodiment, the air volume of the fan 10B of the ventilation means 10 is adjusted (fan air volume adjustment steps S845 to S848).

If it is determined in step S831 that the minimum value W2s is equal to or greater than the first cooling threshold value (for example, + 1.5 ° C.) (“Y” in step S831), the fan is determined from the same viewpoint as in the air conditioning air volume adjustment step S841. The air volume of 10B is set to the fourth air volume (for example, 1000 m ³ / h) (fan air volume adjustment step S845). If it is determined in step S833 that the maximum value W2m is equal to or greater than the fourth cooling threshold (for example, + 3.0 ° C.) (“Y” in step S833), from the same viewpoint as in the air conditioning air volume adjustment step S842. The air volume of the fan 10B is set to the fourth air volume (for example, 1000 m ³ / h) (fan air volume adjustment step S846).

In step S834, when it is determined that the minimum value W2s is equal to or less than the fifth cooling threshold (for example, −3.0 ° C.) (“Y” in step S834), from the same viewpoint as the air conditioning air volume adjustment step S843, The air volume of the fan 10B is set to the second air volume (for example, 600 m ³ / h) (fan air volume adjustment step S847). If it is determined in step S834 that the minimum value W2s is greater than the fifth cooling threshold (for example, −3.0 ° C.) (“N” in step S834), the same viewpoint as in the air conditioning air volume adjustment step S844 Thus, the air volume of the fan 10B is set to the third air volume (for example, 800 m ³ / h) (fan air volume adjustment step S848).

  Thus, in the fan air volume adjustment steps S845 to S848, the air volume of the fan 10B can be increased as the maximum value W2m is increased, and the air volume of the fan 10B can be decreased as the minimum value W2s is decreased. Therefore, each room 4A, 4B or 4C can be effectively cooled. After the processing of the fan air volume adjustment steps S845 to S848 is completed, a series of processing of the active operation step S822 and the cooling step S335 (shown in FIG. 18) is completed.

FIG. 22 is a flowchart illustrating an example of a processing procedure of the efficient operation step S823 of the present embodiment. As described above, in the efficient operation step S823, efficient operation of the air conditioner 16 is performed. In the efficiency operation step S823, first, the current cooling capacity of the air conditioner 16 is calculated (step S881). In the cooling mode S33 of the present embodiment, the cooling capacity Ec of the air conditioner 16 is obtained by the following formula (2).
Ec = (Ta−Tb) × Af × Hs / 1000 (2)
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. 13B is a graph showing the relationship between the cooling capacity and COP (Coefficient of Performance). In the graph of FIG. 13B, COP, power consumption (kW), sensible heat load (kW), and latent heat load (kW) are shown. 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. 22, in the efficiency operation step S823, it is determined whether or not the current cooling efficiency of the air conditioner 16 is poor (step S882). 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 cooling efficiency of the air conditioner 16 is poor (“Y” in step S882), the next step S883 is performed prior to the efficient operation of the air conditioner 16. On the other hand, when it is determined that the current cooling efficiency of the air conditioner 16 is not bad (“N” in step S882), the air conditioner 16 has already been efficiently operated. For this reason, a series of the efficiency operation step S823 and the cooling step S335 (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. The process ends.

  Next, in the efficiency operation step S823, it is determined whether or not the set temperature of the air conditioner 16 is lower than a target temperature (for example, 20 ° C.) (step S883). When the set temperature of the air conditioner 16 is lower than the target temperature (“Y” in step S883), each room 4A, 4B, or 4C can be cooled to the target temperature even if the set temperature is slightly increased. . In such a case, the set temperature of the air conditioner 16 is set to a large value (step S885) while the openings of the dampers 20a to 20c are maintained (step S884). 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 “medium” (step S886), and the air volume of the fan 10B is set to the third air volume (for example, 800 m ³ / h) (step S887). Thereby, in efficient operation step S823, each living room 4A, 4B, or 4C can be cooled efficiently.

  When the set temperature of the air conditioner 16 is equal to or higher than the target temperature (“N” in step S883), if the set temperature is further increased, each room 4A, 4B, or 4C cannot be maintained at the target temperature. There is a fear. For this reason, while the opening degree of the dampers 20a to 20c is maintained (step S888), the set temperature of the air conditioner 16 is maintained (step S889).

Further, the set air volume of the air conditioner 16 is set to “weak” (step S890), and the air volume of the fan 10B is set to the second air volume (for example, 600 m ³ / h) (step S891). Thereby, in efficiency operation step S823, each living room 4A, 4B, or 4C can be efficiently cooled, preventing the deterioration of the cooling efficiency of the air conditioner 16.

  Next, in the efficiency operation step S823, the air conditioner 16 and the fan 10B of 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 the steps S884 to S891 are maintained. Operation is left behind (step S892). Thereby, each living room 4A, 4B or 4C can be efficiently cooled while preventing deterioration of the cooling efficiency of the air conditioner 16. The remaining time can be set as appropriate. In the present embodiment, considering that each room 4A, 4B, or 4C is 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 efficiency operation step S823, For example, it is desirable to set it to about 5 minutes. After the process of step S892, the series of processes of the efficiency operation step S623 and the cooling step S335 (shown in FIG. 18) is completed.

  Next, as shown in FIG. 17, 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 each living room 4A, 4B, or 4C is effectively cooled by the set temperature, the set air volume, and the air volume of the fan 10B set in the cooling mode S33, 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 the cooling mode S33, the opening degree of the damper 20, the set temperature of the air conditioner 16, the set air volume, and the air volume of the fan 10B are based on the temperature of each living room 4A, 4B or 4C that changes every moment. Each room 4A, 4B or 4C can be effectively cooled because it is adjusted. In addition, although the aspect calculated | required as value W2 which subtracted target temperature from the temperature of each living room 4A, 4B, and 4C was illustrated as the difference V2 of this embodiment, it is not limited to this. For example, you may obtain | require as a value which deducted the temperature of each room 4A, 4B, and 4C from target temperature.

  In the passive cooling mode S34, the underfloor air 17 is supplied to the living rooms 4A, 4B, and 4C, whereby the living rooms 4A, 4B, and 4C are air-conditioned while being ventilated. FIG. 23 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, 4B, and 4C 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, 4B and 4C, 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 rooms 4A, 4B, and 4C 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, 4B, and 4C is lower than the temperature (for example, 31 ° C.) that requires cooling operation by the air conditioner 16 (“Y” in step S344), the underfloor air 17 is used. Therefore, it can be determined that cooling (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, 4B, and 4C is equal to or higher than the temperature (for example, 31 ° C.) at which the cooling operation by the air conditioner 16 is required (“N” in step S344), the underfloor air 17 is Even if it uses, it can be judged that each room 4A, 4B, and 4C cannot be cooled effectively. In such a case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 16 and 17) 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), the influence of the temperature rise of the living rooms 4A, 4B, and 4C due to the outside air is small. It can be determined that each of the living rooms 4A, 4B, and 4C can be cooled (air-conditioned) by using. 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), even if the underfloor air 17 is used, the respective rooms 4A, 4B, and 4C are effective. 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. 16 and 17) 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 and 4B is utilized using the underfloor air 17 having a relatively low temperature. And 4C can be determined to 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), each of the living rooms 4A, 4B, and 4C is used 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. 16 and 17) is performed.

  Next, in the passive cooling mode S34, the underfloor air 17 is supplied to the living rooms 4A, 4B, and 4C (second supply step S347). In the second supply step S347, the temperature of each of the rooms 4A, 4B, and 4C 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 based on the determination in steps S344 to S346. This is performed only when it is determined that the temperature of the underfloor air 17 is lower than a predetermined temperature and that the temperature of the underfloor air 17 is lower than the predetermined temperature. Therefore, in the second supply step S347, the temperatures of the living rooms 4A, 4B, and 4C, the temperature of the outside air, and the temperature of the underfloor air 17 are relatively low. Therefore, even if the air conditioner 16 is not used, the underfloor air 17 Each room 4A, 4B and 4C can be effectively cooled (air-conditioned) using Therefore, an increase in air conditioning cost can be prevented. FIG. 24 is a flowchart illustrating an example of the processing procedure of the second supply step S347.

As shown in FIGS. 1 and 24, in the second supply step S347 of the present embodiment, first, the air volume of the fan 10B of the ventilation means 10 (total supply volume of the underfloor air 17) is set (step S911). The air volume of the fan 10B of the present embodiment is set to a fourth air volume (for example, 1000 m ³ / h), for example, because the natural ventilation is smaller than that 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 purification device 10C, and then each room 4A via the damper 20 (20a to 20c). Supplied to floor space 4 such as 4B and 4C.

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

  The difference Vb is obtained for each of the living rooms 4A, 4B, and 4C. Difference Vb of this embodiment is calculated | required as a value which deducted target temperature from the temperature of each room 4A, 4B, and 4C similarly to passive heating mode S24. The smaller this value (difference Vb), the lower the temperature of each of the rooms 4A, 4B and 4C.

  Next, in 2nd supply step S347, the opening degree of the damper 20 (20a-20c) of each room 4A, 4B, and 4C is adjusted based on the said difference Vb of each room 4A, 4B, and 4C (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, 4B, and 4C having higher temperatures, the living rooms 4A, 4B, and 4C can be efficiently cooled.

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

  Further, the damper 20 (20a to 20c) of the living room 4A, 4B, or 4C in which the difference Vb is + 0.5 ° C. to + 1.5 ° C. is set to a fourth opening that is larger than the third opening (step) S917). The damper 20 of the room 4A, 4B, or 4C where the difference Vb is greater than + 1.5 ° C. is set to a fifth opening that is larger than the fourth opening (step S918).

  And it is judged whether the opening degree of the damper 20 (20a-20c) of all the living rooms 4A, 4B, and 4C was adjusted (step S919). When it is determined that the openings of the dampers 20 of all the living rooms 4A, 4B, and 4C have been adjusted, the next step S348 (shown in FIG. 23) is performed. On the other hand, when it is judged that the opening degree of the dampers 20 of all the living rooms 4A, 4B and 4C is not adjusted, the dampers 20 of the other living rooms 4A, 4B and 4C are selected (step S920), and steps S913 to step S913. S919 is performed again. Thereby, the opening degree of the damper 20 of all the living rooms 4A, 4B, and 4C can be adjusted based on the difference Vb. Accordingly, the supply amount of the underfloor air 17 to the living rooms 4A, 4B, and 4C 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 changed as appropriate according to the air volume of the ten fans 10B. Further, the difference Va of the present embodiment may be obtained as a value obtained by subtracting the temperature of each of the living rooms 4A, 4B, and 4C from the target temperature, for example.

  Next, in the passive cooling mode S34, the supply of the underfloor air 17 to the living rooms 4A, 4B, and 4C 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 20c) of the living rooms 4A, 4B, and 4C set in the second supply step S347 due to such remaining, each living room 4A, 4B and 4C 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 rooms 4A, 4B, and 4C is lower than a predetermined temperature (step S349). About "predetermined temperature" of each living room 4A, 4B, and 4C, it can set suitably. The temperature of the present embodiment is set to 28 ° C., for example, based on the target temperature (28 ° C.) set in the second supply step S347.

  When the temperature (28 ° C.) of each of the living rooms 4A, 4B, and 4C 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, 4B, and 4C is equal to or higher than the temperature (that is, the temperature of at least one of the rooms 4A, 4B, and 4C is equal to or higher than the temperature) ("N" in step S349), the underfloor air 17 Even if it uses, it can be judged that each living room 4A, 4B and 4C cannot be cooled effectively. In this case, the passive cooling mode S34 is interrupted, and the cooling mode S33 (shown in FIGS. 16 and 17) is performed. Thus, in this embodiment, even when the underfloor air 17 is supplied to each of the rooms 4A, 4B, and 4C for a certain period of time, when it is determined that the rooms 4A, 4B, and 4C are not sufficiently cooled, the passive cooling mode S34 is interrupted, and the cooling mode S33 is quickly performed. Accordingly, the living rooms 4A, 4B, and 4C 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). When it is determined that the current period is the second period (“Y” in step S350), steps S345 to S350 are performed again. Thereby, in the second period (summer passive period), each room 4A, 4B and 4C can be effectively cooled (air-conditioned) using only natural energy without using the air conditioner 16. Increase in air conditioning 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 of 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, 4B, and 4C 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 processing 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 S24 and the cooling mode S33 are included, the living rooms 4A, 4B, and 4C can be comfortably air-conditioned throughout the year using the air conditioner 16. . Furthermore, in the heating mode S24 and the cooling mode S33, the supply amount of warm air or cold air can be individually adjusted based on the temperature difference between the temperature of each room 4A, 4B, and 4C and the target temperature. 4B and 4C can be efficiently cooled and heated. In addition, since the air conditioning method of the present embodiment includes the passive heating mode S24 and the passive cooling mode S34, the living rooms 4A, 4B, and 4C 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, 4B, and 4C become overdried in winter.

  In the present embodiment, the mode in which only one air conditioner 16 is provided in the underfloor space 3 is exemplified, but the present invention is not limited to this. For example, two or more air conditioners 16 may be provided in the underfloor space 3. In addition to the air conditioner 16 provided in the underfloor space 3, an air conditioner (not shown) may be separately provided in each of the living rooms 4A, 4B, and 4C.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
