  The present embodiment relates to a control device for an air conditioning system and an air conditioning system. Specifically, this embodiment includes a control device for an air conditioning system provided in an air conditioning system that blows out cold air or warm air from a plurality of air outlets provided in a conditioned space of a building toward a plurality of air conditioning regions, and the control device. It relates to air conditioning systems.

  In embodiment described below, the case where a building is a detached house is assumed and the case where an air conditioning system is a whole building air conditioning system is assumed. This entire building air conditioning system is configured to supply heat energy generated by a heat source machine to the entire building as cold air or warm air. The entire building air conditioning system is configured to perform air conditioning and ventilation.

  An air conditioning system 10 illustrated in FIG. 1 is installed in a building 20 and includes a heat source device 11, an air filter 12, and a transport fan 13. In addition, the air conditioning system 10 illustrated in FIG. 1 includes five dampers 14 and five air outlets 15 for one transport fan 13. Since the dampers 14 and the air outlets 15 correspond one to one, the number of the dampers 14 and the air outlets 15 is the same. The damper 14 here is realized by a VAV unit (VAV: Variable Air Volume). The number of transport fans 13 and the number of dampers 14 and outlets 15 are appropriately determined according to the capacity of the heat source unit 11, the configuration and scale of the building 20, and the like. The number of dampers 14 is preferably 5 to 7 with respect to one transport fan 13.

  In addition, the air conditioning system 10 includes an air supply duct 16 that sends out air that sends cold air or warm air from the heat source device 11 to the air outlet 15, and an outside air duct 171 that introduces outside air into the heat source device 11. The air inside the building 20 is also introduced into the heat source unit 11. In FIG. 1, a path for introducing the air inside the building 20 to the heat source unit 11 is denoted by reference numeral 172. This path 172 schematically represents the flow of air, and includes locations where air flows, such as door gaps and ventilation openings inside the building 20. The path 172 may include a reflux duct.

  The air sent out by the heat source unit 11 includes cold air cooled by the heat source unit 11 and warm air heated by the heat source unit 11 in accordance with the operation state of the heat source unit 11. Further, the air conditioning system 10 shown in FIG. 1 includes a control device 30 and five temperature sensors 18. Here, the heat source device 11, the air filter 12, and the transport fan 13 are accommodated in a single casing 101 installed in the building 20 and are unitized. Therefore, a path (shown by a broken line in FIG. 1) from the heat source device 11 through the air filter 12 to the transport fan 13 is formed inside the housing 101.

  The air conditioning system 10 includes an air supply duct 16, a transport fan 13, and five dampers 14 in order to distribute the thermal energy generated by the heat source device 11 to the five outlets 15. The air sent out by the transport fan 13 is sent to the air outlet 15 through the air supply duct 16. That is, the conveyance fan 13, the five dampers 14, and the air supply duct 16 constitute a distribution device 102 that distributes the thermal energy generated by the heat source device 11 to the five outlets 15. The ratio at which the heat energy generated by the heat source device 11 is distributed to the five air outlets 15 is determined by the air volume of the transport fan 13 and the opening degree of each of the five dampers 14. That is, when the control device 30 controls the distribution device 102, a ratio of distributing the thermal energy generated by the heat source device 11 to the five outlets 15 is determined.

  Each of the five air outlets 15 is provided in one of the four air-conditioned spaces 21 in the building 20. That is, air is supplied from the outlet 15 to each of the four air-conditioned spaces 21. The air outlet 15 is installed on the ceiling surface or wall surface of the air-conditioned space 21. The air-conditioned space 21 is a space to be air-conditioned such as a living room, a kitchen, and a Western-style room. The air-conditioned space 21 is not limited to a room, and may be a hallway or a staircase. The amount of heat supplied from the air outlet 15 to each of the plurality of air-conditioned spaces 21 per unit time is determined by the temperature and flow rate of air supplied from the air outlet 15 to the air-conditioned space 21.

  The air-conditioned space 21 includes an air-conditioned space 21A in which two or more air outlets 15 are provided and an air-conditioned space 21B in which one air outlet 15 is provided. FIG. 1 shows one conditioned space 21A and three conditioned spaces 21B. Two air outlets 15 are provided in the air-conditioned space 21A of FIG.

  In the air-conditioned space 21A in which the two air outlets 15 are provided, there are two air-conditioned areas 211 and 212. The number of air outlets 15 in the air-conditioned space 21A is the same as the number of air-conditioned areas in the air-conditioned space 21A. Then, the two air outlets 15 of the air-conditioned space 21A blow out cold air or warm air toward the two air-conditioned regions 211 and 212, respectively (see FIG. 4).

  In the air-conditioned space 21B provided with one air outlet 15, the air-conditioned space 21B is one air-conditioned area. That is, the air outlet 15B of the air-conditioned space 21B uses the air-conditioned space 21B as an air-conditioned area and blows out cool air or warm air toward the air-conditioned area. In FIG. 1, air-conditioned areas 213, 214, and 215 are set for the three air-conditioned spaces 21B, respectively.

  Further, a temperature sensor 18 is installed in each of the air conditioning regions 211 to 215. Each temperature sensor 18 is preferably housed in a case having a vent so as to measure the temperature without being affected by radiant heat. The place where the temperature sensor 18 is arranged is determined so that the air blown out from the outlet 15 does not directly hit the temperature sensor 18.

  Even when one conditioned space 21 is divided into a plurality of conditioned areas, one temperature sensor 18 may be installed in one conditioned space 21. For example, it is assumed that the living room and the second-floor corridor are connected by an atrium, three outlets 15 are provided in the living room, and two outlets 15 are provided in the second-floor corridor. In this case, one temperature sensor 18 may be installed in the living room, and one temperature sensor 18 may be installed in the hallway on the second floor.

  As described above, the five outlets 15, the five air-conditioning areas 211 to 215, and the five temperature sensors 18 correspond to each other one to one. The control device 30 acquires the temperature measured by each of the temperature sensors 18 as the current temperature of each of the air-conditioning areas 211 to 215 every predetermined time. And the control apparatus 30 controls the heat-source equipment 11 and the distribution apparatus 102 based on each current temperature of the air-conditioning area | region 211-215, and distribution of the calorie | heat amount per unit time to each of the five blower outlets 15 Adjust the amount.

  The heat source unit 11 is a heat pump type air conditioner including one indoor unit 111 and one outdoor unit 112, and air from the indoor unit 111 is supplied to the air-conditioned space 21 through the air supply duct 16. Moreover, the air taken in by the indoor unit 111 is outdoor air taken in from the underfloor 22 of the building 20 through the outside air duct 171 and indoor air collected from the inside of the building 20 through the path 172. The outside air duct 171 is connected to a ventilation fan 19 that takes in air under the floor 22.

  The heat source unit 11 performs a cooling operation in which cool air is sent out from the indoor unit 111 in summer, and performs a heating operation in which warm air is sent out from the indoor unit 111 in winter. Switching between the cooling operation and the heating operation of the heat source unit 11 is performed in an intermediate period such as spring or autumn. The difference between the cooling operation and the heating operation is whether the set temperature of the heat source device 11 is used as an upper limit value or a lower limit value. The heat source unit 11 operates so that the temperature of the cool air sent out from the indoor unit 111 during the cooling operation does not exceed the set temperature of the heat source unit 11 that is the upper limit value, and the warm air sent out from the indoor unit 111 during the heating operation Is operated so as not to fall below the set temperature of the heat source unit 11 which is the lower limit value. In the following description, the amount of heat at the time of heating operation means the amount of heat of warm air, and the amount of heat at the time of cooling operation means the amount of heat of cold air.

  Air from the indoor unit 111 is sent to the air supply duct 16 through the air filter 12. The air filter 12 is preferably a HEPA filter (HEPA: High Efficiency Particulate Air). If the air filter 12 is a HEPA filter, it is possible to remove fine particulate matter. Here, dust, insects, and the like, which are relatively large in size, are introduced before air is introduced into the air filter 12 by a filter disposed at one or more places in a path including the ventilation fan 19, the outside air duct 171, and the indoor unit 111. Removed. Therefore, clogging of the air filter 12 is suppressed.

  In the air conditioning system 10, the air sent from the indoor unit 111 and passed through the air filter 12 and then sent to the transport fan 13 is introduced into the air supply duct 16. The transport fan 13 accelerates air from the indoor unit 111. In the air conditioning system 10, the air supply duct 16 includes a branch duct 161 branched into five systems. That is, the air from the indoor unit 111 is introduced into the five branch ducts 161.

  A damper 14 is disposed in each of the five systems of branch ducts 161. The damper 14 can be adjusted in opening degree, and changes the flow rate of air passing through the branch duct 161 by changing the opening degree. An outlet 15 is connected to the end of the branch duct 161. Therefore, the air from the indoor unit 111 is sent to the damper 14 through the transport fan 13, and after the flow rate is adjusted by the damper 14, the air is blown out to each of the air-conditioning regions 211 to 215 through the air outlet 15.

  The air conditioning system 10 described above constantly ventilates the building 20. Therefore, in principle, the transport fan 13 always operates. Further, the air conditioning system 10 stops the heat source device 11 when the cooling operation or the heating operation is not required. That is, the air introduced into the indoor unit 111 from the outside air duct 171 is sent to the conditioned space 21 by the transport fan 13 for ventilation even when the heat source unit 11 does not cool or heat. However, it is possible to stop the conveyance fan 13 as necessary for maintenance or the like. Moreover, when performing ventilation with a ventilation fan etc., the conveyance fan 13 may be stopped.

  Below, the control apparatus 30 is explained in full detail. As illustrated in FIG. 2, the control device 30 includes a processing unit 31 and a control unit 32. The processing unit 31 determines a distribution amount of heat supplied from each of the plurality of air outlets 15 to each of the plurality of air-conditioned spaces 21. The control unit 32 controls the heat source device 11, the transport fan 13, and the damper 14. In addition, the control device 30 includes an interface unit 33 for inputting and outputting information to and from the operation display device 40.

  The operation display device 40 includes a touch panel including a display device and a touch pad, and functions as a user interface (GUI: Graphic User Interface). That is, the control device 30 outputs information to the display device included in the operation display device 40 and receives information input from the touch pad included in the operation display device 40. Various screens are displayed on the operation display device 40 as necessary. The operation display device 40 may not be dedicated but may be a smartphone, a tablet computer, a personal computer, or the like. Further, instead of the operation display device 40, a display device and an operation device may be provided separately.

  The screen displayed on the operation display device 40 includes a screen for associating the damper 14 with each of the air conditioning regions 211 to 215, a screen for associating the temperature sensor 18 with each of the air conditioning regions 211 to 215, and the like. When the correspondence relationship between each of the air-conditioning regions 211 to 215 and the damper 14 is determined and the correspondence relationship between each of the air-conditioning regions 211 to 215 and the temperature sensor 18 is determined, each of the air-conditioning regions 211 to 215, the damper 14, and the temperature sensor 18 are determined. Are tied together. Moreover, since the blower outlet 15 respond | corresponds with the damper 14 on a one-to-one basis, if the corresponding relationship between each of the air-conditioning areas 211 to 215 and the damper 14 is determined, each of the air-conditioned areas 211 to 215 and the blower outlet 15 are connected. .

  By the way, one of the screens displayed on the operation display device 40 is a screen P1 for determining each user desired temperature in the air-conditioned space 21 as shown in FIG. The screen P1 includes a plurality of button groups B1, B2, and B3 that receive user desired temperatures of the plurality of conditioned spaces 21. The screen P1 is provided with a field F1 indicating the name of the air-conditioned space 21 (for example, a room name). In the example shown in FIG. 3, it is possible to determine the user desired temperatures of the three air-conditioned spaces 21 on one screen P1. When the number of conditioned spaces 21 provided in the building 20 exceeds the number of conditioned spaces 21 that can be displayed on one screen P1, a button for switching to another screen is displayed on the screen P1. When this button is operated, the screen is switched to another screen, and the user desired temperature of the other air-conditioned space 21 can be set. The user desired temperature is used for a target temperature setting process described later in the processing unit 31 of the control device 30.

  In the example shown in FIG. 3, the button group B1 includes three buttons B10, B11, and B12 arranged vertically. The center button B10 corresponds to a reference temperature set for one building 20 as a whole. The reference temperature can be set by the user. In the air conditioning system 10, an initial value of the reference temperature may be set at the time of factory shipment. When this button B10 is operated, the user desired temperature is set to the reference temperature. When the upper button B11 is operated, the user desired temperature is set higher than the reference temperature, and when the lower button B12 is operated, the user desired temperature is set lower than the reference temperature. When the button B11 or the button B12 is operated, the control device 30 changes the user desired temperature at predetermined temperature increments for each operation. The selected temperature is displayed numerically in association with the button group B1.

  As an example, it is assumed that the reference temperature is 26.0 [° C.], the predetermined temperature is 0.5 [° C.], and the user desired temperature is the reference temperature. In this case, when the button B11 is operated once, the user desired temperature is set to 26.5 [° C.], and when the button B12 is operated once, the user desired temperature is set to 25.5 [° C.]. If the user desired temperature is the reference temperature and the button B11 is operated twice, the user desired temperature is set to 27.0 ° C. Regardless of the set user desired temperature, when the button B10 is operated, the user desired temperature returns to the reference temperature of 26.0 [° C.]. The numerical value shown here is an example when the air-conditioning system 10 is in the period of the cooling operation, and is not intended to be limited to these numerical values.

  Here, the configuration and operation of the button group B1 have been described. The button groups B2 and B3 have the same configuration and operation. Moreover, although the structure which enables the user desired temperature of the three air-conditioned spaces 21 to be set on one screen was illustrated, the number of air-conditioned spaces 21 on which the user desired temperature is set on one screen can be changed by design. Furthermore, the configurations and operations of the button groups B1, B2, and B3 are not limited to the configurations described above. For example, each of the plurality of button groups B1, B2, and B3 may include five buttons. In this configuration, in each of the plurality of button groups B1, B2, and B3, a button corresponding to the selected user desired temperature may be set to a display state different from the remaining buttons. Different display states are realized by at least one element such as a button size, a button color, and a mark added to the button.

  When the user desired temperature is determined for each of the plurality of conditioned spaces 21 using the screen P <b> 1, the control device 30 stores the user desired temperature in the storage unit 34. The storage unit 34 stores user desired temperatures for each of the plurality of air-conditioned spaces 21.

  Normally, the processing unit 31 of the control device 30 sets the user desired temperature stored in the storage unit 34 as the target temperature. That is, the user desired temperature of each of the plurality of conditioned spaces 21 stored in the storage unit 34 becomes the target temperature corresponding to each of the plurality of conditioned spaces 21. When the processing unit 31 is operating in the energy saving mode or the like, the user desired temperature may be corrected to the energy saving side, and the corrected temperature may be used as the target temperature.

  In the air-conditioned space 21 </ b> A provided with two air outlets 15, the air-conditioned space 21 </ b> A is composed of two air-conditioned areas 211 and 212. In this case, the target temperature set in the air-conditioned space 21A is associated with each of the air-conditioned areas 211 and 212. That is, a common target temperature is set for each of the two air-conditioned areas 211 and 212 of the air-conditioned space 21A.

  In the air-conditioned space 21B provided with one air outlet 15, the air-conditioned space 21B is one air-conditioned area, so the target temperature and the air-conditioned area are associated one-to-one. That is, each target temperature of the air-conditioned areas 213, 214, and 215 becomes the target temperature of the corresponding air-conditioned space 21B.

  The processing unit 31 of the control device 30 illustrated in FIG. 2 includes an acquisition unit 310 that communicates with each of the plurality of temperature sensors 18. In the air conditioning system 10, the acquisition unit 310 is configured to perform wired communication with the temperature sensor 18 and periodically inquire the plurality of temperature sensors 18 about the current temperature. That is, the acquisition unit 310 acquires the current temperature from each temperature sensor 18 by polling the plurality of temperature sensors 18. The period at which the acquisition unit 310 inquires each of the plurality of temperature sensors 18 about the current temperature is set in a range of 1 minute to 15 minutes, preferably in a range of 5 minutes to 10 minutes. This period is determined by the measurement accuracy of the temperature sensor 18, the speed at which the temperature changes, and the like.

  The current temperature acquired by the acquisition unit 310 from the temperature sensor 18 is a temperature measured by the temperature sensor 18 when the acquisition unit 310 makes an inquiry to the temperature sensor 18. However, the average value of the temperature in a predetermined period set near the time when the temperature sensor 18 receives an inquiry from the acquisition unit 310 may be used. This predetermined period is either before or after the time when the temperature sensor 18 receives an inquiry from the acquisition unit 310, or straddles the time. This predetermined period is set in a range of, for example, 10 seconds to 3 minutes, preferably in a range of 30 seconds to 1 minute.

  The processing unit 31 of the control device 30 includes a temperature calculation unit 311 and a determination unit 312 in addition to the acquisition unit 310. Here, for the sake of explanation, the numbers at the end of the air conditioning areas 211 to 215 are assumed to be identification information j of the air conditioning area. That is, the identification information j of the air conditioning area 211 is 1, the identification information j of the air conditioning area 212 is 2, the identification information j of the air conditioning area 213 is 3, and the identification information j of the air conditioning area 214 is 4. The identification information j of the air conditioning area 215 is 5.

  The temperature calculation unit 311 sets the user desired temperature of each of the plurality of conditioned spaces 21 stored in the storage unit 34 as each target temperature of the conditioned regions 211 to 215. Then, the temperature calculation unit 311 calculates the temperature difference between the target temperature and the current temperature with the target temperature and the current temperature acquired by the acquisition unit 310 as inputs for each of the air conditioning regions 211 to 215. This temperature difference is a temperature difference at each measurement point in the air-conditioning areas 211 to 215 when the installation location of each temperature sensor 18 in the air-conditioning area 211 to 215 is a measurement point. In particular, two temperature sensors 18 are installed in the air-conditioned space 21A, and the installation locations of these two temperature sensors 18 are set as measurement points 51 and 52, respectively.

  First, during the cooling operation in which the heat source device 11 generates cold air and the cold air is blown out from the blowout port 15, the temperature calculation unit 311 calculates the temperature difference as follows. When the current temperature acquired by the acquisition unit 310 is represented by θj1 and the target temperature is represented by θj2 for the air conditioning region whose identification information is j, the temperature calculation unit 311 calculates the temperature difference Δθj of this air conditioning region as Δθj = θj1−. Obtained by the calculation of θj2 and output with a positive / negative sign.

  Moreover, the temperature calculation part 311 calculates a temperature difference as follows at the time of the heating operation in which the heat source machine 11 produces | generates warm air and warm air blows off from the blower outlet 15. FIG. When the current temperature acquired by the acquisition unit 310 is represented by θj1 and the target temperature is represented by θj2 for the air conditioning region whose identification information is j, the temperature calculation unit 311 calculates the temperature difference Δθj of the measurement points in the air conditioning region as Δθj. = [Theta] j2- [theta] j1 is calculated and output with a positive or negative sign.

  The temperature calculation unit 311 obtains a temperature difference Δθj for each measurement point in the air conditioning regions 211 to 215. The temperature difference Δθj obtained by the temperature calculation unit 311 is temporarily stored in the storage unit 34 in association with each identification information j of the air conditioning regions 211 to 215. The temperature difference Δθj stored in the storage unit 34 is updated when the acquisition unit 310 acquires the current temperature θj1.

  The determination unit 312 determines the amount of heat to be supplied from the heat source device 11 to the air outlets 15 of the air conditioning regions 211 to 215 using the temperature difference Δθj between the measurement points of the air conditioning regions 211 to 215. The amount of heat distributed to each of the air outlets 15 in the air conditioning regions 211 to 215 is determined by the opening degree of each damper 14, the air volume of the transport fan 13, and the amount of heat generated by the heat source unit 11 per unit time. The determining unit 312 determines the opening degree of each damper 14 based on the temperature differences Δθj of the measurement points in the air-conditioning areas 211 to 215, and then the air volume of the transport fan 13 and the amount of heat generated by the heat source unit 11 per unit time. Determine.

  The air conditioning control in the air conditioning system 10 includes basic air conditioning control and priority air conditioning control.

  Basic air conditioning control is performed as follows. Below, after explaining the function which determines the opening degree of the damper 14, based on the opening degree of all the dampers 14 arrange | positioned in the building 20, the air volume of the conveyance fan 13 and the calorie | heat amount which the heat source machine 11 produces | generates per unit time The function that defines The function of determining the opening degree of the damper 14 will be described by omitting the identification information j of the air conditioning region.

  When the air conditioning system 10 is in a cooling operation, if the current temperature exceeds the target temperature, the cool air from the heat source device 11 must be supplied to the air-conditioned space 21 and the current temperature must be maintained near the target temperature. In the cooling operation, the fact that the current temperature is higher than the target temperature in the air-conditioned space 21 indicates that the cooling is insufficient. Further, in the air-conditioned space 21, the current temperature approaching the target temperature indicates that the cooling is sufficient, and that the current temperature is below the target temperature indicates that the cooling is excessive.

  When the cooling is insufficient, it is necessary to increase the amount of heat of the cool air supplied to the conditioned space 21 per unit time as the current temperature is higher than the target temperature. In other words, if the cooling is insufficient, it can be said that the greater the current temperature exceeds the target temperature and the greater the difference between the current temperature and the target temperature, the greater the degree of cooling shortage.

  When the air conditioning system 10 is in cooling operation, the temperature calculation unit 311 obtains a temperature difference obtained by subtracting the target temperature from the current temperature with a positive or negative sign. Therefore, if the temperature difference calculated by the temperature calculation unit 311 is positive, it indicates that the cooling is insufficient, and the greater the temperature difference Δθ, the greater the degree of cooling.

  Further, when the air conditioning system 10 is in the heating operation, if the current temperature is lower than the target temperature, the warm air from the heat source device 11 must be supplied to the air-conditioned space 21 and the current temperature must be maintained near the target temperature. In the heating operation, the fact that the current temperature is lower than the target temperature in the air-conditioned space 21 indicates that heating is insufficient. In the air-conditioned space 21, the current temperature approaching the target temperature indicates that heating is sufficient, and that the current temperature exceeds the target temperature indicates that heating is excessive.

  When heating is insufficient, it is necessary to increase the amount of heat of warm air supplied to the conditioned space 21 per unit time as the current temperature is lower than the target temperature. In other words, if the heating is insufficient, it can be said that the degree of the shortage of heating is larger as the current temperature is lower than the target temperature and the difference between the current temperature and the target temperature is larger.

  When the air conditioning system 10 is in the heating operation, the temperature calculation unit 311 obtains a temperature difference obtained by subtracting the current temperature from the target temperature with a positive / negative sign. Therefore, if the temperature difference obtained by the temperature calculation unit 311 is positive, it indicates that the heating is insufficient, and the larger the temperature difference Δθ is, the greater the degree of heating is.

  Therefore, the processing unit 31 includes a first control table 313 having a format as shown in Table 1 in which the temperature difference Δθ and the opening degree are associated with each other. In the first control table 313, the temperature difference is divided into a plurality of sections, and the opening degree of the damper 14 corresponds to each of the plurality of sections. In the first control table 313 of Table 1, there are provided more sections where the temperature difference Δθ is positive than sections where the temperature difference Δθ is negative.

  As an example, the first control table 313 defines five sections at intervals of 1 [° C.] with respect to the temperature difference Δθ. In the first control table 313, a relatively large opening corresponds to the section where the temperature difference Δθ is positive and is relatively large. That is, in the first control table 313, when air conditioning is insufficient (cooling or heating is insufficient), the greater the degree of shortage, the greater the amount of cold heat supplied to the air-conditioned space 21 per unit time. The opening degree of the damper 14 is set.

  In the first control table 313 shown in Table 1, even if the air conditioning is excessive, the amount of heat is supplied so that the temperature of the air-conditioned space 21 does not fluctuate to the uncomfortable side until the current temperature is 1 [° C.] away from the target temperature. Thus, the opening degree of the damper 14 is set (25 [%]). Further, in the first control table 313 shown in Table 1, when the temperature difference exceeds +2 [° C.], the opening degree of the damper 14 is determined to be maximized (100 [%]). Further, in the first control table 313 shown in Table 1, when air conditioning is excessive, if the current temperature exceeds 1 [° C.] from the target temperature, the opening degree of the damper 14 is determined to be minimum. (5 [%]). The minimum opening of the damper 14 is determined so that the minimum degree of ventilation can be secured in the air-conditioned space 21. However, the damper 14 may be closed if the air-conditioned space 21 can be ventilated even when the transport fan 13 is stopped. In this case, the opening degree of the damper 14 is 0 [%].

  In the above-described operation, when the acquisition unit 310 acquires the current temperature of each of the plurality of conditioned spaces 21, the determination unit 312 determines the opening degree of the damper 14 corresponding to each of the conditioned regions of the plurality of conditioned spaces 21. The determination unit 312 determines the air volume of the transport fan 13 after determining the opening degree of the damper 14 in order to determine the amount of heat per unit time to be allocated to each of the air-conditioned areas of the plurality of air-conditioned spaces 21. The air volume of the transport fan 13 can be selected from a plurality of stages. In the air conditioning system 10, the air volume of the transport fan 13 is selected from four stages.

  In the air conditioning system 10, since the five dampers 14 are associated with the transfer fan 13, the determination unit 312 determines the air volume of the transfer fan 13 based on the opening degree of the five dampers 14. The air volume of the transport fan 13 is associated with the opening degree of the damper 14 in advance. After determining the opening degree of each of the five dampers 14 corresponding to the conveying fan 13, the determining unit 312 determines the air volume of the conveying fan 13 so as to correspond to the total or average of the opening degree of each of the five dampers 14. Determine.

  If the air conditioning system 10 is in cooling operation, the set temperature of the heat source device 11 is set to a temperature lower than the lowest temperature among the target temperatures of the plurality of conditioned spaces 21. Moreover, if the air conditioning system 10 is a heating operation, the set temperature of the heat source device 11 is set to a temperature higher than the highest temperature among the target temperatures of the plurality of air-conditioned spaces 21. This temperature is set to a value obtained by adding an appropriate temperature to the highest temperature among the target temperatures of the plurality of air-conditioned spaces 21. The temperature added to the maximum temperature is selected from the range of 1 [° C.] or more and less than 7 [° C.], and is set to 4 [° C.] as an example. When the set temperature of the heat source unit 11 is determined, the amount of heat that the heat source unit 11 supplies per unit time is adjusted by the air volume. Therefore, the determination unit 312 determines the air volume of the heat source device 11 according to the air volume of the transport fan 13. Further, the determination unit 312 determines the air volume of the heat source device 11 so as to be close to the air volume of the transport fan 13.

  In the basic air conditioning control described above, the determination unit 312 determines the amount of heat supplied per unit time from each of the plurality of air outlets 15 based on the temperature difference between the measurement points of the air conditioned space 21 corresponding to each of the plurality of air outlets 15. Has been decided.

  Air conditioning control based on the first control table 313 described above is basic air conditioning control. However, the control device 30 further performs priority air conditioning control based on the second control table 314 for the air conditioning control of the air conditioning space 21 </ b> A configured by the two air conditioning regions 211 and 212.

  FIG. 4 shows an outline of the air-conditioned space 21A. The air-conditioned space 21A is a living room of the building 20 and has an atrium structure. That is, the ceiling of the air-conditioned space 21A is substantially the same height as the ceiling of the air-conditioned space 21B on the second floor, and is a space that is wider in the vertical direction than the standard room. Two air outlets 15 are provided in the air-conditioned space 21A, and the two air outlets 15 are referred to as a first air outlet 151 and a second air outlet 152, respectively. The 1st blower outlet 151 blows off cold air or warm air toward the air-conditioning area | region 211 below the air-conditioned space 21A. The 2nd blower outlet 152 blows off cold air or warm air toward the air-conditioning area | region 212 above 21 A of air-conditioning spaces.

  The air-conditioned area 211 is the floor side of the air-conditioned space 21A, and is an area where people in the air-conditioned space 21A exist. The air-conditioned area 212 is the ceiling side of the air-conditioned space 21A and is an area above the person in the air-conditioned space 21A. Therefore, in consideration of human comfort in the air-conditioned space 21 </ b> A, it is preferable that the air-conditioning environment in the air-conditioning area 211 has priority over the air-conditioning environment in the air-conditioning area 212.

  Therefore, the measurement point 51 that is the installation location of the temperature sensor 18 in the air conditioning region 211 is set as the priority measurement point 51. Further, the measurement point 52 that is the installation location of the temperature sensor 18 in the air-conditioning region 212 is set as a non-priority measurement point 52. In addition, it is preferable that the priority measurement point 51 (the installation location of the temperature sensor 18 in the air-conditioned area 211) is set to a height of about 1.0 to 1.2 m from the floor surface of the air-conditioned space 21A. Further, the non-priority measurement point 52 (the location where the temperature sensor 18 is installed in the air-conditioning area 212) is preferably set to a height of about 1.0 to 1.2 m from the floor surface of the second floor room of the building 20. .

  The determining unit 312 brings the current temperature of the priority measurement point 51 close to the target temperature when determining the amount of heat supplied per unit time from the first outlet 151 and the second outlet 152 in the air-conditioned space 21A. This has a function of prioritizing the current temperature of the non-priority measurement point 52 closer to the target temperature.

  Therefore, the processing unit 31 includes a second control table 314 having a format as shown in Table 2. The second control table 314 defines the relationship between the temperature difference Δθ1 at the priority measurement point 51, the temperature difference Δθ2 at the non-priority measurement point 52, and each air conditioning control using the first outlet 151 and the second outlet 152. doing.

  In the second control table 314, “151: normal” means that the determining unit 312 determines the amount of heat supplied from the first outlet 151 per unit time according to the temperature difference Δθ1 of the priority measurement point 51. Indicates. In the second control table 314, “152: normal” is determined by the determining unit 312 according to the temperature difference Δθ2 of the non-priority measurement point 52 and determines the amount of heat supplied from the second outlet 152 per unit time. It shows that. That is, the “normal” air conditioning control is the same as the basic air conditioning control with reference to the first control table.

  In the second control table 314, “151: first assistance” indicates the amount of heat that the determining unit 312 supplies per unit time from the first outlet 151 according to the temperature difference Δθ2 of the non-priority measurement point 52. Indicates to decide. In the second control table 314, “152: second auxiliary” determines the amount of heat that the determination unit 312 supplies per unit time from the second outlet 152 according to the temperature difference Δθ1 of the priority measurement point 51. Indicates to do.

  That is, in the “first auxiliary” air conditioning control, the non-priority measurement point 52 becomes the first measurement point, and the priority measurement point 51 becomes the second measurement point. In the “first auxiliary” air conditioning control, the determination unit 312 refers to the first control table 313 and determines the opening degree of the damper 14 corresponding to the air conditioning region 211 according to the temperature difference Δθ2 of the air conditioning region 212. Ask. In the “second auxiliary” air conditioning control, the priority measurement point 51 is the first measurement point, and the non-priority measurement point 52 is the second measurement point. In the “second auxiliary” air conditioning control, the determination unit 312 refers to the first control table 313 and determines the opening degree of the damper 14 corresponding to the air conditioning region 212 according to the temperature difference Δθ1 of the air conditioning region 211. Ask.

  In the second control table 314, T1 is a temperature difference threshold, and is preferably set within a range of + 1 ° C. to + 3 ° C., for example.

  And the determination part 312 determines each air-conditioning control using the 1st blower outlet 151 and the 2nd blower outlet 152 with reference to the 2nd control table 314. FIG. In Table 2, the temperature differences Δθ1 and Δθ2 can be rephrased as “insufficient”, respectively.

  In Table 2, when Δθ1 is larger than the threshold value T1 [° C.], the air conditioning in the air conditioning region 211 is insufficient. When Δθ2 is larger than the threshold value T1 [° C.], it indicates that air conditioning in the air conditioning region 212 is insufficient. Further, when Δθ1 is larger than 0 [° C.] and equal to or smaller than the threshold T1 [° C.], it indicates that the air conditioning in the air conditioning region 211 is satisfied. When Δθ2 is greater than 0 [° C.] and less than or equal to the threshold T1 [° C.], it indicates that the air conditioning in the air conditioning region 212 is satisfied. Moreover, when Δθ1 is 0 [° C.] or less, it indicates that the air conditioning in the air conditioning region 211 is excessive. When Δθ2 is 0 [° C.] or less, it indicates that the air conditioning in the air conditioning region 212 is excessive.

  First, when the temperature differences Δθ1 and Δθ2 between the priority measurement point 51 and the non-priority measurement point 52 exceed the threshold T1 [° C.], the determination unit 312 sets “151: normal” and “152: normal”. That is, when air conditioning is insufficient in both of the air conditioning regions 211 and 212, the determination unit 312 controls the air conditioning region 211 in a direction to eliminate the air conditioning shortage state of the air conditioning region 211, and Air-conditioning control of the air-conditioning area 212 is performed in a direction to eliminate the shortage state. In other words, each of the air-conditioning areas 211 and 212 is air-conditioning controlled independently of each other.

  When the temperature difference Δθ1 at the priority measurement point 51 exceeds the threshold T1 [° C.] and the temperature difference Δθ2 at the non-priority measurement point 52 is equal to or less than the threshold T1 [° C.], the determination unit 312 determines “151: normal” and “152: Second assistance”. That is, when air conditioning is insufficient in the air conditioning area 211 and air conditioning is sufficient or excessive in the air conditioning area 212, the determination unit 312 air-conditions the air conditioning areas 211 and 212 in a direction to eliminate the air conditioning shortage state in the air conditioning area 211, respectively. Control. In other words, when air conditioning is insufficient in the air conditioning area 211, the air conditioning area 212 is controlled in such a direction as to eliminate the air conditioning shortage state in the air conditioning area 211 even if air conditioning is sufficient or excessive in the air conditioning area 212. Therefore, the lack of air conditioning in the air conditioning area 211 is resolved, and as a result, the comfort of the person in the air conditioning area 211 is given priority over the air conditioning environment in the air conditioning area 212.

  In addition, when the temperature difference Δθ1 of the priority measurement point 51 exceeds 0 [° C.] and is equal to or less than the threshold T1 [° C.], and the temperature difference Δθ2 of the non-priority measurement point 52 exceeds the threshold T1 [° C.], the determination unit 312 , “151: First assistance” and “152: Normal”. That is, when air conditioning is satisfied in the air conditioning region 211 and air conditioning is insufficient in the air conditioning region 212, the determination unit 312 controls the air conditioning regions 211 and 212 in a direction to eliminate the air conditioning shortage state in the air conditioning region 212, respectively. To do. In other words, if air conditioning is insufficient in the air conditioning area 212, the air conditioning area 211 is controlled in such a direction as to eliminate the air conditioning shortage state in the air conditioning area 212 even if the air conditioning area 211 is satisfied. Therefore, the air-conditioning environment of the air-conditioning area 212 is improved within the range in which the comfort of the air-conditioning area 211 is maintained.

  Further, when the temperature difference Δθ1 of the priority measurement point 51 is 0 [° C.] or less and the temperature difference Δθ2 of the non-priority measurement point 52 exceeds the threshold T1 [° C.], the determination unit 312 determines “151: normal” and “ 152: Normal ”. That is, when air conditioning is excessive in the air conditioning region 211 and air conditioning is insufficient in the air conditioning region 212, the determination unit 312 controls the air conditioning region 211 in a direction to eliminate the excessive air conditioning state of the air conditioning region 211, Air-conditioning control of the air-conditioning area | region 212 is performed in the direction which eliminates the lack of air-conditioning of the air-conditioning area | region 212. In other words, each of the air-conditioning areas 211 and 212 is air-conditioning controlled independently of each other. Even when air-conditioning in the air-conditioning area 212 is insufficient, if air-conditioning in the air-conditioning area 211 is excessive, air conditioning in the air-conditioning area 212 is performed. The air conditioning area 211 is not air-conditioned in the direction to eliminate the shortage state. Therefore, the excessive state of the air conditioning area 211 is eliminated, and as a result, the comfort of the person in the air conditioning area 211 is given priority over the air conditioning environment of the air conditioning area 212.

  When the temperature differences Δθ1 and Δθ2 between the priority measurement point 51 and the non-priority measurement point 52 are equal to or less than the threshold value T1 [° C.], the determination unit 312 sets “151: normal” and “152: normal”. That is, when the air conditioning is sufficient or excessive in both of the air conditioning regions 211 and 212, the determination unit 312 determines whether the air conditioning region 211 is in a direction to maintain the sufficient air conditioning state of the air conditioning region 211 or to eliminate the excessive air conditioning state. The air conditioning is controlled. In addition, the determination unit 312 controls the air-conditioning area 212 in a direction in which the air-conditioning area 212 is maintained in a sufficient air-conditioning state or an air-conditioning excess state is eliminated. In other words, each of the air-conditioning areas 211 and 212 is air-conditioning controlled independently of each other.

  As described above, the control device 30 normally performs air-conditioning control so that the current temperature of each of the air-conditioning areas 211 and 212 approaches the target temperature, and generation of temperature unevenness in which the temperature in the air-conditioned space 21A becomes uneven. Is suppressed. However, when air conditioning in the air conditioning area 211, which is a person's living area, is insufficient and the comfort of the air conditioning area 211 is reduced, the control device 30 causes the air conditioning area 211 to improve the comfort of the air conditioning area 211. 212 is air-conditioned. That is, the control device 30 improves the comfort of the air conditioning region 211 having a higher priority than the air conditioning environment of the air conditioning region 212 having a lower priority.

  Moreover, if the control apparatus 30 can maintain the comfort of the air-conditioning area | region 211 with a high priority, it will use the air-conditioning control of the air-conditioning area | region 211 for the air-conditioning area | region 212, and the air-conditioning environment of the air-conditioning area | region 212 with a low priority will be used. Improve. However, if the comfort of the air conditioning area 211 is not maintained, the control device 30 does not control the air conditioning area 211 in order to improve the air conditioning environment of the air conditioning area 212. That is, the control device 30 performs air-conditioning control on the air-conditioning area 211 in a range in which the comfort of the air-conditioning area 211 with high priority is maintained, and improves the air-conditioning environment of the air-conditioning area 212 with low priority.

  Therefore, when two air-conditioning areas 211 and 212 are provided in one air-conditioned space 21 </ b> A, the control device 30 can perform air-conditioning control according to the priority of air-conditioning of the two air-conditioning areas 211 and 212. it can. As a result, the control device 30 can further improve the air conditioning efficiency in the air conditioned space 21A when the air conditioned space 21A includes a plurality of outlets 151 and 152.

  Further, the number of air-conditioned areas provided in one air-conditioned space 21A may be three or more. In this case, the control device 30 performs air-conditioning control according to the air-conditioning priority of each of the three or more air-conditioning areas, and improves the comfort of the air-conditioning areas with higher priority than the air-conditioning environment of the air-conditioning areas with lower priority. Improve. In addition, the control device 30 uses the air conditioning control of the air conditioning region having a high priority for the air conditioning region having a low priority, in the range in which the comfort of the air conditioning region having a high priority is maintained. Improve the air conditioning environment in the area.

  Further, the control device 30 may be provided so that each of a plurality of air-conditioning regions provided in one air-conditioned space 21A is arranged in the horizontal direction. In this case, the greater the number of people present in the air conditioning area, the higher the priority of the air conditioning area. It is preferable that the control device 30 sets the priority of each of the plurality of air-conditioning areas by detecting the number of people present in each of the plurality of air-conditioning areas using a human sensor or the like.

  Further, the processing unit 31 may include a second control table 314 having a format as shown in Table 3. In this case, the priority measurement point 51 and the non-priority measurement point 52 are simply referred to as measurement points 51 and 52 because the priorities are equal to each other. In Table 3, when the temperature difference Δθ1 at the measurement point 51 exceeds the threshold T1 [° C.] and the temperature difference Δθ2 at the measurement point 52 is 0 [° C.] or less, the determination unit 312 determines “151: normal” and “152 : "Normal" is different from Table 2. That is, the same air conditioning control is performed for each of the air conditioning regions 211 and 212.

  Therefore, when two air-conditioning areas 211 and 212 are provided in one air-conditioning space 21A, the control device 30 performs air-conditioning control with equal priority of air-conditioning in the two air-conditioning areas 211 and 212. Can do. In this case, one of the two air-conditioning areas 211 and 212 that has a sufficient air-conditioning capability assists the other that has no sufficient air-conditioning capability. As a result, the control device 30 can further improve the air conditioning efficiency in the air conditioned space 21A when the air conditioned space 21A includes a plurality of outlets 151 and 152.

  In addition, the air conditioning system 10 may provide three or more air conditioning areas having the same priority in one air conditioning space 21A. Further, the control device 30 may be provided so that each of a plurality of air-conditioning regions provided in one air-conditioned space 21A is arranged in the horizontal direction.

  The control device 30 described above is realized as a main hardware configuration of a device including a processor that executes a program. The device including the processor may be a micro processing unit (MPU) in which a semiconductor memory is separately provided, or a micro controller that is housed in a single package together with the semiconductor memory. The control device 30 preferably includes at least a RAM (Random Access Memory) as a memory, and at least one of a ROM (Read-Only Memory) and an EEPROM (Electrically Erasable Programmable Read-Only Memory).

  In addition to being provided in a state written in a ROM, the program may be provided by a computer-readable recording medium that is a recording medium such as an optical recording disk or a recording medium including a flash memory. The program may be provided through a telecommunication line such as the Internet or a mobile communication network. The program provided by the recording medium or the telecommunication line is preferably stored in a rewritable nonvolatile memory (for example, EEPROM).

  The building 20 is not limited to a detached house, but may be another building such as an apartment house or a store. Although the structure provided with the heat pump type heat source device 11 was illustrated as the air conditioning system 10, the air conditioning system 10 may be configured to pass hot water or cold water through a plurality of fan coil units. Further, the air conditioning system 10 may have a configuration in which an air conditioner is individually provided for each air conditioning region. In the air conditioning system 10 described above, a HEPA filter is employed as the air filter 12, but it does not prevent the air filter 12 having another configuration from being used. The number of the conveyance fans 13 described above, the number of dampers 14 and the outlets 15, the number of temperature sensors 18, the number of air-conditioned spaces 21, and the like are examples, and may be changed as appropriate. Further, the transport fan 13 is not an essential component of the air conditioning system 10. That is, the air conditioning system 10 may be configured such that the cold air or the warm air generated by the heat source device 11 is blown out from the air outlet 15 through the damper 14 without being accelerated.

  The opening degree of the damper 14 shown in Table 1 is an example, and is appropriately changed according to the specifications of the air conditioning system 10. For example, in Table 1, the value described as 70 [%] is set to an appropriate value in the range of 50 [%] to 90 [%], and the value described as 40 [%] is , 30 [%] or more and 60 [%] or less in the range. Further, the value described as 25 [%] is set to an appropriate value in the range of 15 [%] to 30 [%]. In Table 1, 5 [%] is set to an appropriate value in the range of 5 [%] to 10 [%] in consideration of the minimum ventilation amount of normal ventilation. In the case of performing continuous ventilation separately from the air conditioning system 10, the minimum value of the opening degree of the damper 14 may be 0 [%]. The range of numerical values described here is also an example, and is appropriately changed depending on the design.

  In Table 1, the minimum unit of the temperature difference interval is set to 1 [° C.], but the minimum unit of the temperature difference interval is appropriately in the range of 0.1 [° C.] to 1.5 [° C.]. It is still desirable if it is in the range of 0.1 [° C.] or more and 1.0 [° C.] or less. The number of sections in Table 1 is not limited to five and can be determined as appropriate.

  Further, in Table 1, the temperature difference interval is divided by 2 [° C.], 1 [° C.], 0 [° C.], and −1 [° C.], but the temperature difference interval can be appropriately determined. .

  In the above-described air conditioning system 10, the acquisition unit 310 performs wired communication with the temperature sensor 18, but may perform wireless communication, and even if wired communication and wireless communication are mixed in the building 20. Good. There are no particular restrictions on the communication protocol between the acquisition unit 310 and the temperature sensor 18. In the air conditioning system 10 described above, the acquisition unit 310 inquires each of the plurality of temperature sensors 18 about the current temperature, but the plurality of temperature sensors 18 transmits the current temperature to the acquisition unit 310 at an appropriate timing. There may be.

  The air-conditioned space 21A may have an atrium structure in which the second floor and the third floor of the building are connected. That is, the atrium structure is not limited to a structure that connects specific floors.

The control device 30 for the air conditioning system of the first aspect according to the above-described embodiment is changed from the plurality of air outlets 151 and 152 provided in the air conditioned space 21A of the building 20 to the plurality of air conditioned regions 211 and 212 in the air conditioned space 21A. It is a control apparatus with which the air-conditioning system 10 which blows off cold air or warm air respectively is provided. The control device 30 includes a processing unit 31 that determines the amount of heat supplied from the plurality of air outlets 151 and 152 to the conditioned space 21A by cold air or warm air. The processing unit 31 has the following functions.
The temperature difference between the current temperature and the target temperature of the plurality of measurement points 51 and 52 that are respectively provided in the plurality of air-conditioning regions 211 and 212 and correspond to the plurality of outlets 151 and 152, respectively, A function for obtaining temperature differences Δθ1 and Δθ2 of 51 and 52, respectively.
A function of determining the amount of heat supplied from the plurality of outlets 151 and 152 according to the temperature differences Δθ1 and Δθ2 of the plurality of measurement points 51 and 52, respectively.
The temperature difference of the first measurement point (one of 51, 52) among the plurality of measurement points 51, 52 is the temperature of the second measurement point (the other of 51, 52) of the plurality of measurement points 51, 52. A function of determining the amount of heat supplied from the air outlet corresponding to the second measurement point according to the temperature difference corresponding to the first measurement point when the difference is larger.

  Therefore, the control apparatus 30 can aim at the further improvement of the air-conditioning efficiency in the air-conditioning space 21A, when providing the several air outlets 151 and 152 in one air-conditioning space 21A.

  In the control device 30 for an air conditioning system according to the second aspect according to the embodiment, in the first aspect, the processing unit 31 includes an acquisition unit 310, a temperature calculation unit 311, and a determination unit 312. preferable. The acquisition unit 310 acquires the current temperature of each of the plurality of measurement points 51 and 52. The temperature calculation unit 311 obtains temperature differences Δθ1 and Δθ2 of the plurality of measurement points 51 and 52, respectively. The determination unit 312 determines the amount of heat supplied from the plurality of outlets 151 and 152 according to the temperature differences Δθ1 and Δθ2 of the plurality of measurement points 51 and 52, respectively. Then, when cold air is blown out from the plurality of outlets 151, 152, the temperature calculation unit 311 obtains values obtained by subtracting the target temperature from the current temperature as temperature differences Δθ1, Δθ2, and warm air from the plurality of outlets 151, 152. Is obtained as a temperature difference Δθ1, Δθ2 by subtracting the current temperature from the target temperature. When the temperature difference at the first measurement point is greater than the positive threshold T1 and the temperature difference at the second measurement point is less than or equal to the positive threshold T1 and greater than 0, the determination unit 312 determines the temperature difference at the first measurement point according to the temperature difference at the first measurement point.
