The heat storage type air conditioner 14 includes a set of outdoor units 18, a plurality of indoor units 20, and a heat storage tank 22. That is, the heat storage type air conditioner 14 is an air conditioner in which the heat storage tank 22 is incorporated in a so-called multi air conditioner for buildings. The outdoor unit 18, the indoor unit 20, and the heat storage tank 22 are connected to a refrigerant pipe 24 through which refrigerant flows and wiring (not shown) for exchanging control signals and the like. The heat storage type air conditioner 14 generates heat by operating the outdoor unit 18 at night in addition to the normal cooling or heating operation, and the cooling or heating heat storage operation for storing the generated heat in the heat storage tank 22 and the daytime. In addition, the heat storage tank 22 supplies heat to the indoor unit 20 to perform cooling or heating of the living room using heat storage cooling or heating operation.

  The outdoor unit 18 is installed outdoors. One set of outdoor units 18 includes one or a plurality of outdoor units 18 according to the number of indoor units 20 and the air conditioning load that can be processed.

  The outdoor unit 18 constitutes a part of the refrigerant circuit, and includes a compressor, a heat exchanger, and a blower (all not shown). During the cooling operation, the low-pressure gaseous refrigerant sent from the indoor unit 20 is brought into a high-pressure state by the compressor. And the gaseous refrigerant made into the high voltage | pressure state is liquefied by passing a heat exchanger, and is sent to the indoor unit 20. FIG. In the heat exchanger, the outside air sent by the blower is warmed by the heat dissipation action when the gaseous refrigerant is liquefied. On the other hand, during the heating operation, the low-pressure liquid refrigerant sent from the indoor unit 20 is vaporized by passing through the heat exchanger. In the heat exchanger, the outside air sent by the blower is cooled by the endothermic action when the liquid refrigerant is vaporized. Then, the vaporized gas refrigerant is brought into a high pressure state by the compressor and sent to the indoor unit 20.

  The indoor unit 20 is installed in the living room 12. Specifically, the indoor unit 20 is installed on the ceiling surface of the living room 12, installed inside the ceiling, installed suspended from the ceiling, or installed on a wall surface. Note that the number of indoor units 20 corresponding to one living room 12 is not limited to one, and may be a plurality.

  The indoor unit 20 constitutes a part of the refrigerant circuit, and includes a heat exchanger, an expansion valve, and a blower (all not shown). During the cooling operation, the high-pressure liquid refrigerant sent from the outdoor unit 18 is brought to a low pressure state by the expansion valve. Then, the low-pressure liquid refrigerant is vaporized by passing through the heat exchanger, and is sent to the outdoor unit 18. In the heat exchanger, ambient air is cooled by an endothermic action when the liquid refrigerant is vaporized. The cooled air is sent into the living room 12 by a blower, whereby the cooling of the living room 12 is performed. On the other hand, during the heating operation, the high-pressure gaseous refrigerant sent from the outdoor unit 18 is liquefied by passing through the heat exchanger. The refrigerant that has been liquefied and turned into a liquid is brought to a low pressure state by the expansion valve and is sent to the outdoor unit 18. In the heat exchanger, the surrounding air is warmed by the heat dissipation action when the gaseous refrigerant is liquefied. The heated air is sent out into the living room 12 by a blower, whereby the heating of the living room 12 is performed.

  During the cooling heat storage operation, the high-pressure liquid refrigerant sent from the outdoor unit 18 is brought into a low-pressure state by the expansion valve. Then, the low-pressure liquid refrigerant is vaporized by passing through the heat exchanger, and is sent to the outdoor unit 18. In the heat exchanger, the water in the heat storage tank 22 is cooled to become ice and stored by the heat absorbing action when the liquid refrigerant is vaporized. And at the time of cooling operation using heat storage, heat storage is used to liquefy the refrigerant sent to the indoor unit 20.

  On the other hand, at the time of the heating and heat storage operation, the high-pressure gaseous refrigerant sent from the outdoor unit 18 is liquefied by passing through the heat exchanger. The refrigerant that has been liquefied to become liquid is brought to a low pressure state by the expansion valve and is sent to the outdoor unit 18. In the heat exchanger, the water in the heat storage tank 22 is warmed by the heat radiation action when the gaseous refrigerant is liquefied, and becomes warm water to be stored. And in heat storage utilization heating operation, in order to vaporize the refrigerant | coolant sent to the indoor unit 20, heat storage is utilized.

  In addition, the air conditioning system 10 includes a heat storage amount detection unit that detects a heat storage amount T that is a heat amount stored in the heat storage tank 22. The heat storage amount detection means in the present embodiment is a heat storage amount detection sensor 26 provided in the heat storage tank 22. The heat storage amount detection sensor 26 includes a water level sensor that detects the water level of the heat storage tank 22 and a temperature sensor that detects the water temperature of the heat storage tank 22. During cooling operation, the amount of ice can be grasped based on the water level detected by the water level sensor, so that the heat storage amount T can be detected. Further, during the heating operation, the heat storage amount T can be detected based on the water temperature detected by the temperature sensor. In the present embodiment, the case where the heat storage amount detection means is the heat storage amount detection sensor 26 provided inside the heat storage tank 22 has been described, but the present invention is not limited to this configuration. If the heat storage amount T of the heat storage tank 22 can be detected, as described in the prior art, the refrigerant inlet and outlet temperatures and the refrigerant flow rate with respect to the heat storage tank are detected, and the heat storage amount is based on these values. T can also be detected.

In addition, the centralized controller 16 can display an abnormality of the heat storage type air conditioner 14 and notify the abnormality of the abnormality.

  As shown in FIG. 1, the air conditioning system 10 of the present embodiment includes three systems of regenerative air conditioners 14. In order to distinguish these three systems, each system will be referred to as a, b, and c systems, respectively. Then, a, b, and c are appended to the numbers as the codes for devices corresponding to each system. In addition, in this embodiment, although the case where the air-conditioning system 10 had three heat storage type air conditioners 14 was demonstrated, this invention is not limited to this. In the air conditioning system 10, the regenerative air conditioner 14 can have a plurality of systems, for example, two systems or four systems.

  In the air conditioning system 10 of this embodiment, the indoor units 20 of different systems are provided in the same living room 12. Moreover, the air conditioning system 10 of this embodiment has the control part 30 which controls the indoor unit 20 provided in the above-mentioned same living room 12 based on the thermal storage amount T detected by the thermal storage amount detection means. And By such a special installation pattern of the indoor unit 20 and the operation of the control unit 30, it is possible to promote the leveling of the heat storage amount of each heat storage tank of a plurality of systems and to reduce the power cost. Hereinafter, the control unit 30 will be specifically described. The same living room 12 described above is a room in which cooling and heating are performed jointly by the indoor units 20 of different systems, and this is hereinafter referred to as a common living room 12k. And as a code | symbol of each indoor unit provided in this common room 12k, 20ak is attached | subjected about the thing of a system, 20bk about the thing of b system, and 20ck is attached to the thing of c system, respectively.

  The control unit 30 is built in the centralized controller 16. The present invention is not limited to this configuration, and the control unit 30 may be provided separately from the centralized controller 16. In this case, the control unit 30 is connected to the centralized controller 16 via wiring, or directly connected to the regenerative air conditioner 14 of each system via wiring.

  The control unit 30 controls the indoor units 20ak, 20bk, and 20ck so as to equalize the heat storage amount T of the heat storage tank 22 of each system. Thereby, the dispersion | variation in the heat storage amount T of each heat storage tank 22 at the time of heat storage utilization driving | operation can be suppressed.

  A specific control method of the control unit 30 for leveling the heat storage amount T will be described with reference to FIG. FIG. 2 is a diagram showing the heat storage amount T of each system. FIG. 2 shows the heat storage amount T of each heat storage tank 22 at a certain time during the heat storage utilization operation. In this figure, the heat storage amount T varies. That is, the heat storage amount T is in order of the heat storage amount Tb of the b system, the heat storage amount Tc of the c system, and the heat storage amount Ta of the a system from the largest.

  In this case, the control unit 30 uses the same a system indoor unit 20ak as the heat storage tank 22a having the heat storage amount Ta smaller than the heat storage amounts Tb and Tc, and the load processing capability of the indoor unit 20ak is the load processing capability of the indoor units 20bk and 20ck. Control to be smaller. The consumption rate of the heat storage amount Ta decreases due to a decrease in the load processing capacity of the indoor unit 20ak. In addition, due to a decrease in the load processing capacity of the indoor unit 20ak, the load processing capacity of the indoor units 20bk and 20ck is automatically increased to handle the air conditioning load of the shared living room 12k, and the consumption rate of the heat storage amounts Tb and Tc increases. To do.

  By such an operation of the control unit 30, the difference between the heat storage amounts Ta, Tb, and Tc is reduced, and the heat storage amount T can be leveled. When the heat storage amount T is leveled, it is possible to prevent a different operation for each system, that is, a state where a certain system is a normal operation by a compressor while another system is a heat storage operation. That is, the heat storage stored in the entire air conditioning system 10 can be efficiently consumed without remaining. Therefore, the effect of peak cut or peak shift is increased and the nighttime power can be used more effectively, so that the power cost can be reduced.

  A specific method in which the control unit 30 performs control so that the load processing capacity of the indoor unit 20ak is smaller than the load processing capacity of the indoor units 20bk and 20ck will be described. In order to reduce the load processing capacity of the indoor unit 20ak, the control unit 30 increases the set temperature of the indoor unit 20ak during the cooling operation, and decreases the set temperature of the indoor unit 20ak during the heating operation. Further, the control unit 30 reduces the air volume of the indoor unit 20ak. The control unit 30 can also perform a combination of these controls. Furthermore, the control unit 30 can also stop the indoor unit 20ak.

  In addition, in the state shown in FIG. 2, the control unit 30 uses the same b system indoor unit 20bk as the heat storage tank 22b having the heat storage amount Tb larger than the heat storage amounts Ta and Tc, and the load capacity of the indoor unit 20bk is the indoor unit. It can also be controlled so as to be larger than the load processing capacity of 20ak, 20ck. The consumption speed of the heat storage amount Tb increases due to an increase in the load processing capacity of the indoor unit 20bk. In addition, due to an increase in the load processing capacity of the indoor unit 20bk, the load processing capacity of the indoor units 20ak and 20ck is automatically reduced in order to handle the air conditioning load of the shared living room 12k, and the consumption rate of the heat storage amounts Tb and Tc is reduced. To do. Also by such operation | movement of the control part 30, the difference of each heat storage amount Ta, Tb, Tc shrinks, and the heat storage amount T can be leveled.

  A specific method in which the control unit 30 performs control so that the load processing capacity of the indoor unit 20bk is greater than the load processing capacity of the indoor units 20ak and 20ck will be described. In order to increase the load processing capacity of the indoor unit 20bk, the control unit 30 decreases the set temperature of the indoor unit 20bk during the cooling operation, and increases the set temperature of the indoor unit 20bk during the heating operation. In addition, the control unit 30 increases the air volume of the indoor unit 20bk. The control unit 30 can also perform a combination of these controls. Furthermore, the control unit 30 can also operate the indoor unit 20bk when the indoor unit 20bk is stopped.

  Next, the control operation of the air conditioning system 10 will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the control operation of the air conditioning system 10. This control operation starts at a certain point in the heat storage utilization operation.

  First, in step S101, each heat storage amount detection sensor 26 detects the heat storage amount T, respectively. In step S102, it is determined whether the heat storage amount T varies. When there is no variation in the heat storage amount T, the control operation ends. On the other hand, when there is variation in the heat storage amount T, the process proceeds to step S103, and the control unit 30 controls the small heat storage amount T so as to reduce the load processing capacity of the indoor unit 12k of the shared room 12k of the same system. In step S104, the control unit 30 controls the large heat storage amount T so as to increase the load processing capacity of the indoor unit 12k of the shared room 12k of the same system, and the control operation ends. In this control operation, the small heat storage amount T and the large heat storage amount T are determined based on the average value of the heat storage amounts T of all systems.

  Next, the control method of the control part 30 of another aspect is demonstrated using FIG. FIG. 4 is a diagram illustrating an example of the relationship between the heat storage amount Ta of the a system and the predetermined value t. In addition, the same code | symbol is attached | subjected about the same component as the said embodiment, and detailed description is abbreviate | omitted.

  In FIG. 4, a predetermined value t of the heat storage amount Ta in a time zone from the start to the end of the heat storage utilization operation, for example, a time zone from 9:00 to 18:00 is indicated by a broken line. Further, in FIG. 4, the actual heat storage amount Ta from the start of the heat storage use operation to a certain time point h1 is indicated by a solid line. The predetermined value t is stored in the control unit 30 in advance. The actual heat storage amount Ta is detected by the heat storage amount detection sensor 26 every predetermined time. In this figure, at a certain time point h1, the heat storage amount Th1 detected at this time becomes smaller than the predetermined value th1 at that time.

  In this case, the control unit 30 controls the indoor unit 20ak of the same system as the heat storage tank 22a having the heat storage amount Th1 so that the load processing capability of the indoor unit 20ak is smaller than the load processing capability of the indoor units 20bk and 20ck. . The consumption rate of the heat storage amount Ta decreases due to a decrease in the load processing capacity of the indoor unit 20ak.

  The operation of the control unit 30 can suppress the heat storage amount Ta from becoming smaller than the predetermined value t. And by performing the same control in other systems, it is possible to suppress that all the heat storage amount T is smaller than the predetermined value t in the time zone from the start to the end of the heat storage use operation, and as a result, each heat storage The difference in the amount T is reduced, and the heat storage amount T can be leveled. The predetermined value t can be set according to the air conditioning load, the outside air temperature, the season, etc. targeted by each system.

  In this embodiment, when the heat storage amount T is smaller than the predetermined value t, the case of controlling the load processing capacity of the target indoor unit 20 to be small has been described, but the present invention is not limited to this configuration. In order to suppress variation in each heat storage amount T, a second predetermined value t2 larger than the predetermined value t is set, and when the heat storage amount T is larger than the second predetermined value t2, load processing of the target indoor unit 20 It can also be controlled to increase the ability. By this control, it is possible to suppress that all the heat storage amount T becomes larger than the second predetermined value t2 in the time period from the start to the end of the heat storage use operation, and as a result, the difference between the heat storage amounts T is reduced, and the heat storage The amount T can be leveled. When these controls are combined, all the heat storage amounts T transition between the predetermined value t and the second predetermined value t2, and the difference between the heat storage amounts T can be effectively reduced.
