摘要： An air conditioning apparatus (1) comprises a refrigerant circuit (10) having a compressor (21), an outdoor heat exchanger (23), indoor heat exchangers (42a, 42b), and a heat storage heat exchanger (28) for performing heat exchange between a refrigerant and a heat storage medium, the air conditioning apparatus being capable of performing a heat storage operation and simultaneously performing a heat-storage-utilizing operation and an air-warming operation during a defrosting operation. During the defrosting operation accompanying the heat-storage-utilizing operation in the air conditioning apparatus (1), the defrosting capability of the outdoor heat exchanger (23) is altered based on the outdoor temperature of the external space where the outdoor heat exchanger (23) is located, and/or either an outdoor heat exchange outlet temperature, which is the temperature of the refrigerant in an outlet of the outdoor heat exchanger (23) at the end of the previous defrosting operation, or the time required for the previous defrosting operation.

摘要： A control unit (1a) of a heat pump system (1) during air-warming operation controls usage-side expansion valves (82a, 82b) so that a degree of subcooling (SCu) of an outlet refrigerant is equal to a target degree of subcooling (SCus) of the outlet refrigerant, and controls a heat-source-side expansion valve (28) so that a degree of superheat (SHh) of the outlet refrigerant is equal to a target degree of superheat (SHhs) of the outlet refrigerant. Furthermore, the control unit (1a) performs refrigerant recovery control for changing the target degree of superheat (SHhs) of the outlet refrigerant so that the refrigerant in the outlet of the heat-source-side heat exchanger is wet when the usage-side expansion valves (82a, 82b) are opened to be greater than an opening degree (OPcs) for the start of refrigerant recovery, and cancelling the change in the target degree of superheat (SHhs) of the outlet refrigerant when the usage-side expansion valves (82a, 82b) are closed to be smaller than an opening degree (OPce) for the end of refrigerant recovery.
