REFRIGERATION CYCLE DEVICE

摘要

A refrigeration cycle device having a compressor (6), an indoor heat exchanger (16), an expansion valve (12), and an outdoor heat exchanger (14), which are connected through refrigerant piping, is provided with a heat storage device for storing heat generated by the compressor (6). The refrigeration cycle device is also provided with a controller which switches the operation of the device from first heating operation to second heating operation, the first heating operation being operation which, when the temperature of a heat storage material (36) contained in a heat storage tank (32) is lower than or equal to a predetermined temperature, causes the refrigerant discharged from the compressor (6) to pass through the indoor heat exchanger (16), the expansion valve (12), and the outdoor heat exchanger (14), the second heating operation being operation which, when the temperature of the heat storage material (36) exceeds the predetermined temperature, causes the refrigerant discharged from the compressor (6) to pass through the indoor heat exchanger (16) and a heat storage heat exchanger (34).
