Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065039
Kind Code:
A1
Abstract:
A refrigeration cycle device (10) configured so as to have a compressor (11), a high-temperature-side water-refrigerant heat exchanger (12), a branch unit (14a), an expansion valve (15a) for cooling, an expansion valve (15b) for heat absorption, an indoor evaporator (16), and an outdoor evaporator (18). The expansion valve (15a) for cooling and the indoor evaporator (16) are connected to one refrigerant outlet of the branch unit (14a), and the expansion valve (15b) for heat absorption and the outdoor evaporator (18) are connected to the other refrigerant outlet of the branch unit. In a cooling mode the device is switched to a refrigerant circuit in which refrigerant that has been decompressed in the expansion valve (15a) for cooling is made to exchange heat with blown air in the indoor evaporator (16), and in a heating mode the device is switched to a refrigerant circuit in which refrigerant that has been decompressed in the expansion valve (15b) for heat absorption is made to exchange heat in the outdoor evaporator (18), thereby absorbing heat from outside air and heating the blown air.
