Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/198559
Kind Code:
A1
Abstract:
When dehumidifying and heating a space to be air conditioned, the flow of a refrigerant flowing out of an indoor radiator (13) is divided into portions. One of the divided portions of the refrigerant is reduced in pressure by an indoor expansion valve (17b) and is evaporated by an indoor evaporator (19). The other of the divided portions of the refrigerant is reduced in pressure by an outdoor expansion valve (17a) after being caused to flow into the high-pressure-refrigerant passage (18a) of an inside heat exchanger (18) and is evaporated by an outdoor heat exchanger (15). Further, a refrigerant circuit is selected, the refrigerant circuit combining the flow of a refrigerant which flows out of the indoor evaporator (19) and the flow of a refrigerant which flows out of the outdoor heat exchanger (15) and causing the joint flow to flow into the low-pressure-refrigerant passage (18b) of the inside heat exchanger (18). The above configuration prevents a refrigerant flowing into the indoor evaporator (19) from becoming a liquid phase refrigerant having an unnecessarily high degree of supercharging, thereby achieving appropriate dehumidification and heating.
