Title:
Refrigerating cycle device
Document Type and Number:
Japanese Patent JP6277888
Kind Code:
B2
Abstract:
When performing dehumidification heating of a space to be air-conditioned, a refrigeration cycle device is switched to a refrigerant circuit in which a flow of a refrigerant flowing out of an interior radiator is branched, and one of the branched refrigerants is decompressed by an interior expansion valve to evaporate in an interior evaporator, while the other of the branched refrigerants flows into a high-pressure side refrigerant passage of an internal heat exchanger and is then decompressed by an exterior expansion valve to evaporate in an exterior heat exchanger. Further, in the refrigerant circuit, a flow of the refrigerant flowing out of the interior evaporator and a flow of the refrigerant flowing out of the exterior heat exchanger are merged into a low-pressure side refrigerant passage of the internal heat exchanger. Thus, the refrigerant flowing into the interior evaporator is prevented from becoming a liquid-phase refrigerant having an unnecessarily high degree of supercooling, thereby achieving appropriate dehumidification heating.
