WIPO Patent Application WO/2018/034275
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a refrigeration cycle device having a simple configuration, and to provide a refrigeration cycle device in which excessive cooling and condensation in a power element can be prevented. An air conditioner to which this refrigeration cycle device is applied is provided with a cooling branched pipe (31) that allows some refrigerant between heat exchangers in a refrigerant circuit to bypass to an inlet side of a compressor, a cooler (32) that is in thermal contact with the cooling branched pipe (31) and uses some refrigerant to cool a power element (36) provided to an electric circuit that controls the operation of the compressor, and an expansion valve (33) provided only to a side of the cooling branched pipe (31) that is further downstream than the cooler (32).
