Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/215167
Kind Code:
A1
Abstract:
A refrigeration cycle device according to the present invention comprises: a compressor (11) that compresses and discharges a refrigerant; a heat dissipating section (16) that dissipates the heat of the refrigerant discharged from the compressor; a cooling decompression section (14b) that decompresses the refrigerant that has been subjected to heat dissipation at the heat dissipating section; an air-conditioning evaporation section (18) that exchanges heat between air and the refrigerant decompressed at the air-conditioning decompression section, evaporates the refrigerant, and cools the air; a cooling decompression section (14c) that decompresses the refrigerant that has been subjected to heat dissipation at the heat dissipating section; cooling sections (19, 52) that cool a battery by using heat from the battery to evaporate the refrigerant that has been decompressed at the cooling decompression section; and a gas-liquid separation section (21) that separates gas and liquid of refrigerant that has flowed out from the air-conditioning evaporation section and the cooling sections, returns the refrigerant in a gas phase to the compressor, and returns a refrigerating machine oil to the compressor. At least one of the air-conditioning decompression section and the cooling decompression section is controlled such that the refrigerant that has flowed out from the air-conditioning evaporation section has the degree of superheat.
