Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2021173426
Kind Code:
A
Abstract:
To inhibit dry out in a battery cooling section.SOLUTION: A refrigeration cycle device includes: a compressor 11 compressing and discharging a refrigerant; a heat radiation section 16 radiating heat from the refrigerant discharged from the compressor; an air-conditioning decompression section 14b decompressing the refrigerant of which heat has been radiated by the heat radiation section; an air-conditioning evaporation section 18 evaporating the refrigerant by exchanging heat between the refrigerant decompressed by the air-conditioning decompression section with air and cooling air; a battery decompression section 14c decompressing the refrigerant of which heat has been radiated by the heat radiation section; battery cooling sections 19, 52 cooling a battery by evaporating the refrigerant decompressed by the battery decompression section by using heat of the battery; and a gas liquid separation section 21 performing gas liquid separation of the refrigerant caused to flow out from the air-conditioning evaporation section and the battery cooling section to return a gas-phase refrigerant to the compressor and returning refrigeration machine oil to the compressor. At least one of the air-conditioning decompression section and the battery decompression section is controlled so that the refrigerant caused to flow out from the air-conditioning evaporation section has a degree of superheat.SELECTED DRAWING: Figure 6
