Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/166270
Kind Code:
A1
Abstract:
This refrigeration cycle device comprises an air-cooling decompression unit (13) that decompresses a refrigerant subjected to heat radiation in a radiator (12), a first evaporator (14) that causes the refrigerant decompressed by the air-cooling decompression unit to evaporate by exchanging heat with air, an inlet-side decompression unit (15) that is arranged in parallel to the air-cooling decompression unit in the flow of the refrigerant and that decompresses the refrigerant subjected to heat radiation in the radiator, a second evaporator (16) that causes the refrigerant decompressed by the inlet-side decompression unit to evaporate by absorbing heat from a battery (2), an outlet-side decompression unit (18) that decompresses the refrigerant evaporated by the second evaporator, and a control unit (50) that controls the degree of opening of the inlet-side decompression unit and the outlet-side decompression unit, wherein the control unit performs restriction control for controlling the degree of opening of the inlet-side decompression unit to either a battery cooling opening degree which is the degree of opening for bringing the battery cooling capability of the second evaporator to a target battery cooling capability, or an air cooling opening degree which is the degree of opening for bringing the air cooling capability of the first evaporator to a target air cooling capability, whichever is smaller.
