Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053334
Kind Code:
A1
Abstract:
This invention improves the cycle performance of a refrigeration cycle device that has an accumulator. This invention comprises: a compressor (31) for intaking, then compressing and discharging, a refrigerant; a heat radiator (15) for dissipating heat of the refrigerant discharged from the compressor (31); a decompression unit (32) for decompressing the refrigerant for which heat has been dissipated by the heat radiator (15); an evaporation unit (14) for causing the refrigerant that has been decompressed at the decompression unit (32) to evaporate; an accumulator for separating out the gas and liquid of the refrigerant evaporated by the evaporation unit (14) and draining out the gas-phase refrigerant; and a superheating unit (34) for superheating the refrigerant drained out from the accumulator by heat exchange with a heating medium of a higher temperature than the refrigerant drained out from the accumulator (33).
