REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/053746
Kind Code:
A1
Abstract:
The present invention suppresses generation of vibration and abnormal noise caused by discharge pulsation of a compressor. The present invention includes: a compressor (11) that sucks, compresses, and discharges a refrigerant; a radiator (12) that radiates heat of the refrigerant discharged from the compressor; a decompression unit (14a) that decompresses the refrigerant the heat of which has been radiated by the radiator; and a control unit (60) that controls an opening degree of the decompression unit to a normal opening degree. When determining that the refrigerant in a liquid phase is accumulated in the compressor in activation of the compressor, the control unit performs liquid ejection control of accelerating ejection of the refrigerant in the liquid phase accumulated in a range from the compressor to the decompression unit.
