Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/168158
Kind Code:
A1
Abstract:
A refrigeration cycle device (10) is provided with: a compressor (12) that compresses a refrigerant and discharges the refrigerant; a condenser (14) that condenses the refrigerant discharged from the compressor; an expansion valve (18) that expands the refrigerant flowing out from the condenser; and an evaporator (20) that evaporates the refrigerant flowing out from the expansion valve. Furthermore, the refrigeration cycle device is provided with: a bypass passage section that causes the refrigerant flowing out from the expansion valve to flow into a refrigerant inlet side of the compressor by bypassing the evaporator; and a solenoid valve that opens and closes the bypass passage section. Furthermore, the refrigeration cycle device is provided with a solenoid-valve control unit (500) that controls the solenoid valve such that the bypass passage section is opened when the temperature of the refrigerant discharged from the compressor exceeds a predetermined open reference temperature.
