Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163935
Kind Code:
A1
Abstract:
A refrigeration cycle device comprises: a variable displacement compressor (1) that has a discharge capacity varying unit to change the refrigerant discharge capacity; a control unit (100) that outputs a capacity control signal for changing the refrigerant discharge capacity to the variable displacement compressor; a heat exchanger (2) that condenses or cools the refrigerant discharged from the variable displacement compressor; a pressure reducing unit (3) that reduces the pressure and expands the refrigerant flowing from the heat exchanger; an evaporator (4) that evaporates the refrigerant for which the pressure has been reduced and that has been expanded by the pressure reducing unit; and a high load determination unit (S100) that determines whether the compressor is in a high-load operation state on the basis of the capacity control signal.
