Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/022487
Kind Code:
A1
Abstract:
A refrigeration cycle device is provided with a pre-evaporator decompression unit (291, 59) which decompresses a refrigerant that has flowed out of an outdoor heat exchanger, and a via-evaporator path (54) through which the refrigerant that has flowed out of the outdoor heat exchanger flows to a suction port of a compressor via the pre-evaporator decompression unit and an evaporator. The refrigeration cycle device is provided with a bypass path (56) through which the refrigerant that has flowed out of the outdoor heat exchanger bypasses the pre-evaporator decompression unit and the evaporator and flows to the suction port of the compressor, a pre-outdoor-unit switching unit (28a), and a path switching unit (28b) which opens and closes the bypass path. The pre-outdoor-unit switching unit is switched between an open-side switching state in which the refrigerant flows from the compressor to the outdoor heat exchanger and a decompression-side switching state in which the refrigerant flows from the compressor to a heat radiator and the refrigerant decompressed more than in the open-side switching state after flowing out of the heat radiator flows to the outdoor heat exchanger. The pre-outdoor-unit switching unit and the path switching unit constitute an interlocking valve (28) in which the pre-outdoor-unit switching unit and the path switching unit work mechanically in an interlocking manner.
