REFRIGERANT CYCLE DEVICE

WIPO Patent Application WO/2019/230436

A1

The present invention comprises: a branching part (16) that divides a refrigerant that has been depressurized by a first depressurization part (13); a second depressurization part (17) that depressurizes refrigerant from one branch of the branching part (16); an ejector (14) that has a nozzle part (14a) that depressurizes refrigerant from the other branch of the branching part (16), a refrigerant suction port (14b) that suctions refrigerant by means of the suction effect of refrigerant that is sprayed from the nozzle part (14a), and a pressurization part (14d) that mixes and pressurizes refrigerant that has been sprayed from the nozzle part (14a) and refrigerant that has been suctioned through the refrigerant suction port; a suction-side heat exchanger (18) into which refrigerant that has been depressurized by the second depressurization part (17) flows and from which refrigerant is suctioned by the refrigerant suction port (14b); an outflow-side heat exchanger (15) into which refrigerant that has been pressurized by the pressurization part (14d) flows and out of which refrigerant flows toward a compressor (11); and a control part (30) that controls the throttle opening of the first depressurization part (13) such that refrigerant that has flowed out of a radiator (12) is supercooled to a prescribed degree.
