Title:
REFRIGERANT CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/230435
Kind Code:
A1
Abstract:
The present invention comprises: a compressor (11) that sucks in and discharges a refrigerant; a radiator (12) that releases heat from refrigerant that has been discharged from the compressor (11); an ejector (14) that has a nozzle part (14a) that depressurizes refrigerant that has flowed out of the radiator (12), 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; and layered heat exchangers (15, 18) into which refrigerant that has been pressurized by the pressurization part (14d) flows and from which refrigerant is suctioned by the refrigerant suction port. The layered heat exchangers are formed by layering and joining a plurality of plate-shaped members (151). Refrigerant flow channels in which refrigerant flows and liquid flow channels in which a liquid flows are formed between the plurality of plate-shaped members (151).
