Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/217142
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device comprising a compressor (11), a first branch section (12), a heat dissipator (13), a second branch section (16), a first pressure reduction section (17, 40), a first evaporator (18, 52), a second pressure reduction section (24, 69), a second evaporator (25, 60), an ejector (22), and a confluence section (20). The heat dissipator dissipates the heat of one refrigerant having been discharged from the compressor and diverted by the first branch section. The first pressure reduction section reduces the pressure of one refrigerant, the heat of which has been dissipated at the heat dissipation section, and which has been diverted at the second branch section. The second pressure reduction section reduces the pressure of the other refrigerant having been diverted at the second branch section. The ejector has: a nozzle section (221) for reducing the pressure of the other refrigerant which has been diverted at the first branch section and injecting the other refrigerant as an injection refrigerant; a refrigerant suction opening (22b) which, by means of the suction effect of the injection refrigerant, sucks in, as a suction refrigerant, a refrigerant vaporized at the second evaporator; and a pressure increasing section (222b) for mixing the injection refrigerant and the suction refrigerant to increase the pressure of the mixture.
