Abstract:
1. An ejector cycle comprising: a compressor for compressing refrigerant; a high-pressure heat exchanger for radiating heat from high-pressure refrigerant discharged from the compressor; a low-pressure heat exchanger for evaporating low-pressure refrigerant after being decompressed; an ejector including a nozzle for decompressing and expanding the high-pressure refrigerant from the high-pressure heat exchanger, and a pressure-increasing portion in which gas refrigerant evaporated in the low-pressure heat exchanger is sucked by a high-speed refrigerant flow jetted from the nozzle, and a pressure of refrigerant to be sucked to the compressor is increased by converting expansion energy to pressure energy; a gas-liquid separator which separates refrigerant flowing from the ejector into gas refrigerant and liquid refrigerant, the gas-liquid separator having a gas refrigerant outlet connected to a refrigerant suction side of the compressor, and a liquid refrigerant outlet connected to a refrigerant inlet side of the low-pressure heat exchanger; and an insulation member, provided on an outer surface of the ejector, for performing heat insulation.
