Abstract:
1. An ejector cycle comprising: a compressor that draws and compresses refrigerant; a radiator that radiates heat from the compressed high pressure refrigerant discharged from the compressor; an ejector that includes: a first evaporator that evaporates the refrigerant, which is outputted from the ejector, to achieve a refrigeration capacity, wherein a refrigerant outlet of the first evaporator is connected to a suction inlet of the compressor; a first branched passage that branches a flow of the refrigerant at a corresponding branching point located between the radiator and the ejector, wherein the first branched passage conducts the branched flow of the refrigerant to the gas phase refrigerant suction inlet of the ejector; a first metering means that depressurizes the refrigerant on a downstream side of the radiator; and a second evaporator that is arranged in the first branched passage, wherein the second evaporator evaporates the refrigerant to achieve a refrigeration capacity.
