Patent ID: 7254961

Claim:
A vapor compression 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 nozzle portion, which depressurizes and expands the refrigerant on a downstream side of the radiator; a refrigerant suction inlet, from which refrigerant is drawn by action of a flow of the high velocity refrigerant discharged from the nozzle portion; a mixing portion, through which the high velocity refrigerant discharged from the nozzle portion and the drawn refrigerant supplied from the suction inlet are mixed; and a pressurizing portion that converts a velocity energy of a flow of mixed refrigerant, which is mixed through the mixing portion, into a pressure energy; a first evaporator that is connected to a downstream side of the ejector; and a second evaporator that is connected to the suction inlet of the ejector, wherein the first evaporator and the second evaporator are constructed integrally to cool an air flow that is directed to a common subject cooling space.
