PROBLEM TO BE SOLVED: To provide a refrigerating cycle and a refrigerating showcase capable of sucking and supplying a low pressure refrigerant upstream of a compressor 4 to a condenser 1 by negative pressure generated by driving flow, by forming the refrigerant compressed by the compressor 4 as the driving flow of an ejector 5, by arranging the ejector 5 between the compressor 4 and the condenser 1.SOLUTION: A refrigerating cycle includes a compressor 4 for compressing a refrigerant, a condenser 1 for condensing the refrigerant compressed by the compressor 4, an expansion valve 2 for expanding the refrigerant condensed by the condenser 1, an evaporator 3 for evaporating and supplying the refrigerant expended by the expansion valve 2 to the compressor 4, and an ejector 5 arranged between the compressor 4 and the condenser 1, and the ejector 5 forms the refrigerant compressed by the compressor 4 as a driving flow, and forms at least a part of the refrigerant of lower pressure than the refrigerant compressed by the compressor 4 as a suction flow, to be supplied to the condenser 1 by mixing the driving flow and the suction flow. |
