PROBLEM TO BE SOLVED: To provide a refrigeration cycle which can improve a coefficient of performance.SOLUTION: A refrigeration cycle includes: a compressor 11 which compresses a refrigerant; a radiator 12 which radiates heat of the refrigerant compressed by the compressor 11; first and second decompressors 13, 23 which decompress the refrigerant after flowing out from the radiator 12; a first evaporator 14 which evaporates the refrigerant decompressed by the first decompressor 13; a first gas-liquid separator 15 which separates the refrigerant flowing out from the first evaporator 14 into gas and liquid; a second evaporator 24 which evaporates the refrigerant decompressed by the second decompressor 23 and of which an evaporation pressure is lower than that of the first evaporator 14; and an ejector 16 which has a first inflow port 16a connected to an outflow side of the gas-phase refrigerant of the first gas-liquid separator 15, a second inflow port 16b connected to the second evaporator 24, and an outflow port 16c connected to the compressor 11. The ejector 16 sucks and makes the refrigerant, which flows out from the second evaporator 24 by an inflow of the refrigerant from the first inflow port 16a, flow in from the second inflow port 16b. |
