PROBLEM TO BE SOLVED: To provide a refrigeration cycle capable of keeping high system performance without impairing a refrigeration capacity even in a refrigeration cycle condition of the small expansion energy of a condensed refrigerant by a pressure reducing means. SOLUTION: This refrigeration cycle 1 constituted by successively connecting a compressor 10, a condenser 20, the pressure reducing means 30 and an evaporator 40, a gas-liquid separator 50 is mounted in the downstream of the pressure reducing means 30, a liquid refrigerant-side 50b of the gas-liquid separator 50 is connected with the inlet-side of the evaporator 40 through a liquid refrigerant circuit R2, a gas refrigerant-side 50a of the gas-liquid separator 50 is connected with the outlet side of the evaporator 40 through a gas refrigerant circuit R1, and a differential pressure means 32 is mounted to determine refrigerant pressure at the outlet side of the evaporator 40 to be lower than that at the inlet side.
