PROBLEM TO BE SOLVED: To provide a vapor compression type refrigerating cycle comprising an accumulator capable of preventing flowing of a liquid-phase refrigerant into a vapor outflow tube in low load, and reducing cycle variability in low load. SOLUTION: In this vapor compression type refrigerating cycle comprising a compressor, a radiator, an internal heat exchanger, a pressure reducing machine, an evaporator, and the accumulator for separating the refrigerant flowing out from the evaporator and allowing the separated gas-phase refrigerant to flow out to a suction side of the compressor, a part disposed inside of the accumulator, of the vapor outflow pipe 22 of the accumulator 6 is at least partially constituted as a multitubular structure, and a plurality of pores 32 are formed on inner and outer tubular walls of the multitubular structural part.
