摘要： PROBLEM TO BE SOLVED: To provide a highly reliable refrigerating cycle, by securing an oil return quantity to a compressor, even when a two-layer separating state of a refrigerant and refrigerating machine oil is caused in an accumulator.
SOLUTION: A bypass circuit 10 is arranged for connecting a delivery pipe and a suction pipe of a compressor 1 via a bypassing two-way valve 11. A control device 21 detects the evaporation temperature Teva by an evaporation temperature thermistor 22 arranged in an outdoor heat exchanger 2 in heating operation, after receiving a starting command of the compressor 1, and estimates the liquid refrigerant temperature Tacc in the accumulator 6 from the evaporation temperature Teva, and controls so as to open the bypassing two-way valve 11 for a prescribed time, only when the estimated liquid refrigerant temperature Tacc in the accumulator 6 is less than the low temperature side two-layer separating temperature. Thus, a large quantity of refrigerating machine oil delivered from the compressor 1 returns to the suction pipe of the compressor 1 by passing through the bypass circuit 10, to thereby reduce a quantity of refrigerating machine oil staying by separating into two layers by flowing in the accumulator 6.
