PURPOSE:To shorten a defrosting time of an outdoor heat exchanger and to improve comfortableness of a resident in a room by providing an accumulator between a low pressure side compressing part and a high pressure side compressing part in a refrigerating cycle using a compressor having the low and high pressure side compressing parts. CONSTITUTION:In a refrigerating cycle using a compressor 1 containing low and high pressure side compressing parts 1A, 1B to be driven by one motor 1D in a high pressure shell 1C, a discharge tube 2A of the part 1A is opened under a gas part of the upper part of an accumulator 5 through a solenoid valve 4. A liquid part of the lower part of the accumulator 5 is connected to one end of an outdoor heat exchanger 7 through a tube 11, a second throttle mechanism 6, and the other end of the exchanger 7 is connected to a suction tube 3A of the part 1A through a four-way valve 10. A discharge tube 2B of the part 1B is connected to one end of an indoor heat exchanger 8 through the valve 10, and the other end is opened to the liquid part of the lower part of the accumulator 5 through a tube 12 and a first throttle mechanism 9. |
