摘要：PROBLEM TO BE SOLVED: To raise efficiency of a refrigeration cycle using a non-azeotropic mixture refrigerant. SOLUTION: A discharge side and a suction side of a compressor 1 are switched and connected to one sides of an outdoor heat exchanger 3 and an indoor heat exchanger 6 through a four-way valve 2. A refrigerant separator 4 for separating the non-azeotropic mixture refrigerant and a throttling means 5 provided in the downstream side of the separator are provided between the other sides of the outdoor heat exchanger 3 and the indoor heat exchanger 6. A rectifying circuit comprising a plurality of check valves 7 is provided so as to make the flow direction of the refrigerant flowing to the separator 4 constant regardless switching of the four-way valve 2. A bypass circuit 9 having a second throttling means 8 between a bottom outlet of the separator 4 and the suction side of the compressor 1 is provided. In a refrigerating cycle constituted as described above, a heat exchanger 10 is provided for heat- exchanging by passing the refrigerant separated by the separator 4 and flowing to the first throttling means and the refrigerant decompressed in the second throttling means 8 and returned to the compressor 1.
