<P>PROBLEM TO BE SOLVED: To obtain a refrigerating cycle device capable of suppressing decomposition of tetrafluoropropene. <P>SOLUTION: The refrigerating cycle device is provided with a refrigerant circuit in which a compressor 1, an outdoor heat exchanger 5, a throttle device 4, an indoor heat exchanger 3 and an accumulator 6 are interconnected annularly. As a refrigerant, a nonazeotropic refrigerant mixture including tetrafluoropropene and an HFC refrigerant having a boiling point lower than that of the tetrafluoropropene is used, and as refrigerating machine oil, alkyl benzene oil is used. <P>COPYRIGHT: (C)2010,JPO&INPIT |
