<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of ensuring the reliability of a compressor, by reducing the return of a liquid-phase refrigerant to the compressor as much as possible. <P>SOLUTION: The device includes a defrosting bypass circuit and a heat storage bypass circuit. The device is configured to open a first solenoid valve 30 after a predetermined time of operation for opening a second solenoid valve 42, so that a large amount of refrigerants collected in an indoor heat exchanger 16 and outdoor heat exchanger 14 during defrosting operation return to the compressor 6 at once, thereby preventing the reliability of the compressor 6 from being damaged. <P>COPYRIGHT: (C)2012,JPO&INPIT |
