<P>PROBLEM TO BE SOLVED: To provide a refrigeration cycle device that can further improve the defrost performance during a defrosting operation while minimizing the return of a liquid phase refrigerant to a compressor so that the reliability of the compressor is ensured. <P>SOLUTION: The refrigeration cycle device includes a defrosting bypass circuit and a heat storage bypass circuit. The refrigeration cycle device is configured to open a second electromagnetic valve 42 during a defrosting operation in a predetermined period after the opening of a first electromagnetic valve 30. This configuration can prevent a large amount of refrigerant accumulated in an indoor heat exchanger and an outdoor heat exchanger during the defrosting operation from returning to the compressor at once, and the reliability of the compressor from losing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
