PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of improving reliability of a compressor by minimizing return of a liquid-phase refrigerant to the compressor. SOLUTION: This refrigerating cycle device configured by connecting the compressor 6, an indoor heat exchanger 16, an expansion valve 12 and an outdoor heat exchanger 14 to each other by refrigerant piping, is provided with a heat storage device having a heat storage material 36 disposed in a state of surrounding the compressor 6 and storing heat generated by the compressor 6, and a heat storage heat exchanger 34 exchanging heat between the heat stored in the heat storage material 36 and a refrigerant. Further it includes piping 28 for guiding a part of the refrigerant discharged from the compressor 6 to the outdoor heat exchanger 14, and piping 38 for guiding the refrigerant from the indoor heat exchanger 16 to the heat storage heat exchanger 34 in a defrosting operation, and the refrigerant from the heat storage heat exchanger 34 is joined with the refrigerant from the outdoor heat exchanger 14.
