<p>In a defrosting operation, a refrigerant discharged from a compressor 6 is introduced to an outdoor heat exchanger 14 and to a heat storage heat exchanger 34 via an indoor heat exchanger 16, and a refrigerant having passed through the outdoor heat exchanger 14 and another refrigerant heat-exchanged with a heat storage material 36 in the heat storage heat exchanger 34 join and are subsequently introduced to a suction side of the compressor 6. When an outdoor temperature detected by an outdoor temperature sensor 44 is greater than or equal to a predetermined value, an outdoor fan 48 is operated.</p> |
