PROBLEM TO BE SOLVED: To provide an air conditioner capable of shortening a defrosting time while improving comfort in indoor heating by a defrosting/heating operation.SOLUTION: An air conditioner includes a refrigeration cycle constituted by connecting a compressor, a four-way valve, an indoor heat exchanger, a pressure reducer and an outdoor heat exchanger by a refrigerant pipe, and capable of heating indoors while partially defrosting the outdoor heat exchanger. The refrigeration cycle has a heat storage type heat exchanger connected with the refrigerant pipe positioned between the compressor and the four-way valve in parallel, connected with the four-way valve at its inlet, and connected with a suction side of the compressor at its outlet. The heat storage-type heat exchanger has a heat storage material, a heat storage type heat exchange pipe having a spiral pipe spirally formed from the inlet to a bottom portion and a straight pipe linearly formed to the outlet, and a heater positioned inside of the spiral pipe. |
