PROBLEM TO BE SOLVED: To prevent shortage of heating capacity in defrosting an air conditioner. SOLUTION: The control device 20 controls at least any of a rotating speed of a compressor 1, pressure reduction of a pressure reducing means 4, a rotating speed of an indoor blower fan 12 and a rotating speed of an outdoor blower fan 13 on the basis of a temperature sensor 10 around a heat storage body 9 in storing heat. A means for determining melting of heat storage material is disposed in the control device, so that a part between an indoor heat exchanger and a four-way valve 2 and a part between an outdoor heat exchanger and the pressure reducing means are shorted when the means for determining melting of heat storage material determines the melting of the heat storage material, and the four-way valve is switched to allow a refrigerant of high temperature to flow into the outdoor heat exchanger when it is determined that the heat storage material is not melted in defrosting under air heating.
