PROBLEM TO BE SOLVED: To provide a thermal storage type air conditioner capable of being controlled so that a refrigerant does not have a two-phase state at an inlet side of a compressor even when the refrigerant is supercooled and liquefied in a heat storage utilization-cooling operation. SOLUTION: A refrigerant circuit 110 of this thermal storage type air conditioner has a superheating degree deviation calculating means and a throttle opening adjusting means, and a refrigerant temperature detected by a thermal storage tank refrigerant temperature detecting means 45 at an outlet side of a regenerative heat exchanger 10, a refrigerant temperature detected by a gas pipe-side refrigerant temperature detecting means 46 at an inlet side of an indoor-side heat exchanger 30, a refrigerant temperature detected by a liquid pipe-side refrigerant temperature detecting means 47 at an outlet side of the indoor-side heat exchanger 30, a refrigerant temperature detected by a compressor discharging-refrigerant temperature detecting means 41 at an outside side of the compressor 1, and a refrigerant pressure detected by a compressor discharging-refrigerant pressure detecting means 51 are respectively input to the superheating degree deviation calculating means, so that a suction superheating degree of the refrigerant in the indoor-side heat exchanger 30, and its deviation from a target value are calculated.
