PROBLEM TO BE SOLVED: To provide a heat storage type air conditioner having sufficient cold storage capability while quickly coping with the case that the amount of heat storage medium in a heat storage tank is less than a proper amount. SOLUTION: The heat storage type air conditioner capable of cold storage operation comprises a pressure sensor 33 provided on the suction side of a compressor 1 which entraps refrigerant passing through a heat storage heat exchanger 21, for detecting the suction pressure of the compressor, and an operation control means 50 for performing protecting operation of at least either stopping the compressor 1 or issuing an alarm when the pressure sensor 33 detects a preset pressure value which defines the heat storage medium in the heat storage tank to be in an insufficient condition in a preset target cold storage time during cold storage operation.
