ステム。1. A heat storage tank for storing a cooling medium that generates sherbet-like ice when the temperature becomes a predetermined temperature or less, a primary circulation line for circulating the cooling medium in the heat storage tank to a primary side of a heat exchanger. A secondary circulation line for circulating a cooling medium similar to the cooling medium to the secondary side of the heat exchanger and the condenser on the air conditioner side; and an inflow of the primary circulation line into the heat exchanger. A low-temperature side bypass line connecting a side line and an outflow side line from a heat exchanger of the secondary side circulation line and an on-off valve, and a heat exchanger of the primary side circulation line And a high-temperature bypass line in which an on-off valve is connected while connecting the inlet-side line to the heat exchanger of the secondary-side circulation line, and the primary-side circulation line. The temperature of the cooling medium flowing through the inflow side pipeline is measured, and the temperature of the cooling medium is higher than the predetermined temperature. Control means for opening on-off valves arranged in the low-temperature bypass line and the high-temperature side bypass line when the set temperature is exceeded; and a flow rate of the cooling medium flowing through the secondary-side circulation line, an inflow-side tube. A heat storage air-conditioning system, comprising: a cooling energy measuring means for measuring the temperatures of the passage and the outlet-side conduit, thereby integrating the amount of cooling of the cooling medium supplied from the primary-side circulation conduit.
