PROBLEM TO BE SOLVED: To provide a freezing-refrigerating system having a new configuration interconnecting both cycles via a heat storage tank to eliminate the "synchronism of cooling actions of respective refrigerating cycles on low and high temperature sides" and "necessity of a heat exchanger for directly interconnecting the respective refrigerating cycles" in the conventional two refrigerating cycles. SOLUTION: This heat storage type refrigerating system includes: a first refrigerating cycle including a high-temperature side condenser 1 and a high-temperature side evaporator 3; a second refrigerating cycle including a low-temperature side condenser 7 and a low-temperature side evaporator 11; the one heat storage tank 5 storing the evaporator 3 of the first refrigerating cycle and the condenser 7 of the second refrigerating cycle; and a heat storage medium 6 stored within the heat storage tank 5. The heat storage medium 6 within the heat storage tank 5 is cooled by the evaporator 3 of the first refrigerating cycle to store cold, and the condenser 7 of the second refrigerating cycle is cooled by the cold stored in the heat storage medium 6 within the heat storage tank 5 to condense a refrigerant in the second refrigerant cycle.
