PROBLEM TO BE SOLVED: To provide a refrigeration system which, even in the case where a load of a refrigerator is small such as in winter, secures a heat source necessary for a hot water supply operation of a supercooling water heater unit and sufficiently secures a hot water amount in a hot water storage tank, and which can improve reliability of equipment by suppressing start and stop frequency of the refrigerator and the supercooling water heater unit.SOLUTION: A refrigeration system is configured by including: a refrigerator 10 including a supercooling heat exchanger 13 for cooling a show case 2; and a supercooling water heater unit 20 including the supercooling heat exchanger 13 and a gas cooler 22, and for performing hot water supply by the gas cooler 22. It also includes a control device 40 which controls so as to perform a defrosting operation of the show case 2 in the case where a hot water temperature in a hot water storage tank 31 of the supercooling water heater unit 20 is equal to or less than a certain temperature.SELECTED DRAWING: Figure 1 |
