PROBLEM TO BE SOLVED: To provide a cooling system suitable for saving electric power in consideration of environmental problems such as global warming. SOLUTION: The cooling system is provided with a plurality of heat exchangers provided to correspond to a plurality of cooling targets generating heat, respectively, receiving inflow of a refrigerant, making the refrigerant absorb heat of the corresponding cooling targets, and making the refrigerant flow out; a heat generation quantity detecting means for detecting the heat generation quantity of each of the plurality of cooling targets; a plurality of cooling machines for cooling the refrigerant to temperatures different from each other; a circulation path for circulating the refrigerant between each of the plurality of cooling machines and each of the plurality of heat exchangers; change-over valves provided to correspond to the plurality of heat exchangers, respectively and selectively switching the connection destination of the circulation path of the refrigerant passing through the corresponding heat exchangers to any of the plurality of cooling machines; and a circulation control means for making the change-over valves switch the circulation path based on the heat generation quantity of each of the plurality of cooling targets detected by the heat generation quantity detecting means, so that the refrigerant is circulated between the heat exchanger for cooling the cooling target with the smaller heat generation quantity and the cooling machine for cooling the refrigerant to a relatively higher temperature out of the plurality of cooling machines.
