PROBLEM TO BE SOLVED: To provide a cooling system capable of accurately controlling a temperature of circulation liquid such as circulation water not only when a load of a heating source of an external connection destination is over a specified amount but also when a load of the heating source of the external connection destination is the specified amount or less.SOLUTION: A cooling system 50 includes a tank 16 for accommodating circulation liquid, and a refrigeration machine circuit 51 having an inverter-type refrigeration machine 1 in which a refrigerant passes, a condenser 3, an expansion valve 5, and an evaporator 7, and cooling the circulation liquid sent from a heating source through the evaporator 7. The refrigeration machine circuit 51 is provided with a bypass circuit 40 for adjusting a flow rate of the refrigerant flowing to an expansion valve 4 side by allowing the refrigerant to pass from a high-pressure refrigeration pipe 4 to a low-pressure refrigeration pipe 8, and a range RH1 of a first cooling capacity of the refrigeration machine circuit 51 in closing the bypass circuit 40, and a range RH2 of a second cooling capacity of the refrigeration machine circuit 51 in opening the bypass circuit, are determined.SELECTED DRAWING: Figure 1 |
