Abstract

[Object] A chiller that is excellent in responsiveness to changes in the temperatures of coolants and that is excellent in the precision of temperature control is provided. [Solution] There are a first coolant circuit 3 that supplies a first coolant 7 in a first tank 40 to a first load 5, a second coolant circuit 4 that supplies a second coolant 8 in a second tank 60 to a second load 6, and a refrigeration circuit 2 that adjusts temperatures of the first and second coolants 7 and 8 to set temperatures by heat exchange between the first and second coolants 7 and 8 and refrigerants by using heat exchangers 21 and 22. The set temperature of the second coolant 8 is equal to the set temperature of the first coolant 7 or higher than the set temperature of the second coolant 8, and the set flow rate of the first coolant 7 is higher than the set flow rate of the second coolant 8, and the volume of the first tank 40 is larger than the volume of the second tank 60.
