Abstract
[Object] To provide a chiller reduced in size, cost, and energy use.[Solution] A chiller C1 includes a tank 1, a pump 2, a plurality of coolant circuits 3 and 4 configured to cool a plurality of respective loads, and a refrigeration circuit 5. The plurality of coolant circuits 3 and 4 and the refrigeration circuit 5 are connected to each other via respective heat exchangers 6 and 7 capable of individually controlling cooling performance. The first heat exchanger 6 connecting the first coolant circuit 3 and the refrigeration circuit 5 is configured to control a temperature of a coolant that returns from a first load W1 and a second load W2 to the tank 1. The second heat exchanger 7 connecting the second coolant circuit 4 and the refrigeration circuit 5 is configured to control a temperature of the coolant that is supplied from the tank 1 to the second load W2.
