Abstract

A temperature control system includes: first and second refrigerator units; a first fluid flow apparatus that allows a first fluid to flow therethrough and that is cooled by the first refrigerator unit; a second fluid flow apparatus that allows a second fluid to flow therethrough and that is cooled by the second refrigerator unit; and a valve unit that is configured to allow the first fluid or the second fluid to selectively flow out therefrom. The first refrigerator unit has, in a medium-temperature-side refrigerator, a medium-temperature-side first expansion valve and a medium-temperature-side second expansion valve. A medium-temperature-side second evaporator corresponding to the medium-temperature-side second expansion valve and a low-temperature-side condenser of a low-temperature-side refrigerator constitute a cascade condenser. The first fluid is cooled by a medium-temperature-side first evaporator corresponding to the medium-temperature-side first expansion valve, and is then cooled by a low-temperature-side evaporator of the low-temperature-side refrigerator.
