Abstract: A four-way valve includes a body and a valve component. The body includes a valve chamber and first to fourth communication channels which communicate with the valve chamber at positions arranged in sequence in a predefined rotational direction and cause the valve chamber to communicate with an outside. The valve component is rotatable in the predefined rotational direction and switches the four-way valve to be in at least one of: a first state in which the first and second communication channels communicate with the first region and the third and fourth communication channels communicate with the third region; and a second state in which the second communication channel communicates with the first region, the third communication channel communicates with the second region, and the first and fourth communication channels communicate with the third region.

Abstract: A temperature control system is used for controlling a temperature of a control target. The system includes: a first circulation circuit through which a first heat transfer medium circulates; a second circulation circuit that is independent of the first circulation circuit and through which a second heat transfer medium circulates; and a third circulation circuit that is independent of the first circulation circuit and the second circulation circuit and through which a third heat transfer medium circulates. The third heat transfer medium has a usable temperature range wider than usable temperature ranges of the first heat transfer medium and the second heat transfer medium.
