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.
