Claim 26:
27. A flow passage switching valve for a fluid circulation circuit that is for a fluid circulating, the flow passage switching valve comprising:
a body forming therein a fluid passage for the fluid flowing therethrough; and
a switcher configured to switch a passage configuration of the fluid passage; wherein
the body includes a first inlet for the fluid flowing into the body, a second inlet for the fluid flowing into the body, and outlets for the fluid having flowed into the body and flowing out of the body,
the outlets include a first outlet for the fluid having flowed in from the first inlet and flowing out of the body, a second outlet for the fluid having flowed into the body and flowing out of the body, and a third outlet for the fluid having flowed into the body and flowing out of the body,
the second inlet is an inlet for the fluid having flowed out of the body from the first outlet and flowing into the body again,
the switcher is configured such that the passage configuration is switchable to a state in which the fluid that has flowed in from the first inlet flows out of either one of two outlets: the first outlet and the second outlet,
the switcher is configured such that the passage configuration is switchable to a state in which the fluid that has flowed in from the second inlet flows out of either one of two outlets: the second outlet and the third outlet,
a length of a passage leading from the first inlet to the second outlet is smaller than a total length of a length of a passage leading from the first inlet to the first outlet and a length of a passage leading from the second inlet to the second outlet, and
the fluid circulation circuit is configured such that a first lowest temperature of the fluid flowing through the fluid passage leading from the first inlet to the second outlet is lower than a second lowest temperature of the fluid in a flow passage leading from the first outlet to the second inlet.
