Abstract: A heat medium circuit including a first path and a heat medium circuit including a second path are formed independently from each other by operating a first switching valve and a second switching valve in conjunction with each other to make each of multiple flow passages of a first flow passage group communicate with either the first path or the second path. A heat medium circuit in which the first path and the second path are connected to each other in series is formed by operating the first switching valve and the second switching valve in conjunction with each other to make each of the multiple flow passages of the first flow passage group communicate with both the first path and the second path.

Abstract: A radiator cap is connected to a circulating circuit at a connecting point located upstream of a water pump in a flow direction of coolant and that regulates a pressure in the circulating circuit to be within a predetermined pressure range that is higher than or equal to an atmospheric pressure at the connecting point. A rotary valve is disposed in the circulating circuit at upstream of the connecting point of the radiator cap in the flow direction of coolant. Accordingly, a cavitation is restricted from occurring, and the water pump can perform enough efficiency. A communication passage that has an upstream end and a downstream end connected to the circulating circuit may be disposed instead of the radiator cap. In this case, a pressure regulating valve is disposed in the communication passage.

Abstract: An air conditioner includes: a heat-medium air heat exchanger that exchanges sensible heat between a heat medium having a temperature adjusted by the heat-medium temperature adjuster and ventilation air blowing to a space to be air-conditioned; a heat transfer portion having a flow path through which the heat medium circulates to transfer heat with the heat medium having the temperature adjusted by the heat-medium temperature adjuster; a large-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat transfer portion; and a small-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat-medium air heat exchanger. The small-inner-diameter pipe has small inner diameters ϕH and ϕC, compared to the large-inner-diameter pipe.

Abstract: A flow passage switching unit includes side-by-side arranged rotary valve parts. The valve part includes a casing, side walls, a peripheral wall, first fluid ports, a second fluid port, a rotary shaft, and a valving element. A flow passage, through which the first fluid ports and the second fluid port selectively communicate, is formed by rotation of the valving element. The unit includes a driving mechanism driving each valving element by its corresponding predetermined rotation angle. The driving mechanism includes one driving source, and a motive power transmission member transmitting rotation motive power of the driving source respectively to the valve parts. Motive power of the driving source is transmitted to each rotary shaft of the valve parts to drive each valving element to a position, which position of the valving element relative to the first and second fluid ports is different from one another among the valve parts.

Abstract: First circulation portions switch a flow of a heat transfer medium such that one of the heat transfer media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat transfer medium such that the heat transfer media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat transfer medium so as to form a first circulation circuit for allowing the heat transfer medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat transfer medium to circulate among the first flow path group, the second flow path group, and a second pump.
