Abstract: A heater core for performing heat exchange between a coolant and ventilation air to be blown to the interior of a vehicle so as to heat the ventilation air is disposed in a water circulation circuit for circulating a coolant in an engine EG for outputting driving force necessary to move the vehicle. When the temperature of the coolant discharged from the engine EG is low, a heat transport refrigeration cycle device, serving as a heat transport unit for absorbing heat from a downstream coolant at a position downstream more than the heater core and dissipating the heat absorbed from the downstream coolant to an upstream coolant at a position upstream more than the heater core, is operated to increase the temperature of the coolant introduced into the heater core until the temperature of the coolant reaches the temperature necessary to heat the interior of the vehicle, without operation of the engine EG.

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: A fuel cell is used for generating driving energy for a vehicle. The reserve-tank inlet valve is located between a suction side of the coolant pump and a position in the coolant circuit at which a pressure of the coolant controlled by the reserve-tank inlet valve is an intermediate value between a discharge pressure of the coolant pump and a suction pressure of the coolant pump during an operation of the coolant pump. Even if the fuel cell is stopped generating electric power, the coolant pump is made continue operating even when the vehicle is traveling in a case that a coolant temperature exceeds a predetermined temperature. The coolant pump is made stop rotating after the coolant temperature becomes lower than or equal to the predetermined temperature. Accordingly, an occurrence of cavitation in the coolant pump is restricted at the time of restarting the fuel cell just after the fuel cell is stopped in a vehicle that is driven by the driving energy generated by the fuel cell working as a driving-energy generator.
