Abstract: A battery temperature control device includes a heating medium circuit that connects a battery heat exchanger, an outside air heat exchanger, a heating medium pump, and a flow rate regulating unit. The outside air heat exchanger is connected in parallel to the battery heat exchanger. The flow rate regulating unit adjusts a flow rate of the heating medium in a first path through which the heating medium flows via at least the outside air heat exchanger and a flow rate of the heating medium in a second path through which the heating medium flows by detouring around the outside air heat exchanger. The control unit controls the flow rate regulating unit to adjust a ratio between a flow rate of the heating medium in the first path and a flow rate of the heating medium in the second path.

Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.

Abstract: In a refrigeration cycle device, a heat supply unit is disposed in parallel with a heat utilization unit in a flow of a heat medium. A branching part branches the heat medium flowing out of a heat radiator into a flow flowing toward the heat utilization unit and a flow flowing toward the heat supply unit. A merging part is configured to cause the heat medium having passed through the heat utilization unit and the heat medium having passed through the heat supply unit to merge together and to flow toward the heat radiator. A switching unit switches an operation state between a first state in which the heat medium circulates between the heat radiator and the heat utilization unit, and a second state in which the heat medium circulates between the heat radiator, the heat utilization unit and the heat supply unit.
