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 interior of a nozzle in an ejector is formed with a swirling space in which a refrigerant swirls, and a refrigerant passage in which the refrigerant that has flowed from the swirling space is depressurized. The refrigerant passage includes a minimum passage area part most reduced in the refrigerant passage area, and a divergent part that gradually enlarges in the refrigerant passage area from the minimum passage area part toward a refrigerant ejection port. Plate members, which reduce a velocity component of the refrigerant flowing into the minimum passage area part in a swirling direction, are disposed within the refrigerant passage.

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: A mixing portion that is formed in an area from a refrigerant injection port of a nozzle portion to an inlet section of a diffuser portion in an internal space of a body portion of an ejector and that mixes an injection refrigerant injected from the refrigerant injection port and a suction refrigerant suctioned from a refrigerant suction port is provided. A distance from the refrigerant injection port to the inlet section in the mixing portion is determined such that a flow velocity of the refrigerant flowing into the inlet section of the diffuser portion becomes lower than or equal to a two-phase sound velocity. A shock wave that is generated at a time that a mixed refrigerant is shifted from a supersonic velocity state to a subsonic velocity state is generated in the mixing portion, so as to stabilize pressure increasing performance in the diffuser portion.

Abstract: A swirl space forming member that forms a swirl space in which a refrigerant flowing into a nozzle portion of an ejector swirls around an axis of the nozzle portion. In this way, even when the refrigerant flowing out of a first evaporator is a gas-phase refrigerant, pressure of the refrigerant on a swirling center axis side in the swirl space is reduced to be able to start condensation by swirling the refrigerant, and a gas-liquid two-phase refrigerant in which a condensation nucleus is generated can flow into the nozzle portion. Thus, occurrence of a condensation delay in the refrigerant in the nozzle portion can be restricted.

Abstract: A mixing portion that mixes an injection refrigerant and a suction refrigerant is formed in a range of an internal space of a heating-side body portion of a heating-side ejector from a refrigerant injection port of a heating-side nozzle portion to an inlet of a heating-side diffuser. Further, the mixing portion is formed in a shape that gradually decreases a refrigerant passage area toward a downstream side of a refrigerant flow, and a refrigerant passage area of the inlet of the heating-side diffuser is set smaller than that of the refrigerant injection port. Thus, the flow velocity of the mixed refrigerant is decelerated to a value lower than a two phase sound velocity within the mixing portion, thereby suppressing occurrence of shock wave in the heating-side diffuser and stabilizing the pressure increasing performance in the heating-side diffuser.
