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: A regenerative heat exchanger includes a refrigerant pipe, a regenerator, and an air passage fin. The air passage fin is disposed in an air passage defined outside of the refrigerant pipe and the regenerator, and is thermally connected with the regenerator directly or through the refrigerant pipe. At least one of the regenerator and the air passage fin is configured such that a thermal resistance between a part of a regenerative material located on an upstream side and air flowing through the air passage becomes larger than a thermal resistance between a part of the regenerative material located on a downstream side and air flowing through the air passage.

Abstract: A first header tank and a second header tank of a cold-storage heat exchanger are located away from each other. Refrigerant tubes include refrigerant passages through which the first header tank and the second header tank communicate with each other. The refrigerant tubes are spaced away from each other. Cold energy containers storing cold energy storage members are provided to close air passage portions defined between the refrigerant pipes. A region including the air passage portions are separated into a first region including a center part of the region and a second region that is remaining part of the region. A proportion of the cold energy containers in the second region is larger than that in the first region.

Abstract: A vehicle air conditioner includes a refrigeration cycle unit, a heater core, a cool air bypass passage, an air volume ratio regulator, and an auxiliary heat exchanger. The heater core is disposed in a heating passage located downstream of an evaporator with respect to an airflow. The auxiliary heat exchanger is provided in the refrigeration cycle unit. The evaporator includes a cold energy storage configured to store cold energy. The cold energy storage stores cold energy when the compressor is in operation, and dissipate cold energy while the compressor stops. The auxiliary heat exchanger is located downstream of the evaporator and upstream of the heater core with respect to the airflow. The auxiliary heat exchanger is configured to change enthalpy of refrigerant by heat exchange between the refrigerant and air having been cooled by the evaporator and to be heated by the heater core.

Abstract: A refrigeration cycle device includes an interior condenser that exchanges heat between a high-pressure refrigerant and ventilation air to heat the ventilation air, an exterior heat exchanger that exchanges heat between outside air and the refrigerant downstream of the interior condenser, an interior evaporator that exchanges heat between a low-pressure refrigerant downstream of the exterior heat exchanger and the ventilation air before passing through the interior condenser, and an internal heat exchanger that exchanges heat between the refrigerant flowing out of the exterior heat exchanger and the refrigerant flowing out of the interior evaporator. The refrigeration cycle device further includes a gas-liquid separator that separates the refrigerant at a downstream side of the interior condenser into gas and liquid phase refrigerants. In a dehumidification heating mode of evaporating the refrigerant at the exterior heat exchanger, the liquid-phase refrigerant separated by the gas-liquid separator flows into the exterior heat exchanger.
