    Abstract: When a refrigerant flow-path switch performs switching to a first refrigerant flow path, an interior condenser heating air blown into an interior as a first temperature-adjustment subject and an auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger heats air blown to a battery as a second temperature-adjustment subject. In contrast, when the refrigerant flow-path switch performs switching to a second refrigerant flow path, an interior evaporator cooling air blown into the interior and the auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger cools the air blown to the battery. With this arrangement, one common auxiliary heat exchanger can cool or heat the air for the battery, thereby leading to reduction in size of an entire refrigeration cycle device.

    Abstract: In a refrigeration cycle device, a first evaporator for cooling a first cooling target and a second evaporator for cooling a second cooling target are arranged in parallel between a radiator and an accumulator, a first pressure reducer is arranged upstream of the first evaporator, and a mechanical expansion valve as a second pressure reducer is arranged upstream of the second evaporator. The refrigeration cycle device includes a refrigerant passage through which a portion of a refrigerant flowing out of the radiator flows while bypassing the second pressure reducer and the second evaporator, and is decompressed by a separate pressure reducer from the second pressure reducer, so as to return the refrigerant containing a liquid phase refrigerant to the accumulator, in a cooling operation mode for cooling only the second cooling target.

    Abstract: A heat pump cycle includes a refrigerant circuit and a coolant circuit. A first heat exchanger and a second heat exchanger are disposed between the refrigerant circuit and the coolant circuit. The first heat exchanger includes an exterior heat exchanger that functions as an evaporator in a heating operation, and a radiator for radiating heat of a coolant. The second heat exchanger transmits a heat of high-pressure refrigerant to the coolant in the heating operation. A temperature of refrigerant within the second heat exchanger is higher than a temperature of refrigerant within the first heat exchanger. The heat obtained from the second heat exchanger is supplied to the first heat exchanger through the coolant. Further, the heat obtained from the second heat exchanger is stored in the coolant. In defrosting operation, the coolant that has stored the heat therein is supplied to the first heat exchanger.

    Abstract: An evaporator evaporates a working fluid by heat from a battery. The evaporator includes at least one evaporation channel connected to the battery in a thermally conductive manner. The evaporator includes a supply channel connected to an upstream end of the evaporation channel, and supplies the working fluid in liquid phase from the supply channel to the evaporation channel. The evaporator includes an outflow channel connected with a downstream end of the evaporation channel, and discharges the working fluid. The outflow channel is disposed above the supply channel, and the supply channel is disposed at a position more insulated from the heat of the battery than the evaporation channel is.
