  • Publication number: 20150380785
    Abstract: In a temperature regulation device, when a control device determines that warming-up operation of an assembled battery is necessary, and when a humidity of an air detected by a temperature/humidity sensor is equal to or lower than a predetermined humidity, a conditioned air that has been drawn from a vehicle interior and heated is blown to the assembled battery through a battery guide passage. When the humidity of the detected air exceeds the predetermined humidity, an air that has been drawn from a vehicle exterior and heated by a vehicle air conditioning apparatus is blown to the assembled battery through the battery guide passage.

  • Patent number: 9180750
    Abstract: A vehicular thermo-control device adjusts a temperature of a battery. The device has a primary system through which cooling water circulates, and a secondary system through which a refrigerant circulates. The primary system has a heat exchanger which performs heat exchange between the battery and the cooling water, and a heat exchanger which performs heat exchange between the cooling water and an ambient air. The secondary system is a refrigerating cycle. Both heat exchangers on a high temperature side and a low temperature side of the refrigerating cycle are thermally coupled with the primary system. Only one heat exchanger provides heat exchange with the ambient air. The pump of the primary system can switch circulating direction of the cooling water. A controller controls devices to perform cooling and heating operation.

  • Publication number: 20150295285
    Abstract: In an operation mode for heating battery air, a refrigerant passage switching portion switches over to a first refrigerant passage in which a refrigerant including gas refrigerant flowing out of an interior condenser flows into an auxiliary heat exchanger through a first pipe having a relatively large passage cross-sectional area and a liquid refrigerant flowing out of the auxiliary heat exchanger flows to an inlet of an exterior heat exchanger through a second pipe having a relatively small passage cross-sectional area. Meanwhile, in an operation mode for cooling the battery air, the refrigerant passage switching portion switches over to a second refrigerant passage in which a liquid refrigerant flowing out of the exterior heat exchanger flows into the auxiliary heat exchanger through the second pipe and a gas refrigerant flowing out of the auxiliary heat exchanger flows to a suction port of a compressor through the first pipe.

  • Publication number: 20150191072
    Abstract: A refrigeration cycle device includes an air heat exchanger that heats air to be blown into an interior of a vehicle compartment using refrigerant discharged from a compressor, a high-stage side expansion valve decompressing the refrigerant flowing out of the air heat exchanger, and a battery heat exchanger that heats air to be blown to a battery using the refrigerant decompressed by the high-stage side expansion valve. In an air heating-warming up mode of heating the air for the interior and the air for the battery, a refrigerant discharge capacity of the compressor is controlled such that an air temperature for the interior approaches a target air temperature, and an opening degree of the high-stage side expansion valve is controlled such that a battery temperature becomes within a predetermined reference temperature range. A selector switch allows a passenger to select which operation of air conditioning or warming-up is prioritized.

  • Publication number: 20150121939
    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.

  • Publication number: 20150101789
    Abstract: First circulation portions switch a flow of a heat medium such that one of the heat media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat medium such that the heat media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat medium so as to form a first circulation circuit for allowing the heat medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat medium to circulate among the first flow path group, the second flow path group, and a second pump.

  • Publication number: 20150017492
    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.
