  • Patent number: 9851127
    Abstract: A first outward passage and a second outward passage are branched from a branch portion to guide refrigerants to a first evaporator and a second evaporator, respectively. In the second outward passage with a longer refrigerant flow path of the first and second outward passages, a second decompressor is disposed closer to the branch portion rather than the second evaporator in the second outward passage. Further, a part of the second outward passage located on the downstream side of the refrigerant flow with respect to the second decompressor is defined by an inner pipe of a double pipe, and a part of a second return passage is defined by an outer pipe of the double pipe.

  • Patent number: 9796241
    Abstract: A vehicle temperature control apparatus for controlling temperature of a temperature control object, which is at least one of inside air of a vehicle compartment and a vehicle component, includes a heat capacitive element capable of storing heat, a refrigeration cycle in which heat is absorbed from a low temperature side and is dissipated to a high temperature side, a heat exchanger that causes the heat capacitive element to exchange heat with refrigerant of the refrigeration cycle, and a heat dissipation portion which dissipates heat in the refrigerant of the refrigeration cycle to the temperature control object. Thus, a temperature control by using the heat capacitive element can be effectively performed.

  • Patent number: 9786964
    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.

  • Patent number: 9738133
    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.

    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.

  • Patent number: 9649908
    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.

  • Patent number: 9561704
    Abstract: First circulation portions switch a flow of a heat transfer medium such that one of the heat transfer 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 transfer medium such that the heat transfer 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 transfer medium so as to form a first circulation circuit for allowing the heat transfer 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 transfer medium to circulate among the first flow path group, the second flow path group, and a second pump.

  • Publication number: 20160116197
    Abstract: When a defrosting of an exterior heat exchanger is performed, a refrigeration cycle device switches to a refrigerant circuit, in which a refrigerant discharged from a compressor dissipates its heat at an interior condenser and the exterior heat exchanger, the refrigerant dissipating the heat at the interior condenser and the exterior heat exchanger is decompressed by a battery expansion valve, and then the refrigerant decompressed by the battery expansion valve evaporates at a battery heat exchanger to be drawn into the compressor. Thus, the heat absorbed by the refrigerant from a secondary battery via a battery ventilation air can be used to defrost the exterior heat exchanger, while sufficiently heating the interior ventilation air at the interior condenser.
