Abstract: A device temperature adjusting apparatus in which working fluid circulates is mounted on a vehicle and controls a temperature of a target device. The device temperature adjusting apparatus includes a heat absorbing portion that evaporates the working fluid by causing the working fluid to absorb heat from the target device, and a heat releasing portion condenses the working fluid by causing heat release from the working fluid. The device temperature adjusting apparatus includes a forward path portion that defines a forward flow passage and a return path portion. The heat releasing portion is disposed in an inside air circulation path through which inside air circulates while vehicle interior air conditioning is performed by an air conditioning unit that blows out temperature-controlled air to an interior of the vehicle.

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: Charging of an electrical storage device is completed by operation-starting time while increasing a percentage of a charging time of the electrical storage device in a first time period as compared to a percentage of the charging time in a second time period when the first time period and the second time period are included within a period from when a user sets the operation-starting time to the operation-starting time. A temperature adjustment device is operated such that a temperature of the electrical storage device at the operation-starting time falls within a target temperature range while increasing a percentage of an operating time of the temperature adjustment device in the first time period as compared to a percentage of the operating time in the second time period when the first time period and the second time period are included within the period from when the user sets the operation-starting time to the operation-starting time.

Abstract: A thermal management system for a vehicle includes a high-temperature side pump that draws and discharges a heat medium, a compressor that draws and discharges a refrigerant in a refrigeration cycle, a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the high-temperature side pump, a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the high-temperature side pump and outside air, and a pump control unit that controls an operation of the high-temperature side pump such that the operation of the high-temperature side pump is continued even after the compressor is stopped. Thus, the cycle efficiency exhibited when restarting the compressor can be improved.

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.

Abstract: A refrigerant cycle device for a vehicle includes a compressor which compresses and discharges refrigerant, a discharge capacity control portion which controls a discharge capacity of the compressor. The refrigerant cycle device further includes a noise determination portion which determines whether an audible noise other than a refrigerant passing noise is in a low noise state, and/or a load determination portion which determines whether an air-conditioning thermal load is in a high load state. The discharge capacity control portion performs a gradual activation control in which the discharge capacity of the compressor is set to be lower than that determined in a normal control, when the noise determination portion determines that the audible noise is in the low noise state, and/or when the load determination portion determines that the air-conditioning thermal load is in the high load state, at an activation time of the compressor.

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.

Abstract: A bearing apparatus is capable of stably supplying an appropriate amount of lubricating oil to a bearing with a simple arrangement, even if a peripheral speed of a rotational shaft increases. The bearing apparatus includes a bearing unit for receiving a load of a rotational shaft, a lubricating oil reservoir disposed below the bearing unit, and an oil disk rotatable together with the rotational shaft to scoop up lubricating oil stored in the lubricating oil reservoir. The oil disk has a side surface facing the bearing unit, the side surface having a groove formed therein. An outer-circumferential-side end surface of the groove extends parallel to an axial direction of the rotational shaft, and constitutes a guide surface for changing a direction of movement of the lubricating oil in the groove from a radial direction of the oil disk to the axial direction of the rotational shaft.

The on-vehicle battery is charged using an external power supply located outside of the vehicle. The on-vehicle air conditioner controls the temperature of the vehicle interior and the temperature of the on-vehicle battery. The controller operates the on-vehicle air conditioner in an intermittent operation mode so as to control the temperature of the on-vehicle battery, when the on-vehicle battery is charged using the external power supply.

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.

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: A heat medium discharge side of a first pump and a heat medium discharge side of a second pump are connected to a first switching valve in parallel with each other. Respective heat medium inlet sides of a plurality of temperature adjustment devices are connected to the first switching valve in parallel with each other. Respective heat medium outlet sides of the temperature adjustment devices are connected to a second switching valve in parallel with each other. A heat medium suction side of the first pump and a heat medium suction side of the second pump are connected to the second switching valve in parallel with each other. Each of the temperature adjustment devices is switched between a state in which the heat medium circulates between the device and the first pump, and another state in which the heat medium circulates between the device and the second pump.

Abstract: A controller of a thermal management system for a vehicle controls a first switching valve and a second switching valve to set a battery warming-up state in which a heat medium circulates between a battery-temperature adjustment heat exchanger and a heat-medium heating heat exchanger, and the heat medium does not circulate between a coolant-coolant heat exchanger and a heat-medium heating heat exchanger when both a battery and an engine need to be warmed up. In contrast, the controller controls the first switching valve and the second switching valve to set an engine warming-up state in which the heat medium circulates through between the coolant-coolant heat exchanger and the heat-medium heating heat exchanger while the heat medium does not circulate between a battery-temperature adjustment heat exchanger and the heat-medium heating heat exchanger when a temperature of the battery exceeds a target battery warming-up temperature in the battery warming-up state.

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.
