Abstract: An air conditioner includes: a heat-medium air heat exchanger that exchanges sensible heat between a heat medium having a temperature adjusted by the heat-medium temperature adjuster and ventilation air blowing to a space to be air-conditioned; a heat transfer portion having a flow path through which the heat medium circulates to transfer heat with the heat medium having the temperature adjusted by the heat-medium temperature adjuster; a large-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat transfer portion; and a small-inner-diameter pipe that forms a heat-medium flow path between the heat-medium temperature adjuster and the heat-medium air heat exchanger. The small-inner-diameter pipe has small inner diameters ?H and ?C, compared to the large-inner-diameter pipe.

Abstract: An air conditioner for a vehicle includes a pump that draws and discharges a heat medium, a cooler core that exchanges sensible heat between the heat medium and ventilation air into a vehicle interior to cool and dehumidify the ventilation air, a heat-medium and outside-air heat exchanger that exchanges sensible heat between the heat medium and outside air, a compressor adapted to draw and discharge a refrigerant in a refrigeration cycle, a heat-medium cooling heat exchanger that cools the heat medium by exchanging heat between a low-pressure side refrigerant in the refrigeration cycle and the heat medium, and first and second switching valves that switch between a first dehumidification mode for circulation of the heat medium between the cooler core and the heat-medium cooling heat exchanger and a second dehumidification mode for circulation of the heat medium between the cooler core and the heat-medium and outside-air heat exchanger.

Abstract: A vehicle thermal management system includes a switching portion that switches between a state in which a heat medium circulates through a heat-medium cooling heat exchanger and a state in which the heat medium circulates through a heat-medium heating heat exchanger with respect to each of an engine heat-transfer portion and a heat-generating device, a flow-rate adjustment portion that adjusts the flow rate of the heat medium for each of a heat-medium outside-air heat exchanger and the engine heat-transfer portion, an air-conditioning requesting portion that makes a cooling request for an air cooling heat exchanger to cool the ventilation air as well as a heating request for an air heating heat exchanger to heat the ventilation air, and a controller that controls an operation of at least one of the switching portion, a compressor, and the flow-rate adjustment portion based on presence/absence of the cooling request and presence/absence of the heating request from the air-conditioning requesting portion.

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: 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 power storage device includes a case in which at least one unit cell is housed; a heat exchanger (31) that is provided in a wall surface of the case so as to face both an inside of the case and an outside of the case, and that performs heat exchange between the inside of the case and the outside of the case; and a plurality of dividing members (21, 22) that are arranged in an up-down direction inside the case so as to be opened and closed independently of one another, and that divide a space inside the case into a space in which the at least one unit cell is housed and a space in which the heat exchanger is arranged.

Abstract: A temperature control system includes an on-vehicle battery, on-vehicle air conditioner, and a controller. 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.

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.

Abstract: A battery case within which a battery is housed includes a first layer that is made of metal, a second layer that is made of heat insulating material, and a third layer that is made of phase-change heat storage material. The second layer is closer to the battery than the first layer is. The third layer is closer to the battery than the second layer is.

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.

The battery temperature regulating device includes a heat transfer unit that transfers heat of a part of the battery groups to another battery group.

Abstract: A cooling system constructed to cool down an accumulator mounted on a motor vehicle is herein presented. The cooling system sequentially controls an air blower to restrict the air blow to the accumulator, controls the air blow mode switchover module to switch over the active air blow mode after restriction of the air blow to the accumulator, and controls the air blower to release the restriction of the air blow to the accumulator after the switchover of the active air blow mode by the air blow mode switchover module.

Abstract: The position of a damper is changed over to switch over the cooling mode between an inside air intake mode and an A/C intake mode. In the inside air intake mode, the air inside a passenger compartment of a motor vehicle is taken in and directly blown to a battery by the operation of a battery blower fan. In the A/C intake mode, the air cooled down by an air conditioner (evaporator) is taken in and blown to the battery by the operation of the battery blower fan. When the detected vehicle speed V is not lower than a preset reference speed Vref, the position of the damper is immediately changed over (steps S240 to S260). When the vehicle speed V is lower than the preset reference speed Vref, on the other hand, the operation amount of the battery blower fan is restricted to a preset limit level Qlim, prior to the changeover of the position of the damper (steps S220 to S260).
