A vehicle heating device includes a heat storage material, a heat recovery unit, a footrest, and a heat controller. The vehicle heating device heats an occupant with heat stored in the heat storage material. The heat recovery unit recovers thermal energy from at least one of a heat source generated by a vehicle or a natural heat source from outside of the vehicle. The heat storage material stores the recovered thermal energy. The footrest is provided at a front portion of a vehicle seat disposed in a vehicle cabin, and has the heat storage material packed inside a heat insulating material. The heat controller heats the footrest by radiating the heat stored in the heat storage material at a predetermined timing with respect to the occupant to be on the vehicle.

Vehicle air conditioning device of a heat pump system in which comfort is compatible with decrease of power consumption. The vehicle air conditioning device includes a heating medium circulating circuit 23 to heat air to be supplied from an air flow passage 3 to a vehicle interior, and in a heating mode, a controller has an energy saving prior mode in which the controller operates a compressor 2 at a maximum number of revolution and complements a shortage of a heating capability by a radiator 4 with heating by a heating medium-air heat exchanger 40 of the heating medium circulating circuit 23, and a comfort prior mode in which the controller limits a number of revolution of the compressor 2 and complements the shortage of the heating capability by the radiator 4 with the heating by the heating medium-air heat exchanger 40 of the heating medium circulating circuit 23.

A heater unit emits radiation heat caused by heat generated with a heat generation unit when energized. The heater device includes a contact detection unit having a contact detection region overlying the heater unit to detect a contact by an object on the contact detection region. The heater device includes a determination unit to determine, when a contact by the object on the contact detection region is detected by the contact detection unit, whether the contact is for a predetermined switching operation. A control unit stops energization of the heat generation unit when the determination unit determines that the contact is not for the predetermined switching operation. The control unit switches between a start and a stop of energization of the heat generation unit when the determination unit determines that the contact is for the switching operation.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include: a casing having an inlet and a plurality of outlets; an evaporator disposed within the casing; a heater core disposed behind the evaporator within the casing; and an air mixing door disposed between the evaporator and the heater core. In particular, the heater core and a rear wall of the casing are spaced apart from each other by a first distance, the evaporator and the heater core are spaced apart from each other by a second distance, and the first distance is greater than the second distance.

An air conditioner for air conditioning a vehicle interior of a motor vehicle, comprising a coolant connection, a refrigerant connection, a condensed water connection, and an air supply channel connection which are each arranged in a front coupling plate and are surrounded by a circumferential seal.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include a heating body positioned inside an HVAC duct of the vehicle, formed between a first electrode portion and a second electrode portion having polarities opposite to each other. The heating body is configured to generate heat when the heating body is electrified to increase a temperature of an air being transported through the HVAC duct.

A thermal management system for a vehicle includes a heating refrigerant circulation circuit, a heat pump cycle and a heat-discharge refrigerant circulation circuit A heating circulation section of the heating refrigerant circulation circuit, a recovery circulation section of the heat pump cycle, and a heat-discharge circulation section of the heat-discharge refrigerant circulation circuit are integrally configured as a combined heat exchanger that is capable of performing heat transfers at least between the cycle refrigerant and the heating refrigerant and between the heat-discharge refrigerant and the heating refrigerant. Furthermore, the heating refrigerant, the cycle refrigerant and the heat-discharge refrigerant are heat mediums each of which has a phase change during the heat transfer.

An air conditioning unit for a vehicle includes a first channel and a second channel, a blowing unit including a first blower fan and a second blower fan that rotate together by sharing a rotary shaft and a driving unit, a bypass channel, and a control door disposed among the outlets of the first channel and the second channel, the heating core, and the bypass channel to control air discharged from the first channel or the second channel to pass through the heating core or not to pass through the heating core through the bypass channel.

Heating device (1), particularly for air conditioning housing of a motor vehicle, wherein the device (1) comprises a heating module (2) configured to heat a flow of air using an electrical current circulating in the module (2), said heating module (2) defining a plurality of zones (7, 8), each zone (7, 8) being capable of heating the flow of air in the direction of one portion of a passenger compartment of said motor vehicle, each of said zones (7, 8) comprising a plurality of heating elements (3) and wherein at least one of said zones (7, 8) comprises a number of heating elements (3) that is different from a number of heating elements (3) heating another of said zones (7, 8).

In a vehicle air-conditioner-unit attachment-part structure, an air conditioner unit is arranged to face a rear surface of a dashboard and on an occupant room side. An air conditioner unit-side fixation part that is provided on a unit case is attached to a vehicle body-side fixed part at a more vehicle rearward position than the dashboard. A displacement acceptance part that accepts a movement to a vehicle rearward direction of the unit case with respect to the vehicle body-side fixed part is provided between the air conditioner unit-side fixation part and the vehicle body-side fixed part when an impact load is input to the unit case via the dashboard from a vehicle frontward direction.
