An adaptive radiant heating system regulates a climate inside a motor vehicle cabin having a seat for a vehicle occupant. The system includes radiant heating tiles arranged proximate the seat and powered by an energy storage device. The system also includes a first sensor for detecting a position of the occupant and generating a first signal indicative thereof. The system additionally includes a second sensor for detecting a temperature within the cabin and generating a second signal indicative thereof. The system furthermore includes an electronic controller in operative communication with the tiles and the first and second sensors, and configured to regulate the climate proximate the seat via selective control of the tiles. The controller is configured to receive the first and second signals and activate at least one of the tiles in response to the first and second signals, to thereby regulate the climate proximate the seat.

The present invention relates to a vehicular heating device comprising: a vehicular engine cooling unit for connecting an engine, a water pump, and a radiator on a first cooling water circulating line to cool the engine; and a vehicular indoor space heating unit for connecting the engine, the water pump, and a heater core on a second cooling water circulating line to heat an indoor space of the vehicle, wherein the vehicular heating device comprises a heating means mounted on the second cooling water circulating line to heat cooling water supplied to the heater core.

An air conditioning and battery cooling assembly with an A/C coolant circuit and an E-drivetrain coolant circuit as well as a refrigerant circuit, wherein the A/C coolant circuit and the E-drivetrain coolant circuit are coupled together across a 4/2-way coolant valve in such a way that the A/C coolant circuit and the E-drivetrain coolant circuit can be operated separately or can receive a flow in serial manner.

System and methods are provided for improving fuel economy, and providing optimized operating conditions associated with a vehicle's air-conditioning system when the vehicle is carrying a load, e.g., towing a trailer. Operating conditions including, for example, air-mix setting, coolant temperature, ambient temperature, vehicle speed, and whether or not the vehicle is carrying the aforementioned load, may be considered when determining whether or not to activate or deactivate a vehicle heating element, such as a positive temperature coefficient (PTC) heater, steering wheel heater, etc.

A vehicle air conditioner includes a casing, a heater core that heats an air flow by heat exchange between the air flow and a heat medium, an electric heater that heats an air flow by an electric power, and a determiner that determines whether a temperature of the heat medium is equal to or lower than a predetermined temperature. When the determiner determines that the temperature of the heat medium is equal to or lower than the predetermined temperature, an air flow introduced into a casing is heated by the electric heater and flows toward the vehicle interior without passing through the heater core.

The invention concerns an installation for the thermal conditioning of a passenger compartment and/or at least one component of a motor vehicle, comprising a first circuit (1) for circulating a heat transfer fluid, a second circuit (2) for circulating a refrigerant fluid, capable of forming a heat pump type circuit, the heat transfer fluid circuit comprising heating and/or cooling means (M1, M2, M3) for at least one component of a motor vehicle, means (S1, S2) for storing calories and/or frigories, a first exchanger (E1) forming an evaporator and capable of exchanging heat with the refrigerant circuit, and means for circulating the heat transfer fluid capable of drawing the frigories and/or calories from the storage means (S1, S2) or the first exchanger (E1), so as to transfer them to the heating and/or cooling means (M1, M2, M3).

A vehicle includes an engine, a generator driven by the engine to generate an electric power, and a high-voltage battery charged with the electric power. An air heating in a vehicle interior is implemented by waste heat of the engine through which a heat medium is circulated and heated, and an air heating in the vehicle interior is implemented by a heat pump device consuming the electric power of the electric storage device. A hybrid ECU performs air conditioning control, and includes a determination device that determines whether to implement the air heating by the waste heat or the air heating by the heat pump device based on an engine body temperature, and a heating control device that selectively implements the air heating by the waste heat and the air heating by the heat pump device based on a determination result of the determination device.

A heat pump and a heater core are provided at a heating coolant water circuit connected to an engine. As heating thermal amount control, the control of decreasing the output of the heat pump and increasing the output of the engine with an increase in an engine outlet water temperature detected by an engine outlet water temperature sensor, thereby ensuring a target heating thermal amount. Thus, in response to a decrease in a heat generation efficiency of the heat pump with an increase in the engine outlet water temperature, the output of the heat pump is decreased so that fuel economy can be improved while the output of the engine is increased so that the target heating thermal amount can be ensured.

A climate control system and method controls climate at selected regions. The thermoelectric system includes a plurality of thermoelectric assemblies. The system can include a fluid conduit configured to allow a liquid to flow in the at least one fluid conduit. The system can further include a plurality of thermoelectric assemblies. At least two thermoelectric assemblies of the plurality of thermoelectric assemblies are in thermal communication with the liquid to provide climate control to a region.

A method for controlling heating of a hybrid vehicle is provided. The vehicle includes a duct flowing air into the indoor of the hybrid vehicle from the outside, a heater core for circulating the coolant heated from an engine inside the duct, a PTC heater heated by the power supplied from a high-voltage battery of the hybrid vehicle inside the duct, and a controller. The controller operates the engine and the PTC heater and heats the air flowing into the indoor of the hybrid vehicle through the duct. The voltage supplied to the PTC heater from a low voltage DC-DC converter (LDC) is changed based on the state of the engine and an auxiliary battery for supplying power to an electric component of the vehicle to apply power to the PTC heater.
