The commissioning of an air conditioning system requires a series of manual steps, which leads to inefficient commissioning. A method is therefore provided for commissioning an air conditioning system of a vehicle, including the following: a) Reading in a target data record indicating a target vehicle state; b) Recording an actual data record indicating an actual vehicle state by measuring at least one signal and/or communicating with at least one vehicle component; c) Comparing the actual vehicle state with a target vehicle state; d) Activating at least one function of the air conditioning system only if the actual vehicle state corresponds to the target vehicle state.

An embodiment provides a vehicle heating device for heating a vehicle interior through heat radiation or heat convection using a heating unit connected to an air-conditioning casing. Accordingly, the vehicle heating device may improve the performance, efficiency, and quality in heating the vehicle interior through at least any one of heat convection and heat radiation using the heating unit.

A fuel gas-operated vehicle heater includes a burner area with a combustion chamber (60) formed in a combustion chamber housing (58). The combustion chamber housing (58) includes a circumferential wall (62) defining the combustion chamber (60) in relation to a housing longitudinal axis radially outwards and a bottom area (64) axially defining the combustion chamber (60). The bottom area (64) has a fuel gas feed chamber (116) between a first bottom wall (106) defining the combustion chamber (60) and a second bottom wall (112). A fuel gas feed line (118) opens into the fuel gas feed chamber (116). A fuel gas inlet opening assembly is provided in the first bottom wall (106) for the entry of fuel gas from the fuel gas feed chamber (116) into the combustion chamber (60).

A device for determining a temperature of a resistance heating device, the device includes: a temperature sensor configured to detect the temperature of the resistance heating device; and an electronic data processing and/or control device configured to calculate a temperature change of the resistance heating device on a basis of a change in a resistance value of the resistance heating device and a relationship between the resistance value and the temperature of the resistance heating device, the electronic data processing and/or control device configured to validate the temperature of the resistance heating device detected by the temperature sensor, taking into account the calculated temperature change of the resistance heating device.

A trim element includes at least one support layer having an inner face and an outer face and at least one functional layer made from a carbon material extending over at least part of the inner face or over at least part of the outer face of the support layer. At least part of the functional layer defines at least one heating element formed by a pattern that includes at least one conductive area made from carbon material and at least one nonconductive area formed by a through opening in the functional layer, the conductive area being supplied by a current source electrically connected to the conductive area.

A heating device for heating fluids, such as water or a liquid coolant, for application in electric or hybrid vehicles, where the absence of an internal combustion engine or its shorter time of use requires using heating devices for heating either the passenger compartment or other parts of the vehicle that require it. The heating device is provided with a configuration which limits the temperature to the temperature at which heat exchange occurs between the heat generation source and the liquid to be heated, such that the liquid does not generate precipitates, prolonging the service life of the device.

A method for operating a fuel-operated vehicle heater, wherein after receipt of a switch-off signal by a control unit of the fuel-operated vehicle heater, a shutdown phase is initiated, during which remaining fuel present in the fuel-operated vehicle heater is combusted, and wherein a restart phase is initiated by the control unit after receipt of a switch-on signal during the shutdown phase, without the shutdown phase being terminated after complete combustion of the remaining fuel.

An operating method for an electric heater may include heating a fluid passing the electric heater to an outlet temperature by at least one heating element and operating the electric heater in one of a normal mode or a protection mode. In the normal mode, the at least one heating element may be supplied with at least one of a direct current and a direct voltage. In the protection mode, electrical power supplied to the at least one heating element may be regulated by pulse width modulation. The electric heater may be operated in the normal mode if a reference temperature is less than or equal to a critical temperature and in the protection mode if the reference temperature is greater than the critical temperature.

A heater device includes a heater surface facing one side in a predetermined direction. The heater device includes a transmission electrode and a reception electrode arranged on the other side in the predetermined direction with respect to the heater surface, and an insulation coating layer that covers the transmission electrode and the reception electrode on the one side in the predetermined direction. The transmission electrode and the reception electrode are electrically connected to a contact detection unit, to detect contact or proximity of an object to the heater surface by a change in a capacitance therebetween. The insulation coating layer has a first component part made of an insulating member, and a second component part having a smaller relative permittivity than that of the first component part. The second component part is located between at least one of the transmission electrode or the reception electrode and the heater surface.

Radiant heating systems are provided for warming an occupant of an enclosed space. The system includes a component with a surface configured to face the occupant. The surface defines an A-surface quality meaning the surface is visible and is designed with styling objectives to have an aesthetic appearance. Conductive strands are exposed at the surface and a power supply is configured to supply electric power to the conductive strands. A controller is configured to control the electric power supplied to the conductive strands.
