A control system includes a manual-type air conditioner, and a control device which causes the manual-type air conditioner to execute remote air conditioning in response to a command from outside of a vehicle. The control device starts actuation of the manual-type air conditioner with a maximum temperature as a target blowout temperature of an air-conditioning air and a maximum air quantity as a target air quantity in response to a trigger command of the remote air conditioning, and gradually changes and reduces the target air quantity while gradually changing the target blowout temperature toward a target intermediate temperature with elapse of time. The control device changes the target blowout temperature and the target air quantity respectively to a set blowout temperature and a set air quantity at a time of previous disembarkment, when boarding of a user to the vehicle is detected.

An auxiliary heater with a casing enclosing internal components which components include a heat exchanger separate from and outside the coolant tank and wherein two coolant loops each have their own coolant pumps and wherein a potable water loop exchanges heat with coolant within the heat exchanger. A control circuit provides enhanced coolant flow through the heat exchanger when the call for hot water is significant without significantly reducing the temperature of the hot water being used. A level switch within the coolant tank prevents coolant pumps from running without pump coolant and a filling and air purging operation improves the initial filling operation of the auxiliary heater with coolant and also prevents the coolant pump from running dry. A user switch may dedicate the hot coolant from the coolant tank to either the production of hot potable water or it may share both hot water and space heating.

A fluid heating system intended for use in recreational vehicles that circulates glycol in a system loop with various heat sources and other devices that distribute this heat to an enclosure or a domestic water system. It has a system controller operationally connected to a remove tactile display unit that allows for the input of the operation parameters to the system controller. The control unit is operatively connected for data and signal transfer to the user's cell phone via a non-internet connected localized wi-fi network. This provides the user with system status information, fault codes and allows selected operational functions and resets to be remotely initiated that heretofore required local manipulation. It also incorporates altimeter to allow the furnace controller to maximize its burn efficiency.

A method is provided for operating a fuel-operated vehicle heater (10) during a start phase of combustion operation. The heater includes a combustion air feed device (26) feeding air and a fuel feed device (22) feeding fuel (B) to a burner area (12) with a combustion chamber (16). An electrically energizable ignition element (32) ignites a fuel/air mixture formed. The method includes energizing the ignition element (32) in a preheating phase prior to the fuel feed, at a time of entry into an ignition phase, detecting electrical resistance of the ignition element (32) and determining a desired resistance based on the electrical resistance of the ignition element (32) detected and operating the ignition element (32) in a resistance-regulating operating mode during the ignition phase such that an actual resistance of the ignition element (32) is in the range of the determined desired resistance of the ignition element (32).

An auxiliary heating system for motor vehicles driven by electric motors and a method for realizing an auxiliary heating function in a motor vehicle having an electric drivetrain.

A vehicle defrosting assembly includes a blower that is positioned in a cab of a vehicle. The blower circulates air within the cab when the blower is turned on. Additionally, the blower is in fluid communication with a defrost duct of the vehicle's air conditioning system. A heater is integrated into the blower to heat the cab of the vehicle thereby inhibiting the formation of frost on the vehicle's windows. A heater battery is coupled to the vehicle and the heater battery is independent from an ignition battery of the vehicle. Each of the blower and the heater is in electrical communication with the heater battery. A solar panel is coupled to an exterior of the vehicle for charging the heater battery when the vehicle is not running.

The disclosure relates to an electric heating device, particularly a parking heater, for a motor vehicle, wherein the electric heating device is configured to be connected to an external system voltage and to be incorporated in an on-board motor vehicle cooling circuit, comprising at least one electric heating element for the delivery of heat to a coolant fluid which is present in the cooling circuit, and a power supply unit for the transformation of the external system voltage. Outputs for battery charging, the operation of a circulation pump or the operation of a vehicle fan.

An electrified vehicle and method for heating a passenger cabin of an electrified vehicle that may include an internal combustion engine in addition to an electric machine and a traction battery for supplying the electric machine control an electric heating element to store thermal energy while the vehicle is connected to an external power source that is also used to charge the traction battery, and to extract stored thermal energy during operation of the vehicle with the electric heating element turned off to extend the electric driving range of the vehicle while also providing heat to the passenger cabin. The electric heating element may positioned and controlled to heat one or more elements directly by mechanical contact, or indirectly by heating a circulating liquid coolant to a temperature above a current or anticipated external ambient temperature.

A control apparatus for a vehicle includes an air conditioner configured to perform pre-air-conditioning for previously air-conditioning an inside of a vehicle cabin before a user gets in the vehicle. The control apparatus includes: a determining unit configured to, when the air conditioner is performing the pre-air-conditioning, determine whether an operation of a heating device or cooling device is required, the heating device and the cooling device being mounted on the vehicle to improve comfort of the user; and a device control unit configured to operate one of the heating device and the cooling device, whose operation is determined to be required by the determining unit.

A heat generating system for a motor vehicle includes a carbon nanotube heating element and a controller. The controller is configured to activate the carbon nanotube heating element in response to a wireless activation signal received from a remote communication device. A related method of heating a passenger compartment of a motor vehicle is also disclosed.
