Disclosed is a heating module (12) for a heating system (10) of a habitable vehicle, the module comprising: a module housing (36) having an air inlet opening (56) and an air outlet opening (58); an air conduction element (76) which is accommodated in the module housing (36), has multiple conduction sections (92, 94, 96), and is connected to the air inlet opening (56) and the air outlet opening (58); and at least one heating element (110, 112; 210, 212), said heating element (110, 112; 210, 212) being designed to heat air flowing from the air inlet opening (56) to the air outlet opening (58).

A vehicle oxygen generating system includes a heat source, a power source, a vehicle air handling assembly of a vehicle air conditioning system, an H.sub.2O source and an electrochemical oxygen producing device. The oxygen producing device is connected to the H.sub.2O source receiving H.sub.2O therefrom. The oxygen producing device uses heat from the heat source and electricity from the power source to produce H.sub.2 and O.sub.2 from H.sub.2O. The O.sub.2 produced by the oxygen producing device is directed to the vehicle air handling assembly and moved into a passenger compartment of a vehicle.

A cooling and battery cooling mode is performed to release the heat from the refrigerant in a heat releasing unit and an outdoor heat exchanger and to absorb the heat into the refrigerant in a heat absorbing unit and a refrigerant-heat medium heat exchanger, and a heating and battery cooling mode is performed to release the heat from the refrigerant in the heat releasing unit and to absorb the heat into the refrigerant in the outdoor heat exchanger and the in-vehicle device heat exchanger. In a case where the cooling and battery cooling mode is performed, when a temperature of the heat absorbing unit is lower than a target value of the temperature of the heat absorbing unit even though the flowing of the refrigerant into the heat absorbing unit is blocked, the operation mode is moved to the heating and battery cooling mode.

An electrode carrier of a vehicle heating device applying a CNT composite material includes a first electrode part and a second electrode part having different polarities from each other and formed in a straight line along a length direction of a vehicle; a fixing member configured to fix the first electrode part and the second electrode part to the vehicle; and the CNT composite material formed between the first electrode part and the second electrode part, configured to generate heat when being electrified, and fixed to the vehicle.

A method of operating a vehicle climate system includes, by a controller, responsive to a same blower motor request, operating a blower motor at a first speed responsive to a heater core isolation valve (HCIV) directing coolant used to heat a cabin to an engine. The method further includes, by the controller, responsive to the same blower motor request, operating the blower motor at a second speed less than the first speed responsive to the HCIV directing the coolant to an electric heater and not to the engine.

An impeller apparatus includes a housing, an impeller, and a heat generation member. The housing includes an air duct formed in the housing. The air duct includes a first air duct and a second air duct successively connected to each other. The second air duct has a non-blocking area. The impeller is arranged in the first air duct. The heat generation member is rotatably arranged in the second air duct and has a blocking state and a non-blocking state. In the blocking state, the heat generation member blocks the second air duct, in the non-blocking state, the heat generation member is accommodated in the non-blocking area and does not block the second air duct.

The present invention relates to a heating device for use in vehicles, particularly to a device for heating a fluid, for example air, water, or liquid coolant. The device is particularly designed for vehicles the main propulsion system of which is not a combustion engine and which therefore lack residual heat from the engine. The present invention is characterized by the use of a chassis with a planar configuration and an inner chamber in fluid communication with an inlet port and an outlet port and a heating plate. The chassis comprises at least one window and the heating plate has a heating region closing the window of the chassis for heating the fluid housed in the inner chamber.

An air conditioning device for an electric vehicle includes: a housing having an air conditioning passage connecting an air inlet port to an air discharge port; an evaporator, an air heater, and an electric heater, which are positioned in series in the air conditioning passage in the housing; and a bypass door positioned after the evaporator in the air conditioning passage in the housing and configured to selectively allow some of air passing through the evaporator to bypass the air heater and the electric heater to the air discharge port.

A heating arrangement has a coolant housing with an inflow connection and an outflow connection for a coolant. Heating elements are arranged on opposite housing walls and include connections for the supply of power. Three circuit-board pieces of a circuit board are arranged in a row and connected to one another via flexible regions. Power electronic components and connections for connecting to the power-supply connections of the heating elements are arranged on the two edge circuit-board pieces. The circuit board is bent in flexible regions such that the two edge circuit-board pieces lie opposite one another. The coolant housing lies between the opposite edge circuit-board pieces. The power-supply connections of the heating elements and the connections on the edge circuit-board pieces are in electrical contact.
