Proposed are an air conditioner having an integrated heat exchanger and an air conditioning system using the integrated heat exchanger. The integrated heat exchanger enables heat exchange between cooling water and conditioning-air, and generates heating air or cooling air such that cooling/heating efficiency is improved. Further, since the temperature of the cooling water circulating in the integrated heat exchanger is adjusted, there is no temperature adjustment door for adjusting the temperature of conditioning-air, so the number of parts is reduced. Further, since the integrated heat exchanger is applied, components are optimally arranged and the entire package is reduced in size.

An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket, protruding into the heating chamber as a heating rib tapering towards its lower, closed end protrudes. A PTC heating element includes at least one PTC element and conductor tracks for energizing the PTC element with different polarities. The conductor tracks are electrically conductively connected to the PTC element and are electrically connected in the connection chamber. A pressure element is received which holds heat extraction surfaces of the PTC element abutted against oppositely disposed inner surfaces of the receiving pocket. The pressure element includes a sheet metal strip which, by punching and bending, forms spring segments protruding from the plane of the sheet metal strip. The spring elements are provided in a planar manner distributed over a heat extraction surface of the PTC element provided adjoining the respective pressure element.

A vehicle has a climate control system using a heat pump having a condenser heat exchanger that exchanges heat between refrigerant and working fluid within a hot fluid chamber, and an evaporator heat exchanger that exchanges heat between refrigerant and working fluid within a cold fluid chamber. A super-heated fluid pressure vessel may be in fluid communication with the cold fluid chamber by way of a heat exchanger and an electrically controlled variable delivery valve, and has an electric heater that may be powered by a drivetrain battery or by a shore power source. The hot fluid chamber provides heat to at least one cabin heat exchanger and to at least one ambient air heat exchanger. The cold fluid chamber is connected to at least one vehicle interior cooling module, to a waste heat source, and to a cold fluid chamber to outside heat exchanger.

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).

The present invention relates to a heating device for heating fluids, such as water or a liquid coolant, for example, which can be applied in electric or hybrid vehicles, for example, 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 present invention is characterized by 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.

An electrical heating device (1) includes a housing (2, 102) having a fluid inlet (3) for the intake of a fluid to be heated into the housing (2, 102) and having a fluid outlet (4) for the discharge of the fluid from the housing (2, 102). A flow channel (5) for the fluid is formed between the fluid inlet (3) and fluid outlet (4), and at least one heating instrument (6, 105, 205) extends into the flow channel (5) in the housing (2, 102). This heating instrument has a sleeve (7, 207) that surrounds an interior of the heating instrument (6, 105, 205) in a fluid-tight way. At least one heating element (8, 208) is arranged in the sleeve (7, 207), and at least one sensor element (9, 109, 209) is arranged in the sleeve (7, 207) for monitoring the temperature of the at least one heating element (8, 208).
