The invention relates to a cabin air inlet module (16). The cabin air inlet module (16) comprises a streaming channel body (8). The streaming channel body (8) comprises at least one wall which limits a streaming channel wherein incoming air (5) is supplied to a zone (2) of a cabin (3). The cabin air inlet module (16) comprises an electric heating element (9) which is used for heating the incoming air (5). According to the invention it is proposed that the electric heating element (9) is embodied as a two-dimensional heating element (in particular as a heating paper, a heating web, a heating foil or a heating varnish). The two-dimensional heating element extends along a wall of the streaming channel body (8).

The inventive cabin air inlet module (16) is arranged upstream with a small distance (25) from an inlet opening (6) into the zone (2) of the cabin (3). The inventive cabin air inlet module (16) is used for a tempering zones (2) of a cabin (3) of an airplane according to the needs.

A device for controlling the temperature of workpieces, in particular for drying vehicle bodies, having a housing, a temperature-controlling tunnel accommodated in the housing, and a temperature-controlling system for controlling the temperature of workpieces. The temperature-controlling system includes a full-space temperature-controlling device which can control the temperature of a workpiece as a whole, and a local temperature-controlling device which can control the temperature of locally delimited regions of the workpiece and which comprises multiple temperature-controlling units that can be activated and actuated independently of one another for this purpose. The full-space temperature-controlling device and the local temperature-controlling device are provided in the temperature-controlling tunnel such that a workpiece at least within an active section in the temperature-controlling tunnel can be under the influence of both the full-space temperature-controlling device as well as the local temperature-controlling device. A system and a method for controlling the temperature of workpieces are additionally provided.

An electric heater to heat a flow of a fluid having a jacket block comprising a plurality of longitudinal bores to allow the through-flow of a gas phase medium. An elongate heating element extends through each of the bores that together with the jacket block define a heating assembly to heat the gas. The heating assembly is positionally stabilised within the electric heater via at least one brace configured to inhibit undesirable independent axial and/or lateral movement of the heating assembly within the electric heater.

An adaptable system for defogging a mirror in a steamy bathroom having a tube assembly with a plurality of openings with an impeller and a plurality of heating elements for blowing hot air through the openings onto the fogged mirror. In one example embodiment, the tube assembly has louvers directing the hot air from the openings. The system has a plurality of mounting assemblies configured for all types of mirrors operative for coupling to the tube assembly, such as a portable mounting assembly with a rechargeable battery that selectively attaches on or adjacent to a mirror. The system has an articulated arm mounting assembly in one example embodiment. The system has a mounting assembly fixture in another example embodiment. A kit comprises the tube assembly and at least one mounting assembly.

The present provides a condensing heat exchanger assembly that includes a plurality of heat exchanger passes. The condensing furnace includes a burner assembly having a combustion air device and further includes a frame having primary heat exchanger with a first pass and a second pass. A secondary heat exchanger having a third pass and a fourth pass. The primary heat exchanger assembly may be generally parallel to the secondary heat exchanger assembly such that supply airflow may traverse over the primary and secondary heat exchangers simultaneously in both a first direction and in an opposite second direction. The first pass may include a single drum. The second pass, third pass and fourth pass may include a plurality of aligned tubes.

A furnace has a cabinet having at least one wall at least partially defining an interior space of the cabinet, a heat exchanger disposed in the interior space, and a protrusion formed integrally with the at least one wall, the protrusion extending generally inward into the furnace to at least partially obstruct a circulation airflow through the cabinet.

A system for killing pests in an affected area of a structure comprises a heat exchanger unit placed within an affected area, and a thermostatic control. The heat exchanger unit is configured to receive a flow of water from a faucet, and generate heated air by transferring heat from the flow of water received from the faucet to air flowing through the heat exchanger unit. The thermostatic control is configured to monitor a temperature of the flow of water as it is received by the heat exchanger unit, monitor a temperature of the air as it is received at an inlet of the heat exchanger unit, and automatically cease the flow of water to the heat exchanger unit when the temperature of the air received by the heat exchanger unit is greater than the temperature of the flow of water.
