Description

Technical background:

• 1) When electrical energy is used for heating rooms, this is usually done by electrical heaters with filaments or so-called heating wires. Incandescent fibers or heating wires have a high operating temperature usually> 100 ° C. There are several ways to cool them, or control them to limit the temperature and prevent it from causing a fire. In order to reduce the temperature of the heater, fans (forced convection) are used, or the heater is immersed in thermal oil or the like, or the heat is discharged through a corresponding heat dissipation directly by displacement convection to the room air. These filaments or heating wires have a limited service life because of their high operating temperature. The heat of the generating medium is released by induction or heat dissipation via one or more transmitters to the room environment (air). Usually, such devices emit up to 30% of their heat energy as radiant energy and the remainder as convection heat energy to the ambient air.
• 2) Infrared radiant heaters, however, are known for heating purposes as ceiling panels and wall heaters. These often consist on the front of laminates, sheets, glass or the like, which may also be coated if necessary to improve the radiation properties. Nevertheless, the radiation properties are often unsatisfactory, since the resulting radiant energy is considerably impeded in part, depending on the nature of the front in the passage. On the other hand, the heaters in which the radiation is induced by the contact heat of the surface heating elements, the resulting radiation heat in all directions evenly, which leads to a heating of the back and thus to radiation against the desired direction of radiation. An insulating layer as thermal insulation ensures that the heat losses are minimized to the rear, in order to convert a portion of the power thus absorbed into efficient heat radiation and not in convective heat. In this case, a conversion takes place mainly passively by means of contact heat over the surface as a transmitter. Typically, such devices emit up to 40% of their heat energy as radiant energy and the remainder as convective heat energy.

Description:

The development relates to an electrical device for heating rooms by means of infrared radiation component, which is usually suspended above the breast height or head height in the room to be heated, so that the generated induced heat is carried on the surface by natural flow.

The infrared radiation produced by the surface heating element is radiated through the surface to the environment, which directs rear radiation energy through a multilayer reflector which simultaneously acts as a back wall and focuses in the desired direction, thus increasing the energy density in the desired direction of the infrared radiation and the induced residual heat via rear wall consisting of plastic composite material is derived by a further insulating layer in the wall. As a result, the rear wall connection fitting is slightly heated in the area of the space heater.

The space heater, consisting of a simple frame, which serves for screen covering on the front, between canvas covering and surface heating element is an electrical insulation layer, followed by multi-layer reflectors, this work as it were also as a thermal insulation layer and back wall.

The commercial surface heating element or device made of a non-metallic fiber fabric (surface heating element or device are not part of the protection claims) is equipped with an additional temperature switch as a safety switch against - a structurally not possible in normal use - temperature overload and is interchangeable.

The rear wall also serves as a suspension for both vertical and horizontal mounting.

Likewise, the rear wall is also the strain relief of the supplied power cable terminal.

By screwing with the canvas-covered front frame creates a mechanical and thermal load-bearing construction.

The development makes it possible that the temperature of the heater is less than 100 ° C and the canvas cover can be customized or printed with commercially available colors.

The fact that the development of the layered surface in emission and transmission radiation behavior, with the lowest possible power consumption in relation to the surface to be heated, forwards the generated radiation almost without loss through a commercially installed surface heating element. The development allows individual art paintings or prints, made of commercially available colors, to be used as full-fledged space heating, from the point of view of the EnEV 2009 (with valid until today minimum insulation, the consumption below 20 W / m ² , for electric heaters, is).

Purpose of development:

The purpose is to make the benefits of electrically operated space heaters and radiant or infrared space heaters more energy efficient and adapt the increased demands of consumers or users of such systems in addition to space design needs.

With the development is achieved that on the one hand also with artworks an effective space heating is made possible. And on the other hand by several different effects, such as the improvement of the energy density in the radiation with lower energy input a higher surface temperature of the emitting ambient walls or in-body space can be achieved and vice versa at constant room temperatures, a reduction in the energy power entry is effected. In addition, the residual or waste heat emitted directly to the wall connection, which is usually discharged via natural convection by means of loss transfer first to the circulating air and then correspondingly to the surrounding surface, brings about savings.
