DESCRIPTION

Technical area

[0001] The present invention relates to a wall heating system having a floor heating element introduced into a wall or a wall element for tempering a room, comprising at least one support board having at least one heat exchanger tube laid thereon in a meandering manner or at least one electrical heating cable,

State of the art

Wall heating from hollow, mostly doppelwctndtgen blocks (clay, limestone, etc.) are known from the prior art, in which a heat exchanger tube is installed in the lower part, which heats the air in the cavity, rises through the cavity and by another Hohikammer cooled down again to warm up and rise again.

[0003] Another form of wall heating is made up of more or less large-sized plates made of gypsum, loam, gypsum fibers or the like, into which heat exchanger pipes are firmly cast. Here one is always bound to the few standard formats of the plates. This type is very less flexible in handling and - due to the low thermal conductivity of Plaf ienmaterials - also very sluggish and usually not suitable for cooling or only partially suitable, especially because of the condensation, which can form what z. B. particularly gypsum and partly also clay permanently damages. Also known from the prior art plates of gypsum fibers or other materials, in which a groove is milled to a - usually thin - receive heat exchanger tube. Due to the low thermal conductivity is also a strong inertia unavoidable.

In addition, wall heating systems are known in which Wärmeta uscherrohre be mounted on clips strips directly on the wall or whole prefabricated pipe register directly on the wall to be plastered with several Lehmschichfen. In this system, a lot of energy is lost through the wall, especially in non-insulated exterior walls. Because of the low thermal conductivity, such a system is also very sluggish and the heat distribution within the wall heating surface is very uneven. [0006] Another modular wall heating system consists of a carrier plate with chamotte putties applied thereon, between which a Nuf remains for receiving a heat exchanger tube. Although chamotte is a good heat storage, but a very poor conductor of heat. The system is relatively sluggish and becomes very unevenly warm, especially at low flow tempera- tures.

In addition to the disadvantages mentioned are in the listed systems, the high space consumption, the sometimes poor adaptability to spatial Begebenhelfen, the Untaugiichkeit for premises with an existing moisture that can not be completely or completely eliminated and also the Untaugiichkeit for a combination with In - Nendämmsysfemen because of potential dew point shift, Schwitz- waterfoiidung or lack of diffusion open to name. Presentation of the invention

[ODOS] The present invention is based on the object to provide a Wandhetzsystem which eliminates the inertia of the aforementioned systems and which is suitable to be fully functional with the lowest possible Voriauf- temperature, for example. Soiare energy (Solart Furthermore, the object of the present invention is to provide a wall heating system which heats the entire wall heating surface not only fast but also as evenly as possible.

According to the invention the above object is achieved according to the preamble of claim i in conjunction with the characterizing Merkmaien. Advantageous embodiments and further developments of the wall heating system according to the invention are specified in the dependent subclaims.

According to the invention, a wall heating system of the aforementioned type is characterized in that a graphite-containing heat-conducting layer is applied to the at least one heat exchanger tube, at least one groove 9 for receiving the at least one heat exchanger tube and / or the support plate the at least one electric heating cable is introduced.

[001 1] Depending on the purpose and the structural conditions, the carrier can be made of different materials. For wet walls, it is preferable to use a calcium silicate plate or a peri-plate, since it is resistant to moisture. The Cal- ciumsilikai plate may also absorb a lot of condensation if necessary, for. B. high cooling capacity is required.

For diffusion-open internal insulation is preferably a Hoizweichfaserplatfe in matching strength use. [0013] In the case of "normal" conditions, which do not require internal insulation or have moist walls, other suitable materials may also be used as the support plate, such as, for example, cement-bound peria pialites, waste coverplates, etc.

[0011] In a preferred embodiment of the invention, at least one expanded-graphite heat-conducting plate is applied to the carrier piaite with an ecologically sound adhesive or thin-bed mortar to produce the heat-conducting layer. After setting the adhesive or mortar, a sufficiently great courage is milled into the heat-conducting plate. Subsequently, the finished module is provided with a primer, so that later the plaster will adhere better. After installation of the module, this groove will receive at least one heat exchanger tube, which is plastered with a good heat-conducting material.

[0011] In a further embodiment of the invention, at least one single gra phithaltige Wärmeleifpiatte may be glued to the support plate so that between the plates a groove for the Wärmeta uscherrohr remains.

[00 t ό] in a further embodiment of the invention, the heat-conducting layer can also be formed from at least one graphite-containing heat conducting film. Due to the even higher thermal conductivity of a Wärmeleitfoiie with a preferred W / (m ·) of about 1 80, the thermal conductivity can be improved even in the basic variant described above.

[001 7] Above all, however, a significantly higher thermal conductivity can be achieved in all existing wall heating systems by the use of these foi, which are particularly preferably consist of expanded Gra phit. This allows the use of a variety of materials in conjunction with the graphite foil. Another advantage of the use of expanded graphite for the production of Wärmeieilsciiicht is also dctss this is open to diffusion and ecologically safe. In a further embodiment, large-format, graphite-containing WärmeleitpiaSten are glued to the Trägerpiatie and milled into this a matching groove for the at least one heat exchanger tube.

In a further advantageous embodiment of the invention, the Wärmeleitschichf also a fine-grained or slightly viscous to liquid, graphite-containing matter! soft, which is applied to the heat exchanger tube or the iregerplatfe.

Due to the enormous thermal conductivity of the material used: the entire wall heating surface is heated quickly and uniformly even at very low pre-heating temperatures. This allows the optimal use of solar energy, as it can be used most efficiently if the tempe- rature can be set as low as possible. Temperatures of around 30 ° are almost always stored in the buffer tank when using solar thermal energy, even in unfavorable weather conditions. This opens up completely new uses with solar thermal in the heating sector.

The arrangement of the heat-conducting layer according to the invention further achieves advantages over existing systems, because by their use a particularly low inertia and a very low area consumption (compared to other systems up to 70%) is achieved within a few minutes success! the heat emission by radiation and it is less area required for the same radiant power,

Due to the modular design and the low weight easy handling during assembly is guaranteed. Another advantage of the invention is also in the use of - ό - Of graphite or graphite-containing material existing shielding of electromagnetic radiation by Elekfroleitungen.

Moreover, not only the narrow strips over the heat exchanger tubes are heated by the wall heating system according to the invention, but also the entire area between the heat exchanger tubes. This leads to much smaller Heizungsfiächen. This has, for example, a positive influence in the presence of large wall or window surfaces, which are covered by furniture. Smaller wall heating surfaces also facilitate the installation of wall heaters in fitted kitchens and in smaller bathrooms.

Brief Description of the Drawing Further objects, features, advantages and possible applications of the wall heating system according to the invention will become apparent from the following description of an exemplary embodiment with reference to the drawing. All described and / or illustrated features, alone or in any combination form the subject matter of the invention, regardless of the summary in individual claims or their dependency.

[0027] FIG. 1 shows the wall heating system in a side view with a graphitic heat conducting plate;

2 shows the wall heating system with a Wärmeleitfoüe graphite. Embodiment of the invention

As can be seen from Fig.], The wall heating system according to the invention comprises at least one support plate 2 with a flow and return 3 and at least one heat exchanger tube laid thereon 4. On the At least one heat exchanger tube 4 is provided with a graphite-containing heat layer 5a, into which at least one heat exchanger tube 4 is introduced. The size of the wall heating system modules may vary. The standard format is 60 x 60 cm. But it can also be made much larger formats, even with already plastered Wörmetauscherrohr 4, the flow and return 3 above or unien protrudes and can be easily connected by means of screw or ^' press connection to the Heizkreisiauf.

10031} Fig.2 shows the wall heating system with a Wärmeleittolie 5b

Graphite. The Wärmeleitfoiie 5b can be used according to the invention as follows:

In a Wandheizsystem- odu !, consisting of at least one Trägerpfatte 2, a groove 9 for a heat exchanger tube 4 or an electric heating cable 3 is preferably introduced. Over the entire module surface, a graphite foil 5b made of expanded graphite (possible strengths between 0, 1 and 1 mm) is designed so that a heat exchanger tube 4 or an electric Heizkabe! 3, soft in a nutshell! 9 is inserted, rests on the Graphitfoiie 5b and from this side and bottom touching ⁾ is. As a result, the heat or cold weather is very quickly led, so that between two parallel heat exchanger tubes 4 or electric heating cables 3, the desired temperature is particularly evenly distributed.

Alternatively, the Graphitfoiie 5b also be applied over the entire surface of the support plate incl. The applied heat exchanger tube 4 or the electric Heizkabeis 3 so that they are not under the heat exchanger tube 4 or the electric Heizkabe! 3 is in the groove, but only on top. The entire surface is then primed and can then be plastered or tiled. Even novel large-sized natural stone slabs from only 2-3 mm thick material can as Decor surface to be glued. In this way, a rapid and uniform distribution of the temperature of the entire wall heating surface can be achieved, if, instead of the Wärrneieit plate 5a made of expanded graphite any other for wall heating or air conditioning walls (for heating and cooling) suitable material used (eg chamotte / eramikplätlchen, Gypsum fiber boards, trays, perlite plates, atunsteinpiätfchen etc.},

Instead of the Graphitfoiie 5b very thin plates {1-5 mm) can be glued from expanded graphite over the entire surface in order to achieve a much faster and more uniform temperature distribution.

The wall heating system according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of Ausgesiaftungsvariationen are conceivable, which make use of the solution shown even with fundamentally different type of execution.
