(57) Abstract:

A method of manufacturing an electric wall panel designed for heating of residential, public and industrial premises infrared beneficial to the human body on biophysical indicators. For the manufacture of electric heating wall panels use a base made of, for example, plasterboard, gipsovolokna, etc. etc. and ensuring the mechanical strength of the panel. On the back surface of the base, put a layer of insulation, and on the working surface, place a flat resistive heating element, which is used shielded electric wire with heat-resistant electrical insulation, which is evenly placed in the form of a spiral, meander or zigzag flat winding and fixed on the working surface of the base. The space between the coils shielded wire fill weight, has good heat-conductive and adhesive properties. On top of mass impose a fine mesh, made of a ferromagnetic material, and on top of the grid put a layer of plaster over the entire front surface is network, and his braid and a fine mesh supply leads for connection to the electrical circuit ground. The front surface of the panel or cover mineral paint or veneer natural or artificial stone, tile or ceramic tile. Perimeter panels install decorative border, which are made of wood, metal, natural or artificial stone, and tile or ceramic tile. Connecting the conclusions braid shielded wire and wire mesh to the contour of the electrical grounding of the building ensures the absence of electric and magnetic fields outside surface of the electric heating panel in accordance with the requirements of ecology. The technical result is the creation of a method of manufacturing the infrared electric wall panel providing process simplification of the manufacturing process and eliminating technological limitations of the geometric dimensions in the manufacture of low-temperature infrared heating panels.

The invention relates to the electric power industry, in particular, to the creation of funds for heating of residential, public and industrial premises is the design, construction and reconstruction of heating systems of residential, public and industrial buildings.

Currently, increasingly finds electric heating of residential, public and industrial premises. As shown by experimental studies, the use of electric heating opens up new opportunities for qualitative improvement of sanitary conditions and enhance the comfort level of the human environment. The transfer of residential, public and industrial premises on electric heating is closely linked with the development of new high-efficiency heating means, meet modern technical, aesthetic, ecological and economic requirements. Special attention is paid to environmental requirements, according to which as in the manufacture and practical use of new heating means should not create electromagnetic fields and radiation of that wavelength and intensity differ from those to the effects which man has adapted throughout the historical process of biological evolution.

Currently used convection and radiation (radiation) polnye advantages over convection. (Reference "Builder", ed. HA"NORMA", 2000, 4, pp. 192, 193).

Typical infrared heaters for space heating are electric ceiling infrared heaters "Ecoline". When this ceiling infrared heaters "Ecoline", intended for heating of residential and office space with a ceiling height of up to 3.5 m, are the temperature of the radiating surface from 100 to 200oC. For heating rooms with a ceiling height of more than 3.5 m are ceiling infrared heaters "Ecoline", having a temperature of radiating surface from 300 to 750oC. IR heaters "Ecoline" are characterized by high specific energy density, which is caused by the desire to provide the required power is limited to the relatively small sizes of the dimensions.

A significant drawback of infrared heaters with temperature of the radiating surface from 100 to 200oAnd from 300 to 750oWith is the fact that infrared radiation lying in the wavelength range shorter than 6 microns, characterized by a very low efficiency of interaction with the human body, since the depth of penetration into the human body infrared radiation at these wavelengths is very small. Consequently, all the energy of infrared radiation is spent on agreesto skin, for example person. In addition, the high temperature emitters lead to the fact that in the best case dies microflora of air, and at worst - in the air produced many harmful and even toxic organic compounds, including carbon monoxide.

The effectiveness of the interaction of infrared radiation with the human body is higher, the greater the penetration depth of the IR radiation under the skin surface. The penetration depth decreases with increasing temperature of the radiating surface of the infrared heater and a corresponding decrease in wavelength infrared radiation. According to biophysical studies, the most favorable for the organism is the infrared radiation at the wave length ranging from 8.5 μm to 10.5 μm, and the maximum intensity in the continuous absorption spectrum of the human body has a wavelength in the range of 9.3 to 9.5 μm. At this wavelength has the largest penetration depth of the IR radiation in the human body (Bogolyubov C. M., Ponomarenko, N., General fisioterapia. M, Medicine, 1999, pp. 148-151; Physical encyclopedia. M., 1998, volume 2, page 182). Therefore, because the clothes for these wavelengths translucent, thermal comfort, associated with thermal balance of the human body, comes with ponizhennye feature does not create carbon monoxide environment, but doesn't destroy the microflora of the air.

In order to receive infrared radiation in the wavelength range of about 8.5-10.5 μm, it is necessary to use the IR heaters with a surface temperature of the emitter in the range of 45-50oS. Inevitable in this case a reduction of the specific energy density can be compensated for by increasing the surface area of the radiation of the infrared heater.

The use of high temperature infrared heaters, which are characterized by high specific energy density, dictated largely by the technological limitations of the geometrical sizes of the emitters and opportunities of technological equipment in manufacturing. To solve the introduction of low - temperature infrared heaters, characterized by a large area of the emitter and associated with the binding of their geometrical dimensions to specific areas, the importance of the choice of design and the best technology for their fabrication to maximum readiness in the factory, to effectively monitor the process stability, the characteristics and quality of the finished product. This will completely eliminate the need for making nizkotemperaturno is extremely difficult.

Proceeding from the above, was selected IR heating panel, the configuration and size of which can vary depending on the specific conditions of the optimal solution space heating, and developed its manufacturing technology, which is the subject of this invention.

Structurally, electric heating panel is multi-layered. It contains the basis of ensuring the mechanical strength of the panel and having a layer of insulation from the rear side of the flat heating element, an electromagnetic shield and the outer (front) surface. Built-in control sensor automatically limits the temperature of the outer cover panel at the specified level. Food electric heating panel is plugged in. Temperature control of the heating panel with thermostat.

The closest analogue (prototype) of the inventive method of manufacturing an electric wall panel is a method of manufacturing a radiant heating panels under the patent 2141177 C1 from 10.11.1999, providing for the placement of electrically conductive material on the substrate, which is used deletionstatecode and protective coatings.

The disadvantage of this technical solution is the complexity of the technological process of its implementation, requiring the use of special technological equipment, which imposes constraints on the geometrical dimensions of the IR heaters. Therefore, it can be used for the manufacture of mainly high-temperature infrared emitters is small, operating in the shortwave infrared range at wavelengths that are not optimal from the standpoint of physiological effects on humans.

The objective of the invention is to provide a method of manufacturing the infrared electric wall panel providing process simplification of the manufacturing process and eliminating technological limitations of the geometric dimensions in the manufacture of low-temperature infrared heating panels.

The technical result is the ability to provide thermal balance of the human body at low temperature air in the room and therefore energy savings.

This technical result is achieved in that for the manufacture of electromagnetically Ave, on the back surface of the base, put a layer of insulation, and on the working surface, place a flat resistive heating element, which is used shielded electric wire with heat-resistant electrical insulation, which is evenly placed in the form of a spiral, meander or zigzag flat winding and fixed on the working surface of the base, fill the space between the turns of the shielded electric wire weight, having good heat-conductive and adhesive properties, and then on top of mass impose a fine mesh, made of a ferromagnetic material, and on top of the grid put a layer of plaster over the entire front surface of the panel, moreover, the beginning and the end of the shielded electric wire supply leads for connection to the mains, and his braid and a fine mesh supply leads for connection to the electrical circuit ground. The front surface of the panel or cover mineral paint or veneer natural or artificial stone, tile or ceramic tile. Perimeter panels install decorative border, which vypolnyaem each of these materials is used as separately and in various combinations with other materials. Connect electrical leads braid shielded electric wire and wire mesh to the contour of the electrical grounding of the building ensures the absence of electric and magnetic fields outside surface of the electric heating pad.

The manufacturing process of heating the wall panel on the proposed method does not require the use of special complex of technological equipment. Therefore, electric wall panel can be made in any enterprise of building a profile based on the use of known techniques and methods developed in these enterprises. In this regard, the feasibility of the proposed method of manufacturing an electric wall panel is not in doubt.

Facing the front surface of the panel, natural stone (marble) or manufacture from natural materials ceramics has hygienic, aesthetic, and most importantly curative properties. During heating of the cladding to a temperature of 40-50oWith it radiates infrared emitted is of onki range, determined the mineralogical composition of the cladding, the resonance is absorbed by the human body, and most deeply penetrates into the human body, even through clothing. Property of infrared radiation of a specified wavelength range directly absorbed by the human body helps to ensure thermal balance of the human body at low temperature air in the room and therefore save on power consumption.

Method of making electric heating wall panels, namely, that as a resistive electric heating element, use a shielded electric wire with heat-resistant electrical insulation, which is evenly placed in the form of a spiral, meander or zigzag flat winding and fixed on the working surface made, for example, plasterboard, gipsovolokna, asbestos cement, fill the space between the turns of the shielded electric wire weight, having good heat-conductive and adhesive properties over the masses impose a fine mesh, made of a ferromagnetic material, and on top of the grid put a layer of plaster over the entire front surface of the panel, and nasceu network, and his braid, intended for use as an electromagnetic screen, and a fine mesh supply leads for connection to the electrical circuit ground, while the front surface of the panel cover mineral paint, stones natural or artificial stone, tile or ceramic tile, perimeter panels install decorative border made of wood, metal, natural or artificial stone, and tile or ceramic tile, and each of these materials are used both separately and in various combinations with other materials, and on the back side of the base has a layer of insulation.
