Anna Bondarenko What could be nicer than the feeling of warming sunlight? Only a sense of permanent summer at home! Make it possible at any time, using infrared heating technology. Today's consumers offer a lot of options for heating homes, and the youngest of them - is infrared heating. On what principle it works, and why has become a serious competitor to other heating systems? As the sun began to lay sort out the nature of infrared rays. One of the known infrared emitters is the sun which, at a distance of many millions of miles, warms our earth. Rays of the sun, encountering along the way the surface, are absorbed by it and converted into heat energy. Thus, the propagation of infrared radiation in space is practically no energy losses. The same thing happens in the room: infrared heat, all items are within their actions, and the heat source is everything that surrounds man. In other words, to get a comfortable room temperature, the air is heated it is not necessary. The advantages of infrared heating systems include their cost, which is especially important in connection with the continued growth in electricity prices. Interestingly, if the lower the temperature of the infrared heater a few degrees, the temperature felt by a person remains the same, because the decline will be offset by "radiation" supplement. Thus it is possible to reduce energy consumption and reduce heating costs compared to traditional methods of heating. Decreasing the temperature by just 1 degree gives a 5% saving! It is also important that the infrared heating of the heat stored below, at the surface, not the ceiling, and most of the heat energy is not spent on heating Ceiling useless for the consumer space. In this case, the air will not overheat or get too dry, there is equalization of the temperature between floor and ceiling, which allows for 15-40% energy saving. When operating the infrared equipment, the room air does not circulate, which guarantees the absence of drafts. Also, because of reduced air turbulence is limited to the movement of dust particles, which lowers risk of possible occurrence of various diseases: asthma, inflammation of mucous membranes, etc. The increased temperature of the wall, to reduce the possibility of condensation and humidity did not significantly change. Environmental friendliness and safety - additional trump cards of this method. When designing a system of infrared heating, you must proceed from the height of ceilings, the area and type of premises. For a point heat pressing is an infrared heater or a panel that could at any time to remove and install in another location. For the local heating plant will be the best system in the floor, ceiling or walls (foil, film, rods). Heaters and panels: the warmth of a portable infrared heater as a heating element uses special lamps burning in the spectrum invisible to human and thus emitting large amounts of heat. Compared with other types of heaters, saving up to 70%. Thermal radiation, like a regular light is not absorbed by air, so all the energy from infrared heaters, without loss reaches the heated surfaces and people. The average temperature in the room can be 2-3 degrees lower than optimal, but due to the direct absorption of energy from infrared heaters person within its range will feel comfortable. Many designs of such heaters include a fan, which promotes a more rapid spread of the heated air into the room. Infrared ceiling heaters can be suspended on horizontal ropes or have tilting. This allows us not only to preserve the walls and floors free, but also significantly expand the area of ??heating due to the impact on horizontal surfaces. This ensures the maximum heat effect as a direct air heating (heat loss), leaving only 10% of energy. If the panel is not parallel to the floor, on direct heat will leave 25-30% of energy, hence the thermal efficiency decreases. Heating elements ceiling panels are tubular heaters, which are collected in a panel with an infrared emitter, so that resistors remain visible. Thus, the panels provide heating through radiation of heat. They are best suited for use where heating is required for restricted areas without scattering over the entire area of ??the room. Reflecting heat: Foil recently in the construction market, a new system of infrared heating a house - with the help of the foil made in Finland. The heating element is a thin metal foil, which is located between two plastic films. The principle of operation is very simple: electric current flowing through the foil, increase its temperature to 38 ° C, and that heats the surface of the ceiling or floor (where the foil is installed). In turn, the heated surface, bypassing the air, warms the objects of the room. Since the foil is different specific power and size, it allows you to apply it in different conditions (floor, ceiling) and the premises of various configurations. Using the foil is simply ideal for underfloor heating installation under laminate and cardboard-gypsum wooden ceilings. When mounting the foil on the ceiling, it is installed between the ceiling surface and heat insulator. It is fixed on the crate ceiling. Thus, the thermal energy is transferred almost completely covering the ceiling and into the room. Due to the fact that the ceilings of the houses are different heights, there are two types of foil. The former has a power output 125 W / m and is suitable for all ceiling materials. The second has a capacity of 150 W / m and is applicable for rooms with high ceilings. Residents to feel comfortable and to save energy at the ceiling heating foil using a room thermostat, which measures the air temperature in the room. When installing heating ceilings must comply with the minimum distance from the heating foil: a minimum of 50 mm from the ventilation chimneys, wooden beams and mounting fixtures, at least 200 mm from the electrical fixtures and boxes. Should also keep a distance of 25 mm from the electrical wires, except for proper connection foil. Distance from the wire carrying the timber shall be not less than 50 mm. Foil can also mount to the floor. To this end, it stretches between the flooring and insulation. In this case, between the surface and the foil necessary air gap. As with overhead heating, then heat is transferred to cover, and then, in the form of radiation of heat - the walls, ceiling and furniture. They, in turn, transfer this energy to the air. The main advantage of such a system - a small cost of electricity, which is achieved by high efficiency heating by infrared radiation heating system and control room. It is also a full fire safety and a quick, inexpensive installation. Film heating Another effective home heating technique, which was recently developed by Korean scientists - using infrared film, which can be used as additional or main heating system. Like other systems of infrared heating film element affects all the surrounding area, which reach up to infrared rays. This material is an ultra-thin (about 0.4 mm) polymer film, which radiates from its surface distant infrared light (wavelength May 20 microns).
