The process of heating with infraredradiation occurs due to its physical properties. Basically, such as reflectivity, the ability to absorb various surfaces and substances, transmission, scattering, etc. For example, air consists of molecules of nitrogen and oxygen, almost does not absorb, but diffuses partially and easily passes such radiation. The human body, like any objects in the room, for the most part absorbs electromagnetic waves from this part of the spectrum, only partially reflecting them.
In the process of infrared radiationelectromagnetic energy is transformed into thermal energy. Thus, any objects in the room, being heated, give this energy to the air, as a result of which it is heated.
With infrared heating, conversion flowsreduce their speed by an order, and rays, getting on a human body, activate its peripheral circulatory system, which causes thermal comfort at 3-4 ˚С earlier than with conventional convector heating. Being the most useful part of the solar spectrum, the emitted rays compensate for "solar hunger".
That is, any heated object issource of infrared radiation. The wavelength of such radiation determines the molecular composition and temperature of the object. This determines the amount of energy received. Another example of such heating is the Sun, which warms our Earth. This is the most powerful source of the solar system. The sun is its natural heater. All that lives on the Earth is vitally necessary for solar heat, and mankind is no exception. Infrared solar rays pass billions of kilometers in space and at the same time their losses are minimal. Any surface encountered on their way is heated, absorbing the energy of the rays and turning into heat.
The most comfortable for people are long waves. Since the range of infrared radiation itself is large enough, the scientists divided it into three sub-ranges:
The hottest objects emit shorter wavelengths. The warmer the object, the shorter the wave.
Heating PLEN is an alternative to streetheating system, which is used by nature. The ceiling mounted PLEN system allows you to get thermal comfort in the same way that gives it to the entire living Sun. The long-wave radiant energy radiated by the heating elements heats the objects, the floor, the machines, which, in turn, accumulate it and then give it to the environment. At the same time, the humidity of the air remains natural.
That is, the meaning of what has been said amounts to the fact that in order to make the room warm, it is absolutely not necessary to heat the air in it.
PLEN stands for "film radiantelectric heater. "This is a system of infrared heating consisting of a resistive radiating element located between polymer films.The basis of the PLEN system is the interaction of infrared radiation with various matter and its physical properties.
Resistive element is called becauseconsists of several layers of resistor circuits (resistances). When the PLEN heating is connected to an electrical network, then an electric current flows through the resistors, and they are heated to a sufficiently high temperature - 40-50 ° C. In this case, the material from which the resistors are made, can emit infrared radiation. And in order for it to go on heating the room, before laying the PLEN, a foil is placed from the ceiling, walls, floor or other surface, which reflects the directed beams.
While the resistor is warming up, it leavesless than 10% of the time that is needed to warm up the entire room. Within 1-2 hours the temperature increases by 10 degrees - this is the minimum interval. Then the PLEN heating system continues to maintain the set temperature and is switched on periodically for 3-15 minutes during each hour.
Even the best heater can notwork properly if they are not managed correctly. Heating system PLEN, as a rule, consists of a heater and a control unit. The required temperature is set by the thermostat. The thermoregulator installed in the room itself controls its ambient temperature with the built-in temperature sensor and controls a special unit, according to the difference between the actual and specified values.
In addition, if the room is properly insulated, the PLEN uses less power.
There are no special restrictions on the application of the PLEN. It is used both as basic and as additional heating. Possible installation on the floor, walls, ceiling. When using PLEN heating as the main heating, user reviews confirm this, it is enough to cover only 75% of the ceiling or floor. They are heated apartments, cottages, industrial premises, offices, loggias, etc.
The highest efficiency PLEN shows in places where there is a maximum air exchange.
Infrared heaters are not only suitable fornew buildings, but also for the reconstruction of existing ones. Having chosen PLEN heating, it will be possible to save substantially at the design stage. Do not have to build a special boiler room or allocate one of the premises of the house for it. Also, you do not have to think through a scheme for storing fuel, be it coal, firewood or diesel fuel. In the house there will never be a smell of burnt coal or diesel fuel. In addition, the appearance of the house will not be spoiled by radiators sticking out of the walls and pipes that are inherent in traditional heating. And the main thing is that the IR-heaters will remove the dampness in the minimum period, maintaining a comfortable temperature in all the individual rooms.
The most suitable heating system forintended for children of premises is PLEN. Heating of this type is fireproof and convenient. It is not subject to mandatory certification, does not cause the dust to fly in the air, convection drafts and creates the effect of a "warm floor", and therefore protects children from hypothermia.
This system is resistant to low temperatures - it works well even at -60aboutC. It usually closes about 70-80% of the ceiling.
Studies conducted by scientists have shown thatthe human body is most beneficially influenced by long-wave infrared radiation, and in particular its part adjacent to the middle sub-band is the "rays of life", whose wavelength is from 5 to 15 μm. Just in this gap and works infrared heating PLEN. In the same range is the thermal radiation of the human body. Back in the sixties, Japanese scientists on the basis of these discoveries patented the radiators of a special design, subsequently used in infrared saunas. For decades, scientists have conducted joint research and proven the benefits of procedures obtained in infrared cabins. There was IR-therapy. Thanks to it appeared and heating PLEN. The feedback of those who used this heating system show that it proved to be an effective and rather effective way of fighting not only colds, but also with excess weight problems. It also perfectly stimulates the activity of the stomach and helps to get rid of cellulite.
Accordingly, any talk about the dangers of infrared radiation for human health is a fantasy, and nothing more.
PLEN - heating the house, comparable with heatinglight rays. To achieve uniform comfortable lighting in the room, you can only distribute the light sources correctly. The same applies to infrared emitters. When designing an infrared heating system, one should rely on the height of the ceilings, such as the room itself and its area. Then afterwards you will not have to complain about uneven heating.
