Radiation thermal infrared
تاریخ discover waves of heat to Sir William Herschel, astronomer (Dick, Wm Sir ) in the year 1800 ad. He to the help of a prism splits light and the thermometer was noticed that the waves, About of the sun, after the analysis by the Charter in the Color Blue has the lowest temperature and in the spectrum, red has the highest temperature .
تمام energy that we get from the sun from a distance of 149 million km, we get, through electromagnetic waves ( electromagnetic )
icon in about 3% of the electromagnetic waves received from the sun's ultraviolet radiation, which is carcinogenic and is about 50% of the electromagnetic waves for visible light is about 47% of the waves for wavelengths, infrared can be, and we talk about the same episode ( infrared ). The heat of the sun through the waves, radiation, infrared, reaches the ground.
روش radiant heating inspired by nature. All objects, physical able to absorb and emit energy by electromagnetic waves are, and the amount of energy emitted to the temperature difference between the objects depends on the parameter to measure the heat energy of the object .
icon about the nature of the function of heating devices, radiation can be said when the temperature of the emitting a rise, the range of short wavelength becomes and frequency increases. The point to note is that all of the material, wavelength, energy, electromagnetism, the same does not absorb, but any material with regard to ماهیتش over the most absorption of electromagnetic energy at particular wavelengths.
