INFRARED
In the electromagnetic spectrum infrared IR rays such as ultraviolet UV are placed at the ends of the field of view. The IR infrared rays have a longer wavelength than visible light and therefore are invisible to the human eye. They manifest themselves in the form of heat because typically the matter, in ordinary conditions, presents a strong thermal absorption for this frequency.
The infrared band is divided into four smaller bands. The bands include:
- near infrared NIR (Near Infrared Ray): 0.75 to 3 µm
- middle infrared MIR (Middle Infrared Ray): 3 to 6 µm
- far Infrared FIR (Far Infrared Ray): 6 to 15 µm
- far infrared XIR (Extreme Infrared Ray): 15 to 100 µm
Although the wavelengths are expressed in uM (micrometers), to measure the wavelength in this region of the spectrum it is often also possible to use other units measurement, such as nanometers (nm) and Ångström (Å). The ratio between the different wavelength measurement’s units is:
10,000 Å = 1,000 nm = 1 μ = 1 micron
The systems of infrared heating allows to concentrate much energy (caloric) on a specific surface area by minimizing the dispersions. The infrared lamps are compact and powerful heating sources; They are also halogen, therefore the performance maintenance remains stable for the life’s duration. After one second the lamp is switched on it reaches full power and equally after a second from the shutdown, this does not emit more heat.
IRRADIATION
Radiation is one of three ways , which triggers the propagation of heat.
- Convection: heat propagation caused by a pressure gradient and by the force of gravity , characterized by convective circulation within the fluid.
- Run: occurs between bodies that are in contact or between parts of the same body that are at different temperatures.
The hot body loses its energy to the cold increasing the temperature until it has reached thermal equilibrium. - Irradiation: means the transfer of energy between two bodies by means of electromagnetic waves.
It does not provide for direct contact between the exchangers and does not require a medium to propagate.
With the units of electrical heating infrared SUNSHINE heat transmission takes place for irradiation and this presents important advantages:
- it transfers the heat only where necessary
- it does not heat the air, but people directly
- the perception of heat is immediate
- the result is uniformity at different distances
- it does not produce odors
- it is free of harmful emissions
- it does not burn oxygen
- creates no lifting of dust
- it is silent
SAVING
Saving units with electric heating infrared SUNSHINE is evident as the cost of heating oil has risen by 50% in three years and to heat buildings, churches, sports facilities and other areas of large cubic capacity has become very expensive, while the costs related to electricity are much lower.
EFFECTIVENESS WITH INSTALLATIONS AT GREAT HEIGHTS
The unit of electric heating infrared SUNSHINE have been designed with a compact and elegant design made of extruded aluminum and with special reflectors bifocal able to radiate the maximum power (over 95%) with installations at great heights as churches, industrial and Sports facilities.
