The combined heat transfer of radiation and natural convection is a distinctive feature of infrared heating coatings. This feature makes G THERM's heating coatings highly efficient and economical.
Accurate determination of the values of the power of convective and radiative heat transfer is an important condition for calculating the thermal power of infrared heating coatings.
Calculation example
Initial parameters:
Heating coating temperature: 40 С
Room air temperature: 18 С
Room dimensions: 4m x 5m x 2,5m = 50m3
Heating wall coatings dimensions: 4 x 1m2
Resistance of one heating coating, R: 5 Ohm
Calculation results:
Convective heat transfer energy: Qc = 419,2W
Radiation heat transfer energy: Qr = 496,1W
Required total heat energy output of the heaters: Qt = Qc + Qr = 915,3W
Required heat energy of one heater, Qt1: 229 W
Required current value, I: 6,77 A
Required voltage, U: 229 W / 6,77 A = 33.8 V
Required power supply, P: at least 250 VA
