Abstract
The results of a numerical analysis of the parameters of a radiant heating system with radiating panels are presented. The effect of the shape and dimensions of the panel, surface material and the presence of thermal insulation are numerically investigated. It is found that the device of re-radiating panels reduces the surface temperature to 450-500°C, but the increase in the surface area of the radiator provides a more uniform radiation intensity over the heated area, not exceeding the permissible parameters according to sanitary and hygienic requirements. The panel device is found to transform the parameters of the short-wavelength radiator into a more comfortable long-wavelength radiator mode.
