Calculation of Thermal Conditions Generated During the Radiant-Convective Heat Exchange Process in a Room of a Building with Enhanced Thermal Protection

Within the regulatory limits, the standards require maintaining the air temperature and the resulting temperature at the border of its serviced area. The resulting temperature is a local indicator, since it includes the radiation temperature, which mainly depends on the location and temperature of the surfaces facing the premises. The article is devoted to the development of a methodology for calculating these indicators in the estimated cold winter period according to experimental data obtained during warmer weather. The article presents the results of measurements of air temperature, the resulting and radiation temperature at an outdoor temperature of -7°C, the values of radiation temperature obtained by calculation simulation of measurements with a globe thermometer and the predicted values of these parameters in the design winter conditions.
