It is advisable to use solar shading on windows, but special consideration sh ould be given to the trade-offs between energy consumption (heating or cooling) The mean radiant temperature is defined as the uniform temperature of an imaginary enclosure in which the radiant heat transfer from the human body is equal NUMERICAL CALCULATION OF MEAN RADIANT TEMPERATURE AND TEMPERATURE ASYMMETRY FOR COMPLEX ROOM GEOMETRY M Prek* University of Ljubljana, Faculty of Mechanical Engineering, Askerceva 6, 1000 Ljubljana, ABSTRACT Radiative heat losses represent a substantial part of the total heat balance of the human body in a closed space. The concept of the mean radiant temperature (Tmrt) allows the study of radiative exchanges between a human and its environment.

Outside dry-bulb temperature - site data. Most radiant floor heating systems we've examined run at around 115F water temperature entering the tubing of the radiant section, and you'll see by the temperature gauge at the top of this article that 115 °F was the factory default set temperature on the control of an electric radiant heat boiler we installed. Trmrt - Mean radiant temperature.

If the mean radiant temperatures were found to be too low, then special measures would have been required to improve them. As the radiant temperatures have turned out high, this exercise is unnecessary.
