Expression of the radiative heat exchange for the human body and its application to modifying the original WBGT for outdoor environment

SUMMARY In order to calculate mean radiant temperature in an outdoor environment, we had to calculate a hypothetical sky tempe rature from directly measurement or an empirical formula of atmospheric radiation expressed as functions of daily mean air temperature, cloud amount, etc. The aim of this research is to propose new expression for simply calculating the radiative hea t exchange in an outdoor environment. In this paper, we defined the...
