A Numerical Calculation on the Distribution of Surface Temperature and Thermal Comfort Index caused by Radiation Interaction in a Heated Room

Abstract

As a part of studies to establish a numerical prediction method of thermal environments, this paper presents a numerical calculation on the steady state distributions of surface temperature and thermal comfort index caused by radiation interaction in a heated room with floor panel heating or forced convective heating. Results of the calculation of the room air temperature, surface temperature, vector radiant temperature, mean radiant temperature, Predicted Mean Vote and heat balance illustrate well the characteristics of radiation interaction with the heating systems. This calculation procedure can be combined with the calculation of air convection as shown previously by one of the authors for the two-dimensional case.
