Description
Research as to the conventional indoor wall heat transfer coefficient is restricted to the local or wall average heat transfer coefficient, and such research programs on the measurement of the heat transfer coefficient for indoor wall joints are very few. The purpose of this study is to develop the measurement method for heat transfer coefficient distribution on a wall surface, using a radiant energy thermometer in order to clarify the heat transfer coefficient characteristics on the wall joints using the measuring method thus developed.
The measurement method is characterized in that the surface temperature on the wall of a neoprene model structure attached to an aluminum thermostatic water tank is measured with a radiant energy thermometer in order to find the convective heat flux density according to the difference between the front and rear surface temperatures on that wall of the neoprene model structure and heat conductance. In this report, careful consideration was give to the method for measuring the heat transfer coefficient with a radiant energy thermometer, and heat transfer coefficient characteristics for a joint (ceilling height 2m) of two equal temperature walls, ceilling and floor surface.
