Experimental Verification and Analysis of Thermal Comfort with Radiant Floor Cooling

Radiant floor cooling is a new energy saving air conditioning. In recent years, radiant floor cooling effect and its thermal comfort are still in the exploratory period in China. The body's comfort evaluation methods are briefly described in this paper. The indoor temperature and wall temperature of the building envelope determination method is analyzed. Nanhui Art Hall is used as object of study in this paper. Combined with the radiant floor cooling experiments, and using fanger formula calculation, the thermal comfort is calculated. Proper analysis of the results is in two aspects: the clothing thermal resistance and indoor air humidity. With the floor surface temperature below 21.56 °C, and air humidity 55% to 65%, it can meet the requirement of thermal comfort. The result will provide a helpful reference to energy-saving technologies and energy-saving equipment.
