Abstract

This paper reports an experimental and numerical study on a sleeping thermal manikin in a room equipped with a mixed ventilation system. In the experimental work, heat loss from the sleeping thermal manikin was measured under different conditions. The supply air temperature was in a range of 20°C to 27.5°C. Apart from the heat loss of the sleeping thermal manikin, the velocity distributions and temperature distributions were also measured in the experiments for subsequent analysis. A numerical model was developed to predict the heat loss from the sleeping thermal manikin. The numerical model was then validated by the experimental results. The results show that thermal comfort levels can be predicted by using a computational fluid dynamic (CFD) model with a high degree of agreement.
