Prediction of Skin Temperature and Examination of Cooling Effect according to Speed of Electric Standing Fan

Hankyong Chu

Abstract: In this study, the cooling effect of the non-uniform airflow generated from a standing fan flowing around parts of the human body was examined. For this purpose, a thermal manikin was used for the test conducted to derive the values of the convective heat transfer coefficient (hc) on each part of the human body. The derived coefficients were then used for the formulation of an equation expressing hc. The derived coefficients were then employed in an algorithm for human body temperature prediction based on the 'Pierce two-node model' to predict the temperature in 14 areas of human body. The established algorithm was verified by comparing the results with the measurements of skin temperature obtained under a stabilized condition at an indoor temperature of 30℃. The time required for body temperature stabilization had little influence on the results. The results of the analysis showed that the cooling effect on the upper half of the body was greater than that on the lower half of the body. Additionally, the cooling effect of the fan appeared to decrease in accordance with increases in the indoor temperature.
