N2 - To analyze the cooling effect of the standing fan, this study calculated the convective heat transfer coefficient (hc) for each body segment and used the results to find the heat loss of the skin. This study derived hc values through a thermal manikin test, and the results showed that the hc value was the biggest for the head, hand, and arm segments. The hc values were applied to the thermal balance equation to compute the skin’s heat loss. The results were then compared to the user comfort survey that was conducted on the subjects. Thermal comfort zone of the subjects according to ASHRAE standards was -1.2~+0.5, extended in the negative direction. According to an analysis on the thermal comfort and heat loss sensitivity for body segments, the impact of the fan airflow change on the head was the biggest, and that for the left hand and forearm was smaller than for the lower body segments. This study will be useful for a detailed analysis of the standing fan’s cooling effect. To this end, a further study should be conducted to factor in different positions of the fan and the amount of clothing.
