Effect of indoor air temperature on thermal sensation with seasonal variation

Abstract

In order to understand the changes in human thermal sensation in different seasons in cold regions. The data on skin temperature and indoor environmental parameters(of the head, back, chest, upper arm, forearm, hand, thigh, calf, and ankle)were obtained by field test and questionnaire survey in four seasons. The results showed that the parts which had the greatest influence on thermal sensation were different in different seasons. Spring forearms have the greatest most significant on overall thermal sensation. The palm has the greatest influence on the overall thermal sensation in summer. In autumn, the calf has the greatest influence on the overall thermal sensation. In winter, the back has the greatest influence on the overall thermal sensation. The local thermal sensation varies in different seasons under the influence of physiological and environmental factors, so careful consideration should be given to improving people’s thermal sensation in different seasons. In different seasons, affected by individual differences, the thermal comfort of the whole body is lower than that of all parts of the body. This study can provide a theoretical basis for people to obtain higher thermal sensations in different seasons.
