Abstract:

To reveal the principles of human thermal responses and find out the effects of body parts on whole-body thermal sensation, through a subjective survey, experimental investigations on human responses are carried out when a single body part is thermally stimulated.Cooling airflow is sent to seven body parts, respectively.Totally 94 samples are tested.To eliminate the obvious multicollinearity of thermal sensation among different body parts, the principal component regression approach is adopted to obtain the principal components for the body parts under different experimental conditions.Through regression and analysis of principal components, the weighting factors of the seven body parts are obtained.A predictive model on whole-body thermal sensation is obtained based on the weighting factors.The results show that the different characteristics of trunk and limbs are clearly seen. The weighting factors of local thermal sensation are integrated values, and there is little difference among values of different body parts.
