Experimental study on human thermal comfort under physical activities in winter

Carries out a study and questionnaire to investigate the people’s thermal requirements when taking physical works and tests the mean skin temperature and metabolic rate in winter. Simulates two different types of physical activities. The results show that the change regulation of mean skin temperature along with metabolic rate is different. Through the analysis on thermal sensation vote, establishes a relationship between thermal sensation and environment temperature under physical activities. Obtains the thermal comfort range from 14.5 to 17.5 ℃ under the experimental physical activities (from 1.3 to 2.8 met）.
