Relation of sexes and thermal comfort in non-air-conditioned environment

Within a period of one year, conducts a questionnaire survey in more than six hundred students of a university in Changsha, and measures some related air parameters on the spot. Analysing collected data, finds that chillness-tolerance of females is poorer than that of males, that the predicted effect of thermal sensation is not accurate by predicted mean vote (PMV) index, that evaluation on humidity sensation for males and females is almost the same except in a low-temperature environment where females are more sensitive to humidity than males, that draught sensation of females is more obvious than that of males, and that thermal comfort evaluation is affected by more environmental and psychologic factors besides thermal and humidity sensations.
