Influences of high temperature and humidity on thermal and humid responses of people in hot-humid areas

Studies the thermal and humid responses of the people through a climate chamber experiment according to the high temperature and humidity characteristics of the summer conditions in the hot-humid areas of China. Recruits thirty university students as subjects, tests and obtains their subjective and physiological responses in six experimental conditions with different temperatures and humidities, including 29 ℃/50%, 29 ℃/70%, 29 ℃/90%, 32 ℃/50%, 32 ℃/70% and 32 ℃/90%. The acceptable results show that the interaction of temperature and humidity significantly impacts on human thermal and humid responses, and the impacts of humidity become greater under higher temperature conditions. The upper limit of ET* for 90% of people in the hot-humid area is 30.3 ℃ and 32.3 ℃ for 80%.
