高温高湿对湿热地区人群热湿反应的影响

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

针对湿热地区夏季高温高湿特点,对人群的热湿反应进行了气候室实验。选取30名大学生作为受试者,在不同高温(29,32℃)和高湿(50%,70%,90%)环境下获取受试者的热湿心理和生理反应。结果表明:温湿度交互作用对人体热湿反应有显著影响,温度越高,湿度对人体热湿反应的影响越大;湿热地区人群90%可接受的新有效温度ET*上限为30.3℃,80%可接受的ET*上限为32.3℃。

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%.
