摘　　要：为确定夏季高温环境下空气流动对人体热舒适性的影响程度,于2008年夏季,进行了吹风环境下人体生理、心理热舒适实验。统计分析表明:夏季高温环境下,吹风使人体生理参数及热感觉出现明显下降的现象,且下降的程度与其所处环境的空气温度有关,相同风速下,空气温度越低,下降程度越大。但当空气温度达到约34℃时,吹风对人体生理参数基本无影响,但对热感觉仍有所改善。研究结果表明:夏季高温环境下,加强空气流动可在一定程度改善人体热舒适性,但是这种改善是有限制的,空气温度过高、风速太大或长时间吹风都可能会导致人体不舒适。A physiological and psychological experiment was conducted in summer,2008 to ascertain the effect of air flow on human thermal comfort in hot summer.The statistics analysis shows that air flow makes physiological index and thermal sensation an obvious drop tendency,which is correlated to the air temperature of indoor environment.The lower the air temperature is,the greater the physiological index and the thermal comfort drop.But when the temperature is up to about 34℃,the air flow almost does not make any change to physiological index while the human sensation is still improved.These results indicate that air flow can improve human thermal comfort to some extent,but the improvement has limits.Higher air temperature,strong wind and long time exposure to wind can lead to uncomfortableness.
