【摘要】 为研究气流在高温高湿工况下对湿热地区人群热湿反应的影响，选取18名出生并成长于湿热地区的大学生作为受试者，在高温(29℃、32℃、36℃)和高湿(50%、70%、90%)组合环境下，由受试者自主选择风速，获取受试者热湿心理反应。结果表明：高温高湿下，热感觉、热舒适、热可接受度出现分离。热不可接受比例与湿不可接受比例成正相关。使用气流可显著改善热感觉，但对热舒适、热可接受度的改善有限。在29℃、32℃工况下，相对湿度不大于70%时，随着空气温度的上升，受试者选择的风速增加；相对湿度为90%时，受试者选择的风速低于同温度、相对湿度70%时的风速。在29～36℃工况下，使用风扇可扩展热可接受度区间，对应10%热不可接受率的ET~*值由30.3℃提高至31.1℃;在29～36℃工况下，使用风扇会缩小湿可接受度区间，对应10%湿不可接受率的ET~*值由30.7℃下降至29.8℃。更多还原

【Abstract】 In order to study the influences of air movement on the thermal and humid responses of human under hot-humid conditions, eighteen healthy young people(nine males and nine females), who were born and raised in hot-humid areas of China, were recruited as subjects. Ten experimental conditions with high levels of air temperature(Ta)and relative humidity(RH)(23 ℃/90%, 29 ℃/50%, 29 ℃/70%, 29 ℃/90%, 32 ℃/50%, 32 ℃/70%, 32 ℃/90%, 36 ℃/50%, 36 ℃/70%), with one cool condition(23 ℃/90%), were tested. During the experiment, the subjects were able to control the fans themselves. Psychological responses were collected. The results indicate that under high levels of air temperature and relative humidity, the values of thermal sensation, thermal comfort, and thermal acceptability appeared to be separated. The values of thermal unacceptable ratio were positively related to the value of humid unacceptable ratio. Using air movement significantly improved thermal sensation, but the improvement in thermal comfort, especially thermal acceptability, was limited. At 29 ℃ and 32 ℃, when the relative humidity was below 70%, as the air temperature increased, the air speed selected by the subject increased; when the relative humidity was 90%, the air speed selected by the subject was lower than when the relative humidity was 70%at the same air temperature. From 29 ℃ to 36 ℃, using fans could expand the thermal acceptable range, the upper limit for people in hot-humid climates who engaged in sedentary activity and dressed in summer clothing(0.57 clo), was determined to be 31.1 ℃ in ET~* for the 90%acceptable range. From 29 ℃ to 36 ℃, using a fan would narrow the humidity acceptable range, and the upper limit was determined to be 29.8 ℃.更多还原
