摘要 通过问卷调查的形式,研究了20名处于不同大气压力环境中受试者的热感觉和风速期望随空气流速变化的情况,进而分析了不同大气压力环境中,空气流速对用风速期望进行评价的吹风感和人体平均热感觉(MTS)的影响.研究表明:低气压环境下人体对空气流速变化的感觉不如常压下敏感,人体在较高温度下对风速变化的感觉不如较低温度下敏感.在20-22℃时,低气压环境下微风速(〈0.2 m/s)范围内的风速变化对身着厚重衣物的受试者的热感觉影响十分微小. Through questionnaires,20 subjects are investigated about their thermal sensation and draft sensation under different pressure environments and different temperatures.The influence of air velocity on human mean thermal sensation(MTS) and draft sensation are analyzed under different air pressures.Then results show that human bodies are less sensitive to the air velocity variation under low-pressure environment and at high temperature.At 20~22 ℃,the effect of velocity changes on heavy-dressed subjects' thermal sensation in low air velocity(〈0.2 m/s) is slight under low-pressure.
