摘要:

实验研究了温度(262830 ℃)、相对湿度(60%80%)和不同活动量(动态及静坐)下,可控气流对16名中国受试者的热反应和气流偏好的影响。结果显示,静坐时提供可控气流,受试者可接受的温湿度可达30 ℃,60%,可控气流可在一定量活动后快速改善热舒适度,与ASHRAE 55标准对比可见,受试者舒适的温湿度范围和偏好风速高于标准规定。

Abstract:

Experiments on the effect of self-controlled air movement on thermal comfort and favorable air speed of 16 subjects from China exposed to the combined environment with different temperatures (26, 28, 30 ) and relative humidities (RH) (60% and 80%) combinations in hot-humid environments. Results show that air movement can maintain thermal comfort up to 30 and 60% RH at sedentary activity and restore comfort quickly after high metabolic rate activities, and subjects prefer higher air speed than ASHRAE 55 upper limit while remain comfortable beyond the comfort zone recommended by ASHRAE.
