湿热环境下空气流动对人体热舒适的影响（1）：不可控气流
Air movement and thermal comfort in hot-humid environments (1): Without occupant control
摘要：
实验研究了温度26，28，30 ℃，相对湿度60%，80%工况下，16名中国受试者对吊扇不可控（即固定）气流的热反应。结果表明：吊扇气流可显著提高热湿环境下的人体舒适度，受试者可接受的温湿度上限可达30 ℃，80%，偏好风速随温湿度上升而上升，最大至1.6 m/s，超出了ASHRAE 55标准给出的不可控气流适用范围。
Abstract：
Experiments on the thermal responses of 16 subjects from China exposed to the environment with fixed air movement from ceiling fans at three levels of temperature (26, 28, 30 ℃) and two levels of relative humidity(RH) (60% and 80%) by questionnaire. Results show that the air movement from fixed ceiling fan can markedly improve occupant comfort in hot-humid environment, and the thermal comfort can be maintained up to 30 ℃ and 80%, and the preferred air speed increases while air temperature and humid improves. The maximum preferred air speed is 1.6 m/s，much higher than the upper limit by ASHRAE Standard 55.
