湿热地区人群夏季主动利用气流的研究(1):行为与动机

Airflow utilization in built environment in hot-humid area of China(1):Behaviors and motivations

气流是湿热地区人群改善夏季室内热环境的有效方式。通过对自然通风宿舍32名大学生的夏季现场测试与调研,获得了他们主动利用气流行为的变化特征,并就行为背后的动机加以分析,结果显示:门窗的开启兼顾热环境改善和通风换气,开启率随新有效温度缓慢线性增长;风扇的使用以改善热环境为主,使用率随新有效温度呈较好的S形关系变化,增长迅速而剧烈。研究结果对建筑自然通风和风扇设计及建筑热环境与能耗模拟有参考价值。

Airflow is an effective way for people in hot-humid area of China to improve their thermal environment in summer. Through the field survey on 32 college students in their naturally ventilated dormitories, obtains their behaviors to utilize airflow and analyses the behind motivations. The results show that with motivations of both thermal environment and air quality, openings of windows and doors grow linearly and slowly with new effective temperature, and with single motivation of thermal environment, frequencies of using fans increase rapidly and sharply with new effective temperature. The present study provides reference for the design of natural ventilation and electrical fans, and also the simulation of building thermal environment and building energy consumption.
