地铁站乘客动态热舒适评价研究

Research on dynamic thermal comfort evaluation of passengers in underground railway station

分析了地铁站环境的特点和乘客出入地铁站时的热舒适变化特点。针对地铁站公共区域热环境特点,以南京某地铁站为研究对象,采用现场测试、问卷调查及动态热舒适评价模型RWI/HDR,对公共区域不同季节、不同评价单元的热舒适情况进行了分析和研究,得出了不同条件下乘客的热舒适度。研究发现,采用热感觉投票和相对热指标RWI相结合的方法能更为准确地评价地铁站热环境。最后结合南京地铁现有的环境与设备监控系统提出了车站温度动态控制模型。

Analyses the characteristics of underground railway station environment and the change of thermal comfort of passengers when they are in and out of the station. According to the features of public area in underground railway station, taking an underground railway station in Nanjing as a research object, analyses and studies the thermal comfort conditions in different seasons and different evaluation parts by field tests, questionnaires and dynamic thermal comfort evaluation model RWI/HDR. Obtains the thermal comfort of passengers in different conditions. The results show that the method combining thermal sensation vote with relative warmth index （RWI） can accurately evaluate the thermal environment of underground railway station. Presents a temperature-dynamic-control model combined with existing BAS of this underground railway station.
