基于实测数据浅析西安地铁站空调运行参数*
Air conditioning operational parameters in Xi’an underground railway station based on measured data
摘要：
利用西安地铁2号线冬、夏季室内外温湿度实测数据，通过计算相对热指标（RWI）与热损失率（HDR）等暂时热舒适指标来评价地铁站内乘客的热舒适状况，分析了乘客由室外进入地下双层岛式车站站厅和站台层过程中的热舒适变化特点。结果显示：夏季实测地铁站内空调温湿度数据基本满足人体热舒适要求，但乘客在由室外进入站厅层、再进入站台层的过程中RWI值变化较大，可能造成乘客的热不适，建议适当提高地铁站内空调运行温度来实现地铁站环控系统的节能运行；冬季乘客基本感觉热舒适。
Abstract：
Evaluates thermal comfort change of the passengers with the application of dynamic thermal comfort indexes such as relative warmth index (RWI) and heat deficit rate (HDR) based on the measured data of indoor and outdoor temperature and humidity of Xian Metro Line 2 in winter and summer. Analyses the variation characteristics of thermal comfort of passengers from outdoor to underground double-layer island station hall and platform floor. The results show that the measured air conditioning temperature and humidity data in the underground railway station basically meet the requirements of human thermal comfort in summer, but the RWI value changes greatly during the process of entering the station hall floor and then entering the platform floor, which may cause thermal discomfort of the passengers. So the operational temperature in the underground railway station should be properly increased, and at the same time the energy can be saved for the environment control system in summer. Passengers basically feel thermal comfort in winter.
