负离子技术对地铁站环境改善效果的研究
Study on improving effects of negative ion technique on environment in an underground railway station
摘要：
在三个典型空调运行季节对上海徐家汇地铁站环境使用负离子技术前后人流高峰期的污染物与人流量进行了监测，研究了负离子技术对地铁站台、站厅环境的改善效果。着重分析了负离子技术的特性，评价了其与人流量、气流分布相关的净化效应，探讨了负离子在地铁站台、站厅应用的可行性。

Abstract：
Monitors the change of the contamination concentration and the amount of passengers in peak hours before and after using the technique in Xujiahui underground railway station in three typical air conditioning seasons. Explores the effects of environment improvement in platform and station hall of the station. Emphatically analyses the characteristics of this technique, evaluates its cleaning effect in response to passenger flow and air distribution, and discusses the practicability of applying negative ion technique to such locations.
Keywords:negative ion, underground railway station, passenger flow, inspirable particle concentration, airborne bacterial concentration
