屏蔽门开启后，受活塞风及轨道排热系统影响，站台与隧道间产生压差形成空气交换，从而影响地铁车站内的空气流动。研究车站内空气流动规律，可为优化车站空调系统设计提供依据。对地铁屏蔽门开启时车站不同位置换气量进行测试，并应用 CFD软件模拟了车站及隧道内的空气流动。研究结果表明：屏蔽门开启时，室外空气经车站出入口流入站厅层，站厅层空气流入站台层，站台层空气经屏蔽门进入轨行区；车站空调运行状态对空气流动影响甚微。

In the opening of the sheilding gate,pressure gradient occurs between the platform and the tunnel due to piston wind and the heat-extracting system of the track,which results in an exchange of air and the ventilation at the station as a whole. A thorough study on the ventilation pattern at the station provides a solid foundation for the optimising of the air-conditioner design. The paper conducted research on the ventilation volume at various locations within the station and simulated the air exchange between the platform and the tunnel with the help of the CFD software. The results indicate that in the opening of the sheilding gate,air flows into the station hall from the entrance/exit,then to the platform,and then it runs through the gate and enters the train-running area. During this process,the air conditioner at the station plays a fairly insignificant part in the air exchange.
