| 活塞风效应是影响地铁车站环控系统的重要因素之一，在过渡季节利用活塞风效应可有效降低地铁车站环控设备的能耗。提出了在车站站台端门安装单向风阀的假设，利用活塞风的抽吸效应，通过站台端门的单向风阀形成区域负压，从车站出入口引入室外新风。首先推导得到基于端门承压的引入新风量计算模型，再通过实测获得不同行车密度下各端门的承压特性，最后基于该模型计算得到引入新风量。结果表明：在列车运行过程中，进站端端门主要受正压影响，离站端端门主要受负压影响；单次列车通过离站端端门引入的新风量最高可达1 300 m3。研究可为在过渡季节利用活塞风效应实现地铁车站环控系统节能提供理论基础。 |

| The piston wind effect is a key factor influencing the environmental control system of subway stations. Leveraging this effect during transitional seasons can effectively reduce the energy consumption of such systems. This study proposes the installation of one-way dampers at the platform end doors, utilizing the suction effect of piston wind to create a negative pressure zone, thereby drawing outdoor fresh air through station entrances and exits. A theoretical model for calculating the induced fresh air volume based on the pressure at the end doors is first derived. Subsequently, the pressure characteristics at each end door under varying train operation densities are obtained through field measurements. Finally, the fresh air volume introduced by this method is determined using the proposed model. The results indicate that during train operation, the end door at the train entry side is predominantly subjected to positive pressure, while the door at the exit side experiences negative pressure. The maximum fresh air volume induced through the exit-side end door after a single train passage can reach up to 1300 m3. This study provides a theoretical basis for energy-saving operation of subway station environmental control systems during transitional seasons by exploiting the piston wind effect. |
