摘要(Abstract)：

针对地铁活塞风与空调送风气流耦合现象,并以上海某地铁站为原型搭建液体缩尺实验台,通过盐水模拟试验得出了耦合气流温度特性。模型试验反映了活塞风作用的整个过程,得出在此过程中空调送风口下方竖直方向上的温差波动达到3℃左右;距地面1.6m高处平面,在活塞风方向上距空调送风口约2.6m处温差波动只有0.5℃左右,故可认为在地铁活塞风作用下空调送风影响区域的大小为2.6m左右,在此区域外,温度几乎无波动,与活塞风温度基本接近。此结果由现场实测进行验证。
To research the piston wind and air-conditioning airflow coupling,according to the liquid bench which was built by chosen a subway station of Shanghai as prototype.Model experiments have a realistic simulation of the entire process of the train's movement,including coming,stop and leaving.Come to a Conclusion that the temperature fluctuations of vertical direction under air conditioning outlet is about 3℃.The level leaving ground about 1.6m,the temperature fluctuations along the piston wind direction and leaving air conditioning outlet about 2.5m is 1℃.In supply of Air Conditioning area,the size of zone that was influenced by subway piston wind is about 3m.Out of this region,the temperature is almost no fluctuation and the temperature was close to piston wind.The result verified by field measurement.
