摘要
测试了上海地铁车站内活塞风的情况,分析了所得的数据,结果表明,活塞风对车站内的气流组织产生了巨大影响,列车进站时,活塞风绝大部分进入站台,活塞风竖井基本不 起作用;列车出站时,从室外吸入的空气会使站厅层内门厅处的温度瞬间升高(夏季)或降低 (冬季)4～6℃;过渡季节可以利用活塞风竖井引入室外新风,减少能耗。
Tests the status of piston wind in a Shanghai underground railway station, analyses the data obtained, and concludes that piston wind affects air distribution in the station seriously. When a train comes, piston wind enters a station mostly and shafts do not work. When a train leaves, the temperature at the hallway increases (in summer) or decreases (in winter) by 4 to 6 ℃ due to the air brought into the station. In spring or autumn, energy can be saved by way of bringing outdoor air into stations through shafts.
