摘要
针对目前传统的屏蔽门系统和安全门系统的不足,提出了一种新的多功能门环控系统。该系统在传统屏蔽门的上部或站台端部安装可开闭百叶风口,可以利用列车运行产生的活塞风对站台进行通风。分析了列车运行产生的活塞风量及多功能门开孔面积对活塞风进入和离开站台的影响,对开孔面积进行了优化,得出了节能且经济的开孔面积范围。分析比较了传统屏蔽门系统和多功能门系统变风量运行情况下的全年能耗情况,结果表明,利用活塞风的多功能门环控系统节能效果明显。
In view of the problems existing in the traditional screen door and safety door, a new multifunctional door system was proposed. The system ventilates the platform with piston wind through opening a slit on the top or both sides of the traditional screen door. By analyzing the airflow of piston wind during subway running and the effect of opening area of slit on piston wind, the optimal area range of the opening slit was given. Annual energy consttmption of environmental control system with new and old program for ventilating was also analyzed and compared in this paper. The results showed that the new environmental control system with multifunctional door has an obvious energy-saving effect.
