沈阳地铁运营线路环控系统对比分析

Comparative Analysis on the Environmental Control System of Shenyang Metro Operation Line

地铁在改善城市道路拥堵、解决人们出行问题中取得了显著的成效,具有无可比拟的优势,全国各大中城市都在争相实施地铁的建设。目前,沈阳已开通了4条地铁运营线路,极大地缓解了出行压力。设计合理的环控系统在地铁运营中发挥着重要的作用,不仅能够提高运营服务质量,也肩负着节能减排的重任。介绍了沈阳地铁运营各线路的环控系统制式,对地铁1、2、9、10号线在设备布置、气流组织以及运行模式上进行了对比,分析了各自在能耗和舒适性方面的不同特点,并建议对地铁通风设备进行优化布置,减少风机设备并联的台数,以提高系统运行的可靠性。

Subway has achieved remarkable results in improving urban road congestion and solving people’s travel problems,with incomparable advantages.All large and medium-sized cities in China are implementing the construction of subway.At present,four metro lines have been opened in Shenyang,which greatly eased the travel pressure.The reasonable design of the environmental control system plays an important role in the operation of the subway,which not only improves the quality of the operation service,but also shoulders the heavy responsibility of energy conservation and emission reduction.This paper introduces the environmental control system of Shenyang metro lines,compares the equipment layout,air distribution and operation mode of metro lines 1,2,9 and 10,analyzes their different characteristics in energy consumption and comfort,and proposes to optimize the layout of subway ventilation equipment and reduce the number of fans in parallel,so as to improve the reliability of system operation.
