【摘要】： 随着现代化城市发展的需要,随着人口和经济的迅速增长,世界各主要城市要求地铁系统以更快的速度发展。同时,地铁所产生的热量大幅增加,需要地铁环控系统排除大量的地铁废热,因此,地铁环控系统的运行能耗是地铁总能耗的重要组成部分。地铁屏蔽门系统的优点是减少地铁车站的热负荷,改善车站站台的候车环境,并且减小车站内环控系统的机房面积,降低地铁环控系统的运营费用。随着城市整体功能的提升,屏蔽门越来越多的被应用于世界各地的地铁中,不仅在夏季空调期较长的南方地区普遍采用站台屏蔽门,在空调期较短的北方地区的城市地铁中,也在逐渐推广采用站台屏蔽门。地铁风井风亭占用地铁建筑和地面空间,尤其是在城市中心区非常困难;隧道活塞风对于地铁隧道热环境具有重要的影响,活塞风井的设置在屏蔽门系统中是必不可少的。因此,研究地铁热环境,研究活塞风井风亭的设置数量,分析地铁环控系统运行情况,对地铁节约用地和节能运行具有重要意义。经过模拟计算研究,得出可以在北方地区城市地铁设置屏蔽门系统地下车站隧道通风系统的设计方案中设置单活塞风井方案的重要结论,并在津滨轻轨西段工程及天津地铁2、3号线工程中加以应用,从而节省地铁造价、节约风亭用地。现场测量是进行地铁热环境研究的一种有效途径。本课题以深圳地铁1号线会展中心岛式车站的隧道通风系统为研究对象,通过对地铁隧道内选定的测试断面的风速和温度进行现场测量,分析隧道活塞风的运动特性,并且对比在活塞风井全部开启和开启单活塞风井情况两种工况条件下风速和温度的变化趋势,从而为北方地铁屏蔽门系统的应用进行合理设计,分析评价运行情况,优化运行管理提供参考建议,并且为地铁环控系统的进一步模拟研究提供必要的基础数据和实验验证。
[Abstract]:With the development of modern cities and the rapid growth of population and economy, the major cities in the world require the subway system to develop at a faster rate. At the same time, the heat generated by the subway has increased substantially. It is necessary to remove a large amount of subway waste heat from subway environmental control system. Therefore, the operating energy consumption of subway environmental control system is an important part of the total energy consumption of subway. The advantage of subway shield door system is to reduce the heat load of subway station. Improve the waiting environment of the station platform, and reduce the area of the computer room of the station environmental control system and reduce the operating cost of the subway environmental control system. With the improvement of the overall function of the city, the shielded doors are more and more used in the subway all over the world. Not only the platform shield door is widely used in the southern area where the air conditioning period is longer in summer, but also the platform shield door is being popularized in the city subway in the northern area where the air conditioning period is short. The subway wind shaft pavilion occupies the subway building and ground space, especially in the center of the city, and the tunnel piston wind has an important influence on the thermal environment of the subway tunnel. The installation of piston air well is essential in the shield door system. Therefore, it is necessary to study the thermal environment of the subway, study the number of the piston air well wind booth, and analyze the operation of the subway environmental control system. It is of great significance to save land and save energy. Through simulation and calculation, it is concluded that a single piston air shaft can be set up in the design scheme of tunnel ventilation system of underground station in urban subway in northern area. It has been applied in the west section of Jinbin Light Rail and Tianjin Metro Line 2 and 3 so as to save subway cost and Fengting land. On-site measurement is an effective way to study the thermal environment of subway. This paper takes the ventilation system of the island station of Shenzhen Metro Line 1 as the research object. Through the field measurement of the wind speed and temperature of the selected test section in the subway tunnel, the motion characteristics of the piston wind in the tunnel are analyzed. And contrasts the variation trend of wind speed and temperature under two working conditions: the piston air well is all open and the single piston air well is opened, so that the reasonable design for the application of the shield door system of the northern subway is carried out, and the operation situation is analyzed and evaluated. The optimal operation management provides reference suggestions and provides the necessary basic data and experimental verification for the further simulation research of metro environmental control system.
