【摘要】: 隨著現(xiàn)代化城市發(fā)展的需要,隨著人口和經(jīng)濟(jì)的迅速增長,世界各主要城市要求地鐵系統(tǒng)以更快的速度發(fā)展。同時,地鐵所產(chǎn)生的熱量大幅增加,需要地鐵環(huán)控系統(tǒng)排除大量的地鐵廢熱,因此,地鐵環(huán)控系統(tǒng)的運行能耗是地鐵總能耗的重要組成部分。地鐵屏蔽門系統(tǒng)的優(yōu)點是減少地鐵車站的熱負(fù)荷,改善車站站臺的候車環(huán)境,并且減小車站內(nèi)環(huán)控系統(tǒng)的機房面積,降低地鐵環(huán)控系統(tǒng)的運營費用。隨著城市整體功能的提升,屏蔽門越來越多的被應(yīng)用于世界各地的地鐵中,不僅在夏季空調(diào)期較長的南方地區(qū)普遍采用站臺屏蔽門,在空調(diào)期較短的北方地區(qū)的城市地鐵中,也在逐漸推廣采用站臺屏蔽門。 地鐵風(fēng)井風(fēng)亭占用地鐵建筑和地面空間,尤其是在城市中心區(qū)非常困難;隧道活塞風(fēng)對于地鐵隧道熱環(huán)境具有重要的影響,活塞風(fēng)井的設(shè)置在屏蔽門系統(tǒng)中是必不可少的。因此,研究地鐵熱環(huán)境,研究活塞風(fēng)井風(fēng)亭的設(shè)置數(shù)量,分析地鐵環(huán)控系統(tǒng)運行情況,對地鐵節(jié)約用地和節(jié)能運行具有重要意義。 經(jīng)過模擬計算研究,得出可以在北方地區(qū)城市地鐵設(shè)置屏蔽門系統(tǒng)地下車站隧道通風(fēng)系統(tǒng)的設(shè)計方案中設(shè)置單活塞風(fēng)井方案的重要結(jié)論,并在津濱輕軌西段工程及天津地鐵2、3號線工程中加以應(yīng)用,從而節(jié)省地鐵造價、節(jié)約風(fēng)亭用地。 現(xiàn)場測量是進(jìn)行地鐵熱環(huán)境研究的一種有效途徑。本課題以深圳地鐵1號線會展中心島式車站的隧道通風(fēng)系統(tǒng)為研究對象,通過對地鐵隧道內(nèi)選定的測試斷面的風(fēng)速和溫度進(jìn)行現(xiàn)場測量,分析隧道活塞風(fēng)的運動特性,并且對比在活塞風(fēng)井全部開啟和開啟單活塞風(fēng)井情況兩種工況條件下風(fēng)速和溫度的變化趨勢,從而為北方地鐵屏蔽門系統(tǒng)的應(yīng)用進(jìn)行合理設(shè)計,分析評價運行情況,優(yōu)化運行管理提供參考建議,并且為地鐵環(huán)控系統(tǒng)的進(jìn)一步模擬研究提供必要的基礎(chǔ)數(shù)據(jù)和實驗驗證。
[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.
