【摘要】：环控系统是地铁用电大户,国内外已经开始对环境控制系统的设备选型、设计、运行等诸多环节进行进一步节能优化研究,并找到了一些可行的节能途径和措施。不过目前,对车站空调系统节能的相关研究较多,对隧道通风系统节能的研究仍少。 成都地铁7号线全线采用了屏蔽门系统,致使隧道与车站站台完全分割开来,同时在车站隧道处设置了轨道排热系统,所有车站都采用单活塞通风的形式,即在车站的出站端设置一个活塞风井。本文以成都地铁7号线初步设计文件为依据,建立SES所需的地铁模型,研究以下问题： (1)结合SES对不同运营时期、不同风量工况下地铁环控系统进行逐时模拟,通过分析不同时期土壤蓄热、列车运行模式和客流量等变化因素的影响,研究车站隧道排热风机各种工况下的节能运行策略及效果。 (2)分析七号线上中间风井的取舍问题,并为实际设计提供理论依据。 本文得出的结论和成果如下： (1)地铁运营初期关闭排热风机,近期非高峰时段关闭排热风井,高峰时段推荐轨道排风量为20m3/s,远期分时段分风量开启排热风井,地铁隧道内温度满足规范要求,大量节省能耗。 (2)7号线为环线具有特殊性,气流一直在环线循环,只能通过风井与外界进行气流交换。车站活塞井排在排热风机全部开启情况下初期和近期和远期都表现为引进新风,节能运行方案下,初期和近期活塞风井进排风量相差不大,远期进风量大大于排风量。 (3)取消中间风井隧道温度略微变化,影响区域仅为中间风井所在区间和前后车站两边区域,其他隧道温度保持不变；除中间风井所在区间隧道流量略微增大和活塞风井流量增大外,其他流量基本不变。综合分析认为：该处中间风井可以取消。
[Abstract]:The environmental control system is a large power user of subway. It has begun to study the selection, design and operation of environmental control system equipment, and find some feasible ways and measures to save energy. However, there are more researches on energy saving of station air conditioning system and less on energy saving of tunnel ventilation system. The shield door system is used in the whole line of Chengdu Metro Line 7, which results in the complete separation of the tunnel from the platform of the station. At the same time, the track heat discharge system is installed at the station tunnel, and all stations adopt the form of single piston ventilation. That is, a piston air shaft is installed at the exit end of the station. Based on the preliminary design documents of Chengdu Metro Line 7, this paper establishes the subway model needed by SES, and studies the following problems: (1) combining with SES to simulate the subway environment control system in different operating periods and different air flow conditions, By analyzing the influence of soil heat storage, train operation mode and passenger flow in different periods, the energy saving operation strategy and effect of station tunnel exhaust heat turbine were studied. (2) analyzing the problem of choosing and choosing the middle air well on No.7 Line, and providing the theoretical basis for the practical design. The conclusions and results of this paper are as follows: (1) in the early stage of subway operation, the exhaust air turbine is closed, and in the near future off-peak period the exhaust air well is closed. The recommended rail exhaust air volume in the peak period is 20m3 / s, and the forward air flow rate is divided into two stages to open the exhaust air well. The temperature in the subway tunnel meets the requirements of the specification and saves energy consumption. (2) Line 7 has its own particularity, the air flow has been circulating in the loop line, and the air flow can only be exchanged with the outside world through the air well. The initial, short and long term performance of the piston well row in the station under the condition of all the hot air drains is the introduction of fresh air. Under the energy saving operation scheme, the inlet and exhaust air volume of the initial and recent piston air well is not different, and the forward air intake is larger than that of the exhaust air. (3) to cancel the slight variation of the tunnel temperature in the intermediate air well, the affected area is only the interval of the intermediate air well and the area on both sides of the front and rear stations, while the temperature of the other tunnels remains unchanged; Except for a slight increase in the tunnel flow rate and an increase in the piston air well flow rate in the interval of the intermediate air well, the other flow rates are basically unchanged. The comprehensive analysis shows that the middle air well can be cancelled.
