对地铁隧道通风系统从排热风机运行策略和中间风井取舍进行节能研究。以成都某地铁线路的设计方案为模型，基于VBA编程优化后的SES程序对不同运营时期、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，得到车站隧道排热风机各种工况下的节能运行策略及效果。计算结果表明，车站活塞井在初期、近期和远期主要表现为引进新风，远期进风量远大于排风量，环线线路具有特殊性。同时分析了中间风井对附近活塞风井空气流动影响和对隧道内壁面与空气温度的影响，并以温度为评价指标，从地铁环控通风系统的节能角度分析了中间风井的利与弊，得出可以取消中间风井的结论，为实际设计提供了理论依据。

Study was conducted on the energy-saving operational strategies of subway ventilation systems and the a-doption of the middle vent shaft. The study model originated from the primary design documents of one line of Chengdu metro. Through simulating,the metro thermal environment hourly using VBA optimized SES program in a variety of air flow conditions at different operational periods, the energy-saving operational strategies were studied. The amount of the air input of the piston vent shafts is equal to the air output at the initial and recent operational stages, and the amount is larger at the future operational stage under the energy-saving operation plan. And particu-larities of the loop line were studied. The influences of the middle vent shaft on the nearby piston vent shaft, the wall surface temperature and the air temperature in the tunnel were analyzed. Finally,taking temperature as the es-timated index, the advantages and disadvantages of the middle vent shaft were analyzed.
