东北严寒地区地铁通风系统方案优化研究
Optimization measures for underground railway ventilation system in the severe cold Northeast region
摘要：
给出了东北严寒地区地铁通风系统活塞风道、风机及风井配置，运行模式等方面的优化措施；分析了不同季节、不同工况下通风设备的能耗和工程造价；并对优化方案进行了计算机模拟验证。结果表明，采用有针对性的优化措施既可以满足冬季乘客候车舒适度的要求，又可以较大幅度地减少工程初投资和运行费用。

Abstract：
Presents the optimization measures for the piston air shaft, distribution of air blower and ventilating shaft and operation model, analyses the energy consumption and construction cost in different seasons and different operation conditions, and carries out computer simulation and validation on the optimization schemes. The result shows that adopting the specific optimization measures can keep the passengers’ comfort when waiting in winter and substantially reduce the initial investment and operation costs.
