基于地铁环境模拟的地铁通风系统设计

Discussion about the Design of Subway Ventilation System based on Simulation of Subway Environment

地铁运输比路面交通方式更具可持续性,通风系统作为地铁系统中的重要组成部分,设计人员应了解环境对其建设,维护和运营的影响,应将通风系统设计与系统整体热工性能相结合,从而实现更高效、持续的通风功能。本文通过仿真计算地铁通风系统设计前期的各个参数影响,明确各参数各自的最佳工作数值范围,并在设计阶段将各参数最优值进行优化结合,从而最大程度实现既经济又可持续的工程设计方案。

Subway transportation is more sustainable than road transportation.As ventilation system is an important part of the subway system,designers should understand the impact of the environment on its construction,maintenance and operation.The ventilation system design should be related to the overall thermal performance of the subway system for more efficient and continuous ventilation.By computer simulation,this paper introduces the influence of various parameters in the early stage of subway ventilation system design,and clarifies the optimal working value range of each parameter,with optimizing the optimal values of each parameter in the design stage to make an economical and sustainable engineering design.
