摘要:对于非屏蔽门地铁车站,从隧道进入站台的无组织气流对地铁车站通风空调系统的运行能耗有重要影响。本文基于STESS软件,对采用非屏蔽门系统的地铁车站的隧道与站台的空气交换量进行了模拟研究,分析了隧道长度、发车对数、双向列车到站时间间隔等因素对非屏蔽门系统隧道与站台的空气交换量的影响。根据模拟结果,给出了隧道与站台的空气交换量的估算公式,可用于地铁通风空调负荷计算及运行能耗分析。

Abstract: For bailout door subway stations, the unorganized air flow from the tunnel to the platform has an important impact on the operation energy consumption of the ventilation and air conditioning system of the subway station. Based on STESS software, this paper conducts a simulation study on the air exchange volume between the tunnel and the platform of the subway station with the bailout door system. The influence of factors such as the length of the tunnel, the train departure density, the arrival time interval between two-way trains, etc. on the air exchange volume between the tunnel and the platform of the subway station with the bailout door system is analysed, respectively. According to the simulation results, the estimation formula of the air exchange volume between the tunnel and the platform is given, which can be used for the calculation of the ventilation and air conditioning load of the subway and the analysis of the operation energy consumption.
