随着我国城市轨道交通的迅速发展,站台屏蔽门得到了广泛应用。地铁车站在采用屏蔽门后,如何考虑屏蔽门漏风量对车站空调负荷的影响成为了广大设计人员需要考虑的问题。本文通过对屏蔽门漏风量的各种影响因素进行分析,提出了使用网络法来估算屏蔽门漏风量的方法,并通过与现场测试结果的对比验证了该方法的准确性。与CFD计算方法相比,该方法计算过程简便,可用于设计阶段屏蔽门漏风量的估算。在此基础上,分析了屏蔽门漏风量对地铁车站空调系统负荷的影响。
With the rapid development of urban rail transit in our country, platform screen doors have been widely used. Subway station in the use of PSD, how to consider the impact of PSD leakage on the station air conditioning load has become the majority of designers need to consider the issue. In this paper, we analyzed the various influencing factors of air leakage in screen door and proposed a method of estimating air leakage of screen door by using network method. The accuracy of this method is verified by comparison with field test results. Compared with the CFD calculation method, this method is simple and can be used to estimate the amount of air leakage in the screen door during the design stage. Based on this, the influence of air leakage of screen door on the air conditioning system load of metro station is analyzed.
