The Analysis of Tianjin Subway Environmental Control System

Abstract

The paper takes Tianjin subway as an example, and use the Subway Environment Simulation (SES) program to establish subway system with platform screen doors or different characteristics of two systems to carry out the simulate computation in summer, transition season and winter of the two systems; by analyzing the difference between two environment control modes, get the chart of the temperature distribution characteristic. The table result showed that it has more advantages using closed system than PSD system in Tianjin by using the primary invests and saving energy consumption.
