Subway Ventilation and Air Conditioning System Operating Mode of Study

Abstract

In this study, a regional standard practice in the construction of the subway stations and tunnels for the study, with the SES software, a mathematical model of the closed system, platform screen door (PSD) systems, hybrid air conditioning system (adjustable ventilated platform doors [1]) to run the program properly simulate the conditions. Analysis of annual energy consumption of each system to be; while the traditional mode of operation of the system to explore and optimization; ventilation and air conditioning system for the new subway rational design and operation and management of scientific data to provide valuable information..

Study on Dynamic Load of Air-Conditioning System in Subway Station Based on Hourly Passenger Flow

“…Among them, the personnel load would fluctuate greatly with the variation of passenger flow, and the fresh air load would be affected by the outdoor air enthalpy value, which belonged to the dynamic load. Therefore, from the perspective of reducing operation energy consumption and cost saving, the hour-by-hour calculation parameters of outdoor air could be calculated according to the variation law of short-term passenger flow in the future, and the dynamic load distribution could be obtained by summarizing various sub-loads [25]. The air supply parameters of the air-conditioning system of the subway station could be adjusted in time to alleviate the energy waste caused by the operation of the subway station to a certain extent.…”
