Comprehensive Technology Research Of Adjustable Ventilation Platform Doors System In Subway

With the rapid development of subway, subway operating power consumptionissues are also becoming more prominent. Ventilation and air conditioning systemsaccount for a large proportion in operational energy consumption. How to reduceoperational energy consumption of ventilation and air conditioning systems becomesa very important question.In subway system, security door system and platform screen door systems havebeen widely used. Integrated closed system plus safety door in the northern region hasbeen widely used. Platform screen door system in the southern region has been a largenumber of applications. Platform screen doors system in the summer can save theenergy consumption of air conditioning season, the safety doors system can save theenergy consumption of ventilation systems in the transition season. How to combinethe advantages of both, and applied to the project, is the starting point and focus ofthis study.The advantages and disadvantages of the safety door system and platform screendoor system are clear. We first create adjustable ventilation platform door systems tocombines the advantage of both sysetems. According to the climatic characteristics ofthe different regions of China respectively, ventilation and air conditioning system ofadjustable ventilation platform doors system for the warm regions, cold regions, verycold regions, were analyzed and researched. The ventilation and air conditioningsystem components, functional analysis and energy consumption were analyzed todifferent regions.On the basic analysis of three different parts of the adjustable ventilation platformdoor systems, the new system airflow and thermal environment were simulated. Itproved that the adjustable ventilation platform door systems meet the subway designspecifications and becomes more energy-efficient. We test the prototype of the newplatform screen doors to get air drag coefficient of the prototype, the amount of airleakage and other parameters. Thus proved the new platform screen doors can beachieved, and to meet the adjustable ventilation platform doors systemrequirements.The platform screen doors professional program was analyzed. Bycompared with the traditional platform screen door system, the implementation of thenew screen doors was introduced and the affect and precautions were researched. The article also analyzed the impact of adjustable ventilation platform doorssystem on FAS/BAS, Architecture and other professional. It indicates that the systemcan reduce the cost of the power supply system. It meets the functional premise whichdoes not expected to adversely impact of FAS/BAS. At the same time it can meet therequirements of archetcture on the ceiling and pipeline.This paper analyzes economicfunction of adjustable ventilation platform doors system. The initial investment,related civil engineering costs, energy consumption, operation and maintenance costsare anlyzed by divided into three areas.
