上海轨道交通车站设备用房通风空调系统问题的调查研究

Investigation of the Air Conditioning and Ventilation System at Shanghai Metro Stations

近年来,上海轨道交通地下车站的部分通信和信号机房频繁出现温度过高现象,部分供电机房出现风管凝露滴水情况,引起设备故障。考虑到上海轨道交通各条线路车站设备管理用房通风空调系统之间存在不同的设计方式,而影响通风空调系统末端温度的因素较多,基于现场调查及测试,对地铁车站设备用房通风空调系统中存在的问题进行分析,提出了一些改善措施,指出改善设备用房末端空调的效果,需要设计、建设、运营三方共同努力。

Recently, higher temperature is frequently observed in some communication and signal rooms at Shanghai metro underground stations, the air duct condensation dropping has even caused operational failures in power supply. Since the design patterns of ventilation and air conditioning system are quite different at Shanghai metro stations, many factors may affect the end temperature of the system. By analyzing the problems existed in ventilation and air conditioning systems for subway station equipment rooms based on field investigation, a number of improve- ment measures has been taken, the joint efforts of design, construction and operation units are stressed.
