地铁活塞效应的节能综述研究

A Review on Energy Saving of Subway Piston Effect

随着地铁行业的蓬勃发展,利用活塞风降低车站能耗成为目前研究的热点之一。首先整理与活塞效应相关的国内外文献,研究活塞效应的形成机理和特性,分析活塞效应对地铁环控系统产生的影响,发现两者间潜在的节能关系。其次分别对隧道活塞风与车站活塞风的利用策略进行综述研究,这些策略主要与通风井的相关设计、列车的行驶、站台门的选择以及门帘的安装等有关,合理地采用这些策略可以为车站降低能耗。最后提出了活塞风的利用原则,在活塞风满足乘客需求的情况下应当优先利用活塞通风,应根据风量、温湿度、二氧化碳浓度以及颗粒物浓度等参数评价活塞风是否满足需求。

With the thriving development of the subway industry,reducing station energy consumption by utilizing piston wind has become one of the current research hotspots.Firstly,this paper collects and collates relevant domestic and international literature related to the piston effect,studies the formation mechanism and characteristics of the piston effect,analyzes its impact on subway environmental control systems,and discovers the potential energy⁃saving relationship between the two.Secondly,the utilization strategies of tunnel piston wind and station piston wind are reviewed and studied respectively in this paper.These strategies are mainly related to the design of the ventilation shaft,train operations,platform door selections,and the installation of door curtains.Reasonably adopting these strategies can effectively reduce station energy consumption.Finally,this paper puts forward the utilization principle of piston wind.When the piston wind meets passenger needs,the piston ventilation should be given priority.The evaluation of whether the piston wind meets requirements is mainly based on parameters,such as air volume,temperature and humidity,carbon dioxide concentration,and particle concentration.
