以地铁车站公共区负荷为研究对象,在前人研究基础上继续完善地铁车站公共区负荷计算方法,用该负荷计算方法得到的数据作为输入参数,应用TRNSYS软件建立地铁车站公共区逐时负荷计算模型。以南方某屏蔽门地铁车站为例,用该站夏季某时间段的实测负荷数据对TRNSYS模型进行验证;并用该模型对负荷影响较大的因素做详细分析,挖掘该站的节能潜力,得到在关闭新风阀和提高车站控制温度时,该站公共区负荷可分别降低68%和42%。希望可以应用该方法为地铁车站公共区空调设计、运行和能耗管理提供一定指导。

[Abstract]
Taking the load of a public area in metro stations as the research object, we improved the calculation method for the load of public areas in metro stations on the basis of previous studies. The data obtained from the calculation method were used as the input parameter. We utilized TRNSYS to simulate the hourly cooling load of the public area of the metro station. The TRNSYS model was verified with an actual measurement result during summer of a metro station with the PSD in South China. We used the model to analyze the factors that have a significant influence on the load to tap the energy-saving potential of the station. When the fresh air valve was closed and the control temperature of the station was increased, the load in the public area of the station could be reduced by 68% and 42%, respectively. It is hoped that this research will provide guidance for metro HVAC system design, operation, and energy management.
