新一代“零换乘”火车站由于空间高大、通透性要求高和各种空间的连通性强等特点,导致大量的无组织渗风,对空调系统的冷热负荷、主站房室内大空间气流组织及热舒适性研究有着巨大的影响。本文对南京南火车站的无组织渗风进行了研究:设计阶段通过模拟手段预测无组织渗透风量的大小,对空调系统的冷热负荷计算提供参考;实际运行阶段,通过实地测试验证模拟结果,提供宝贵的工程经验,为后续的大型铁路站房的渗透风研究提供依据。
The new generation of “zero transfer ” train station due to space, high permeability and a variety of spatial connectivity and other characteristics, resulting in a large number of unorganized seepage, the air conditioning system cooling load, the main station room Large indoor air flow organization and thermal comfort has a huge impact. In this paper, the unorganized seepage of Nanjing South Railway Station was studied: In the design stage, the size of the unorganized seepage air flow was predicted by simulation and the reference was provided for the calculation of cooling and heating load of air conditioning system. In the actual operation stage, Provide valuable engineering experience, and provide the basis for the follow-up study on the seepage wind of large railway station buildings.
