本文首先总结了地铁站空调通风系统的负荷模拟计算与一般公共建筑相比主要有三点不同。针对这些不同,本文通过建立计算流体力学(CFD)场模型与STESS网络模型的方法,分别对屏蔽门渗透风、隧道活塞风、隧道热环境进行模拟计算与分析,获得了相应结果,并将此结果作为负荷模拟计算的输入;同时在考虑了地下围护传热的基础上建立地铁站DeST模型,设定了合适的计算参数,计算出地铁站全年逐时负荷,为设计计算和空调选型提供了有效设计依据和相关节能建议。
This paper first summarizes the subway station air conditioning and ventilation system load simulation compared with the general public buildings there are three main differences. In view of these differences, this article through the establishment of computational fluid dynamics (CFD) field model and STESS network model method, respectively, the screen door penetration air, tunnel piston wind, tunnel thermal environment simulation and analysis, obtained the corresponding results, and this The result is taken as the input of load simulation calculation. At the same time, the DeST model of subway station is established considering the heat transfer of underground envelope and the appropriate calculation parameters are set, and the hourly load of subway station is calculated. Type provides an effective basis for design and related energy-saving proposals.
