摘要
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。
The paper first summarized three major differences in load simulation of the air-conditioning and ventilation system between the subway station and a common public building. Due to these differences, it simulated the influences of the penetrative air through platform doors, the piston wind in the tunnel and the thermal environment in the tunnel using CFD and STESS models. The results were used as the inputs of the load simulation. Then a DeST model in consideration of underground envelope heat transfer was built, appropriate indoor air control parameters were set, and the all-year hourly load was simulated. The results became the basis of system design and equipment selection： Energy-saving recommendations were provided, too.
