【中文摘要】 地铁站厅公共区现今的空调设计,送回风方式主要有单送单回和两侧送中间回两种。根据不同的土建结构采用不同的方式。但由于空间比较大,送回风方式不合适可能会导致气流组织不良。本文以某地铁站厅为例,利用CFD方法,模拟和对比同一站厅不同送回风方式,并从各方面评价两种方式的效果,为地铁站气流组织的进一步研究和工程设计提供参考。 【英文摘要】 Now there are two different modes of air distribution in air conditioning systems used in subway station: one of which discharging air from one side of the station hall and returning air into the another side of the hall, and the other discharging air from both sides of the hall and returning air into the middle of the hall. Different modes of air distribution are always adopted in different building structures. However, since the space of a subway station is large the modes of air distribution are always inappropriate which leads to bad air distribution. In this paper, we take a subway station for instance to simulate and compare the air stream characteristics of two different modes of air distribution by Computation Fluid Dynamics (CFD) method, and evaluate the effects of two different modes on all hands. It will provide a reference for further research and design later. 【中文关键词】 地铁站; 送回风方式; 气流组织; 模拟 【英文关键词】 subway station; mode of air distribution; air stream characteristic; simulation
