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。
Subway station public areas of today’s air-conditioning design, the main return air way to send a single back and both sides to send the middle back to two. According to different civil structures using different ways. However, due to the relatively large space, the improper return air method may result in poor air flow organization. In this paper, taking a metro station and hall as an example, this paper uses CFD method to simulate and compare different modes of returning air in the same station and hall, and evaluates the effect of the two methods in all aspects, providing reference for further research and engineering design of metro station.
