摘 要 ：为了研究鄂尔多斯火车站自然通风对候车厅和集散厅舒适性的影响，在当地夏季气候条件下，应用零方程湍流模型，对室外风条件和通风窗形式影响高大空间连通体热环境进行了模拟和分析。研究表明，合理利用室外风向和风速以及通风窗开启角度能够改善室内的热环境，既提高了舒适性，又达到了节能的效果。 关键词 ： 鄂尔多斯火车站 自然通风 室外风 热舒适性 Research On Natural Ventilation Application Of Large Space Building In Ordos Railway Station Abstract: In order to investigating the effects of the natural ventilation in Ordos Railway Station on the thermal comfort inside the Waiting Room and Distributed Hall, the effect of the outdoor wind and hopper windows type on thermal environments in the combined large space building was simulated an analyzed using the Zero Equation Model under the summer climates in situ. The study indicated the reasonable application of outdoor wind direction and velocity as well as hopper windows opening angle can improve the indoor thermal environment ,which can enhance not only the comfort but also the energy-saving effect.
