以重庆某火车站地下车库为例,应用PHOENICS软件对车库的通风系统进行数值模拟,并针对初步设计方案的不足提出了改进措施。模拟结果表明:该火车站地下车库的通风换气次数宜为10次/h;相较于传统地下车库中所应用的集中式送风口形式,采用均匀布置的送风口方式可以有效改善火车站地下出租车库内的通风环境。
以重慶某火車站地下車庫為例,應用PHOENICS軟件對車庫的通風繫統進行數值模擬,併針對初步設計方案的不足提齣瞭改進措施。模擬結果錶明:該火車站地下車庫的通風換氣次數宜為10次/h;相較于傳統地下車庫中所應用的集中式送風口形式,採用均勻佈置的送風口方式可以有效改善火車站地下齣租車庫內的通風環境。

With an example of a underground garage of a railway station in Chongqing, the ventilation system of the garage are simulated by the PHOENICS software, and then improvement measures are proposed aiming at the shortcomings of the preliminary design scheme. The results of numerical simulation indicate that the minimum air change rate is appropriately 10 times per hour for this garage. Furthermore, compared to the centralized air supply outlet in traditional underground garage, adopting uniform air supply outlet mode can effectively improve the ventilation environment of underground taxi garage in railway station.
