机械排烟系统是中庭建筑中使用最为广泛的烟气管理系统之一。文章基于区域模型中庭机械排烟系统的数学模型 ,编制了相应的模拟程序 ,并与实体实验和模型实验进行了对比验证 ,证明了模拟程序的正确性。另外 ,文章还讨论了排烟风机启动时间与排烟过程的关系 ,指出启动风机的时间不同 ,其排烟效果有很大的差别。
Mechanical exhaust systems are among the most widely used flue gas management systems in atrium construction. Based on the mathematic model of the atrium mechanical smoke exhaust system in the regional model, the article has compiled the corresponding simulation program, and compared with the physical experiment and the model experiment to prove that the simulation program is correct. In addition, the paper also discusses the relationship between the starting time of the exhaust fan and the process of smoke exhaust, points out that the time of starting the fan is different, and the exhaust smoke effect is greatly different.
