摘要
应用数字实验方法 ,通过调节分支风阻 ,研究它对通风系统的影响。研究结果表明 ,当一些分支风路的风阻调到接近完全隔断风流的极大值时 ,网络分析结果仍然正常 ,不影响迭代技术 ,同样也说明了分支风阻预先输入的可行性。各分支风阻的变化对通风系统的影响程度是不一样的 ,这由分支在通风网络中的位置决定。同时分析了通风系统中两风机的相互影响的情况。
The influence of adjusting branch resistance on the ventilation system is studied based on the digital experiment in computer. The study shows that results from network analysis are still normal with the iteration technology not to be impacted, while resistance of some branches in the network is increased near to a maximum value to cut off wind flow. The feasibility of imputing the branch resistance in advance is proved. Change on the resistance of each branch has different effect on the ventilation system, which depends on the location of each branch in the ventilation system. Also, some studies have been done on the international effects between two fans in ventilation system.
