| 摘 要： | 笔者应用数字实验方法 ,通过调节分支阻力 ,研究它对通风系统的影响。研究结果表明 :当一些分支的阻力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 ;同样也说明了分支阻力预先输入的可行性 ;各分支阻力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 ;通过分析 ,给出了通风系统中两风机的相互影响的情况。

| Abstract: | By digital experiment,the effect of adjusting the branch resistance on ventilation system was studied. Results showed that when the resistance of a branch in a network was adjusted to a maximum value approaching to fully isolate the air flow,the analytical results of whole network were still at normal state and showed no impact on iteration technique. It also demonstrated that it was feasible to input the branch resistance in advance. Different branch showed different impact extents in ventilation system depending on relevant location in the system. The interaction between two fans in the ventilation system was also analyzed. |
