高层住宅排气道系统动力源的比较及其对系统的影响

对高层住宅排气道系统进行了模拟实测的研究，研究表明其结果与中低层住宅排气道系统的结论一致，动力源的集中位置与封闭面的距离越近，系统阻力损失越大，起始段静压升高越显著，但不成正比关系。动力源的布置位置越分散，其整体主管静压就会越小，反之，越大。在一定间距的情况下，动力源布置越均匀，系统阻力越小，气流越均匀。动力源对系统影响的比较与动力源的性能有着密切的关系。

The Comparison of the Power Source of High-rise Residential Exhaust System and the Influence on the System

The experimental study of the simulated high-rise residential exhaust system in the measured way shows that the results with lower residential exhaust system is consistent, the closer the distance of centralized location of power source with closed face,the more the system resistance loss and initial pressure rise will be ignificantly, but not with directly proportional relationship .The more dispersed the power sources are, the smaller the overall charge of static pressure will be, conversely, the more. In a certain spacing cases, the more uniform the power source arrangement is , the smaller the resistance of the system will be,and the more uniform flow there be. There is a close relationship between the impact on the system performance in comparison with the performance of power source.
