摘要
提出了一种计算风管漏风及阻力损失的逐段递推计算法。该法既考虑了风压对漏风的影响,又考虑了漏风对风流阻力的影响。其结果比其它方法更精确、更符合实际。同时,还对局扇的串联运行进行了理论分析,得出了风机间隔串联时避免风管内产生循环漏风的风机间隔距离以及风机集中串联时所需风机台数的计算式。
A method for designing the auxiliary ventilation system for long
drivages with multiple fans spaced in series in long duels is proposed based on the criterion that no recirculation takes place between the air flowing in the duct line and the surrounding air, A recurrence method is also given to calculat the leakage and the resistance lose of the duct taking into account of the relationship among the pressure, resistance and the leakage of the duct. The calculating results show that the present method is belter than the other methods.
