摘要
通过分析试验研究,阐述带扩散筒/塔和消声器的对旋式风机的效率比YB2F(JBT)系列低50%左右。指出我国盲目推广对旋式风机的损失,同时探讨了"双85"问题和局部通风避免采用大功率风机的方法,以便达到节能减排的目的。
By analyzing and researching, it is clarified that the efficiency of the counter - rotating fan with dif- fuser tube/tower and mufiler is 50% lower than YB2F（JBT） series. The loss of using counter - rotating fan is given. The “double 85” and the way of avoiding adopting high-power fan in local ventilation are also discussed. The aim is to save energy and to reduce emission.
