Experimental study on the series critical point of cross flow and centrifugal fan

The critical point of series operation is a very important parameter of series operation of fans. In this study, on eight kinds of different operating conditions, critical points of the Cross Flow Fan and the Centrifugal Fan series operation were examined and measured and series operation critical curves of them were drawn. It offers theoretical evidence for series operation of the Cross Flow Fan and the Centrifugal Fan.
