AC Fan flow pattern Analyzing

Judging from the "AC Fan" flow pattern, as we all know, for the fans, the media flow is obvious a phenomenon, and centrifugal fans primarily by changing the direction of flow within the duct medium, but axial fans do not change the flow direction of the medium, which is why the amount of wind centrifugal fan Why obvious reasons. Air pressure and air volume flow fan compared to centrifugal fan air volume and pressure is relatively small, the centrifugal fan in our lives will be applied in air-conditioning equipment, can be said to range more widely, axial fans are mainly use in warehouses and workshops, we have to be judged in accordance with the environment when selecting fan.
