피치각 조정형 송풍-역풍 겸용 축류팬에서 배연용 피치각 선정을 위한 실험적 연구
An Experimental Study on Selection Pitch Angle on backward flow of an Axial Fan with Adjustable Pitch Angle Blades
초록
In this study, the experimental study has carried out to select pitch angle on the backward flow in an axial fan that has adjustable pitch blades. With the change of pitch angle of axial fan with adjustable blade, air flow rate, pressure and air flow direction can be changed. Because of this merit, adjustable axial fan can be used in the backward flow. For the selection of the backward flow pitch angle, fan performance test method is selected by KS B 6311. Dynamic pressure, static pressure, electric current and voltage are measured in each pitch angles of axial fan that are
