碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 100 === In this study, a test facility of storm-resistant louver was designed and built in accordance with AMCA 500-L standard, a new pattern of storm-resistant louver based on simulation results in a prior work. The fixture was integrated with the blade of the new storm-resistant louver, and the limitations constrained by the extrusion process have been implemented in the design of the new louver shape. The experimental data of pressure drop agree with the numerical simulation in the prior work with less than 5% discrepancy. This proves that the integration of fixture and blade in this study is successful. The free area percentage new storm-resistant louver is 50%, which is 8% larger than a commercial available louver (42%), with the same pressure drop and the same rain resistant capability, which satisfy the requirement of penetration classification Class A of AMCA 500-L standard.
