摘要
In order to analyze the influence of the air outlet louver on the noise generated by the outdoor set of a split-unit air conditioner, the flow field in the outdoor set is simulated with the CFD software STAR-CD. The relative turbulent intensities are computed and the influence of the shape and the steel wire diameter of the air outlet louver on the noise generated by the outdoor set is analyzed. The results of computation and experiment show that the circular shape of air outlet louver gives benefit of noise decrease. An air outlet louver with different diameters of steel wires is designed on the basis of analysis of the influence of the steel wire diameter of the air outlet louver on the noise. The computation and experiment validate that the air outlet louver with different diameters of steel wires can improve the aerodynamic performance and reduce the noise generated by the outdoor set.
