压机舱涡流噪声分析与优化研究
Analysis and optimization of eddy current noise in the press chamber
摘要
Abstract
In response to the eddy current noise problem in a certain type of horizontal refrigeration cabinet compressor chamber,analyzes the composition of the compressor chamber sound source,the mechanism of eddy current noise generation,and fluid and acoustic simulation to obtain the source of eddy current noise in the horizontal refrigeration cabinet compressor chamber,and further improves and optimizes the overall machine noise.The results indicate that:(1)The vortex noise of the horizontal freezer is caused by the axial flow fan in the compressor chamber,and amplified through the compressor chamber.(2)Eddy current noise is related to the effective ventilation area of the inlet and outlet of the compressor chamber.Experiments have shown that by increasing the inlet by 30％and reducing the outlet area by 10％,the overall noise is reduced by 3.0 dB(A).关键词
