摘要
压缩机内置消声器已成为压缩机普遍的一种降噪结构,但如何才能设计出一个具有良好降噪效果的消声器,则是研究的一个方向。通过消声器的消声原理,对市场上常见的消声器结构特征,如不同腔型、出口位置、高度、直径、变截面、隔板等进行分析;并基于声学有限元方法,明确了各特征对消声器消声能力的影响情况。在此基础上对某款压缩机运用上述研究成果在噪声问题的解决中,将其用于对压缩机内置消声器的设计优化与对比验证,最终实现了在解决产品实际问题上,关注频段平均降噪4至5分贝的良好效果。研究结果对压缩机及空调系统的降噪应用有一定的参考价值。
Compressor built-in muffler has become a common compressor noise reduction structure,but how to design a good noise reduction effect muffler,is a direction of research.Through the muffler muffler principle,the common muffler structure characteristics in the market,such as different cavity type,outlet position,height,diameter,variable section,partition board and so on are analyzed;Based on the acoustic finite element method,the influence of each feature on the muffler’s ability is clarified.On this basis,the above research results are applied to a compressor to solve the noise problem,which is used in the design optimization and comparative verification of the compressor built-in muffler.Finally,in solving the actual problem of the product,the good effect of focusing on the average noise reduction of 4 to 5 decibels in frequency band is realized.The research results have certain reference value for the noise reduction application of compressor and air conditioning system.
