摘要(Abstract):

全封闭冰箱压缩机的噪声问题是目前的研究热点,本文介绍了全封闭冰箱压缩机噪声产生的机理,并回顾了全封闭压缩机噪声问题国内外的研究现状,总结了一些主流的降噪方法和技术,包括削弱机械噪声、改进壳体形状、减缓气流脉动以及优化消声器结构等内容,并且介绍了一些减振降噪研究的新方法和新技术。
Focusing on the noise in hermetic refrigerators compressor,the mechanism of noise in hermetic compressors has been introduced,the achievements in the research of compressors' noise at home and abroad in the previous years has been reviewed,and the main methods and techniques for noise reduction has been summarized.This paper includes the following contents: the way to reduce mechanical noise,optimize of the shell,decrease the gas pulsation,and improve the muffler.A few techniques developed in recent years are also introduced.
