摘要
对活塞式制冷压缩机的吸排气腔声学特性进行了计算和分析,并对如何改进吸排气腔的结构来降低压缩机辐射噪声给出了建议,在改进压缩机排气消声腔结构设计基础上进行了压缩机辐射噪声对比实验,取得了一些降噪效果。
The acoustical properties of the suction and discharge chamber are calculated and analyzed, some ways to reduce the compressor noise through changing the structure of the suction or discharge chamber are presented. Based upon improving structural design of the suction or discharge cavity of the compressor, the comparison measurements of compressor noise are made. Sound attenuations to some extent are obtained .
