摘要
降低噪声一直是家用电器产品研发的重点和难点.通过对国内外现有滚动转子式压缩机各种排气阀、降噪措施及其降噪前后的噪声频谱图的分析和比较,设计和研制了一套新排气阀及环圆周消声气流道的组合,将可取得明显的降噪效果.
In the research and development of household appliances,reducing noise is always a focus and difficult point.Through analysis and comparison of different exhaust valves, methods of sound attenuation, and sound spectrograms of the rotary compressor, this paper provides an efficient new system combined with exhaust valves and sound-absorbing channels for sound attenuation.
