| Abstract: | By experiment analysis of two existing kinds of muffler of rotary compressor, the actual effects and frequency characteristics of mufflers and muffling amount and distance to allowance of mufflers within frequencies have been got,which are important factors to design new muffler. Based on the experiment analysis of the compressor, a method of four pole network is used to analyze acoustic characteristics of the vested mufflers. Based on the analysis of acoustic characteristic of existing mufflers, a new two expansion chamber muffler is developed and designed, and the acoustic characteristics are analyzed. The noises of the compressors with the new muffler are reduced in 3 dB, and there is no power loss. |
