摘要(Abstract):

提出一种在毛细管上添加串联式抗性消声器的降噪方案,给出了该消声器的设计方法和结构参数。通过理论计算和声学仿真对消声器进行了消声性能的理论分析,结果表明消声器能有针对性的消除冰箱毛细管中产生的特定频率噪声,有利于降低冰箱整体噪声。
A noise reduction scheme of adding serial reactive muffler in capillary is proposed.And the design method and structure parameters are given.Through theoretical calculation and simulation,the performance of the muffler is analyzed.The muffler can be targeted to eliminate the specific frequency noise generated in the capillary,which helps to reduce the overall noise of the refrigerator.
