摘　　要：电冰箱是现今生活中必不可少的家用电器,对电冰箱的节能降噪已经成为企业研发的重点。作为电冰箱的主要噪声源之一,研究抑制压缩机排气噪音的方法具有十分重要的现实意义。文章从流体网络模型思想出发,利用谐振滤波原理设计复合H型冰箱消音器,对压缩机排气压力脉动进行抑制。再通过噪音实验,验证了消音器对于冰箱整体噪音抑制的理论。The refrigerator is an essential household appliances in modern life, energy saving and noise reduction has become the focus of development in the refrigerator. As one of the main noise source of refrigerator, it has highly important practical significance to study the method of noise suppression for compressor. In this paper, from the perspective of fluid network model thought, using resonance filtering principle to design the H composite tpye muffler, in order to suppress the compressor exhaust pressure pulsation. And then through the experiment study, verify the noise suppression theory.
