The Cavity Resonance and Noise Reduction of Hermetic Reciprocating Compressor

摘要

The noise resources and the transmission paths of hermetic reciprocating compressors are analyzed in this paper. Several ways to shift the cavity resonance frequency of the compressor by changing the shell cavity natural frequency are also summarized. A special method to reduce the acoustic noise of a compressor, flexible perforated panel with tube bundle, is presented.
