Hermetic comrepsor muffler design: tuning of mufflers for noise reduction

摘要

Designing a silent ocmpressor,without many trials is possible when independent muffler results are available that give the muffler filtering frequency and transmission loss.Simple hand calculations cna be done [1] and are generally used for a quick check.In this study,a discharge muffling system is studied and redesigned to widen the filtering frequency band for a low back pressure hermetic comrpessor generally used in domestic refrigerators.
