Numerical Prediction of the Radiated Noise of Hermetic Compressors Under the Simultaneous Presence of Different Noise Sources

Abstract

The prediction of the acoustic radiation of the compressor shell is resulting from a numerical vibro-acoustic model, involving the description of the compressor pump structure, compressor gas cavity and compressor shell structure, through the use of the FEM and BEM techniques. The presence of refrigerant and lubricating oil in the compressor cavity were… (More)
