NOISE REDUCTION OF HERMETIC COMPRESSOR BY IDENTIFICATION OF THE GAS CAVITY RESONANCE.

Author(s) : ALBRIZIO F.

Summary

A NEW RECIPROCATING COMPRESSOR FOR DOMESTIC APPLIANCES WITH HIGH EFFICIENCY, QUIET OPERATION, LIGHT WEIGHT AND SMALL SIZE HAS BEEN DEVELOPED. AN INTERESTING APPROACH TO REDUCE THE NOISE EMISSION AT 500 HERTZ (1/3 OCTAVE BAND) OCCURRED AMONG DIFFERENT KINDS OF INVESTIGATIONS ON THE OVERALL NOISE REDUCTION ACTIVITY. THE PAPER PRESENTS: THE IDENTIFICATION OF THE TRANSMISSION PATH, THE DESCRIPTION OF THE LAW DESCRIBING THE BEHAVIOUR OF THE 500 HERTZ FREQUENCY (FIRST WITH EXPERIMENTAL TESTS AND THEN WITH FINITE ELEMENT METHOD CALCULATIONS) AND FINALLY THE IMPLEMENTED TECHNICAL SOLUTIONS.
