Noise reduction of commercial refrigeration systems: compressor approach.

Author(s) : SILVEIRA M., SEDLIAK J.

Summary

During the last years, noise in commercial refrigeration has became more and more important and many of commercial appliance manufacturers have been devoting more attention to reduce the noise of their systems, aiming to fulfill the increasing demanding customer's requirements. Nowadays it is almost impossible to reach a very good noise level of the refrigeration system without taking into consideration the compressor as an important source; either by the level of noise directly radiated, either by the interaction with the system, it must be considered one of the main sources of noise in commercial applications. This interaction with the system also occurs as a result of gas pulsation and vibration levels, since both excite the components that fix the compressor to the system. This paper presents the studies carried through during the development of a new family of commercial compressors. The work aims to identify, quantify and determine, through product and process sensitivity analyses, the generating sources of the noise, the ways of its transmission and the influence of the final irradiator in the compressor's total noise and vibration levels.
