Development of low sound perception compressors
Project Description: With the market increasingly competitive and with stricter regulations, compressors have been the product of intense research with the objective of reducing their sound emission and vibratory energy. This project acts in this direction through the following activities: analysis of mechanisms for generating and propagating vibratory energy in compressors; refrigerator noise analysis generated by compressors excites; development of tools for sound quality analysis of compressor-cooler system; development and application of optimization tools in compressors.
Coordinator/Participants: Prof. Arcanjo Lenzi (coordinator); Prof. Erasmo Felipe Vergara Miranda (collaborator); Dr. Olavo M. Silva (collaborator).
Partners: NIDEC/Embraco; Santa Catarina Teaching and Engineering Foundation (Fundação de Ensino e Engenharia de Santa Catarina – FEESC)
