Abstract

ARRANJO CONSTRUTIVO DE FILTRO ACúSTICO PARA UM COMPRESSOR DE REFRIGERAçãO. Acoplado a um sistema de refrigeração contendo um gás refrigerante, dito filtro acústico (10) compreendendo um corpo oco (11) definindo pelo menos uma câmara abafadora (14, 15) que carrega um conduto de entrada de gás (20) e um conduto de saída de gás (30) , sendo que pelo menos uma das partes de conduto de entrada de gás (20), de conduto de saída de gás (30) e de corpo oco (11) carrega pelo menos um elemento poroso (50) absorvedor de ruído e em contato com o gás refrigerante no interior do corpo oco (11).CONSTRUCTIVE ACOUSTIC FILTER ARRANGEMENT FOR A REFRIGERATION COMPRESSOR. Coupled to a refrigeration system containing a refrigerant gas, said acoustic filter (10) comprising a hollow body (11) defining at least one muffler chamber (14, 15) carrying a gas inlet conduit (20) and a venting conduit. at least one of the gas inlet duct (20), gas outlet duct (30) and hollow body (11) portions carries at least one absorbing porous member (50) noise and in contact with the refrigerant gas inside the hollow body (11).
