Abstract

ARRANJO DE RESSONADORES EM FILTRO ACúSTICO PARA COMPRESSOR DE REFRIGERAçãO A invenção refere-se a um arranjo de ressonadores em filtro acústico para compressor de refrigeração tendo uma carcaça (1), no interior da qual é montado um filtro acústico compreendendo um corpo oco (10) definindo pelo menos uma câmara abafadora (13), que carrega um conduto de entrada de gás (20) e um conduto de saída de gás (30), cada um apresentando um respectivo comprimento e tendo uma respectiva espessura de parede, sendo que pelo menos um dos condutos de entrada de gás e de saída de gás (20,30) carrega, estendendo-se ao longo de pelo menos parte de seu comprimento, uma respectiva pluralidade de condutos ressonadores (40), tipo tubo, cada conduto ressonador (40) apresentando um primeiro extremo (41) aberto para o interior do respectivo conduto de gás (20, 30) e um segundo extremo (42), oposto e afastado do primeiro extremo (41), cada dito conduto ressonador (40) sendo dimensionado para apresentar um determinado comprimento e um determinado diâmetro, calculados de modo a definirem uma certa impedância reativa e uma certa impedância dissipativa ao filtro acústico, para uma determinada faixa de freqüências.
