Abstract

"SISTEMA PARA CONTROLE DE FLUXO DE AR EM REFRIGERADORES E FREEZERS". Compreendendo compartimento de refrigeração (10) ; um compartimento resfriador de ar (20) alojando um evaporador (21) e um ventilador (22); e um plenum distribuidor de ar (23), recebendo um fluxo de ar forçado do ventilador (22 ) e tendo uma parede anterior (24 ) provida de passagens de ar (25) através das quais o fluxo de ar forçado é alimentado ao interior do compartimento de refrigeração (10), sendo que pelo menos parte das passagens de ar (25) da parede anterior (24) do plenum distribuidor de ar (23) é operativamente associada a respectivos meios obturadores (40 ) seletivamente deslocáveis para diferentes posições operacionais nas quais mantêm as passagens de ar (25) com uma área livre dimensionada em função da intensidade de fluxo de ar forçado a ser alimentado ao compartimento de refrigeração (10).
