Abstract

hoje em dia as pás de baixo ruído e especialmente as pás de superbaixo ruído para ventiladores axiais de grande diâmetro que são empregadas nas grandes máquinas de arrefecimento e instalações de arrefecimento são tão dispendiosas e estão exigindo muitos custos extras em outros equipamentos relacionados, que a redução da poluição sonora pode aumentar o custo total do aparelho de arrefecimento em até 35 %. esta invenção, provê uma nova tecnologia para tornar os ventiladores de baixo ruído capazes de transformar qualquer pá comum em um baixo ruído ou muito baixo ruído a um custo muito baixo, preservando a mesma alta eficiência e velocidade de ponta, como oposto a todas as outras pás de baixo ruído no status atual da técnica. como os ventiladores para os grandes aparelhos de arrefecimento são geralmente sua principal fonte de ruído, esta invenção irá oferecer a oportunidade de reduzir drasticamente a poluição sonora produzida por grandes máquinas de arrefecimento e instalações de arrefecimento.
