Abstract

"SISTEMA DE VOLUME DE AR VARIáVEL (VAV) DE ALTO RENDIMENTO COM CONTROLE DE VENTILAçãO ZONAL". A invenção refere-se a um sistema de ventilação e condicionamento de ar que utiliza um primeiro sistema de volume de ar variável para resfriar e desumidificar ar fresco externo e fornecê-lo através de um primeiro duto para uma caixa de mistura localizada a jusante. O sistema ainda utiliza um segundo sistema de volume de ar variável para adicionalmente resfriar e desumidificar ar reciclado e fornecê-lo através de um segundo duto para a caixa de mistura onde o ar fresco e reciclado são capazes de misturar antes de ventilar para uma sala ou escritório. O sistema utiliza um sensor de dióxido de carbono e um sensor de temperatura para prover sinais de retorno para um sistema de controle, o qual por sua vez regula as velocidades dos ventiladores e as aberturas dos registros de modo a prover um ótimo resfriamento e ventilação e conservar energia quando as necessidades de resfriamento e de ventilação são baixas.
