Abstract

"PROCESSO PARA CONTROLAR A PRESSãO E SISTEMA DE CONTROLE PARA CONTROLAR A PRESSãO DE AR CONDICIONADO NO INTERIOR DE UM DUTO DE SUPRIMENTO DE UM SISTEMA DE VOLUME VARIáVEL DE AR". Um sistema controla a pressão na qual (ar) condicionado deve ser fornecido a uma ou mais zonas a serem aquecidas ou resfriadas por meio do ar condicionado. O sistema computa de forma ativa um ponto de ajuste para a pressão em uma localização em um sistema de dutos à montante de onde qualquer ar condicionado deve ser fornecido às zonas. O ponto de ajuste é computado como uma função dos estados de posição dos registros no interior do sistema de dutos, os quais regulam o fluxo do ar condicionado para as respectivas zonas. O ponto de ajuste computado de maneira ativa é comparado com uma pressão sensoreada no sistema de dutos para determinar se a pressão no sistema de dutos precisa ser modificada.
