Abstract

CONTROLE PARA UM SISTEMA HVAC, MéTODO PARA OPERAR UM SISTEMA HVAC, E, SISTEMA HVAC Um controle para controlar um sistema HVAC multizonas, em que o equipamento de aquecimento ou resfriamento é operável em múltiplos estágios, leva em conta a demanda do sistema com o tempo durante a determinação de um estágio apropriado. Em particular, uma integral de tempo das demandas do sistema é utilizada juntamente com uma demanda do sistema corrente para determinar um estágio apropriado. Desta maneira, uma fraqueza na técnica anterior em permitir uma pequena diferença em longo prazo entre o ponto de ajuste desejado e a temperatura real nas várias zonas é abordado.
