Abstract

"SISTEMA DE CONTROLE, E, PROCESSO PARA CONTROLARA PROVISãO DE áGUA CONDICIONADA A UMA PLURALIDADEDE TROCADORES DE CALOR". Um sistema para controlar oenvio de água aquecida ou resfriada para uma pluralidade detrocadores de calor inclui um controlador do sistema que coletainformação das correntes e futuras demandas de aquecimento ouresfriamento de uma pluralidade de controladores de zonaassociada a uma pluralidade de trocadores de calor. O controladordo sistema é operacional para prover água resfriada ou aquecidapara os trocadores de calor ainda que as demandas correntes deaquecimento ou resfriamento possam não é suficientes parasolicitar a provisão de água aquecida ou resfriada para ostrocadores de calor. O controlador do sistema executa isto pelaanálise das demandas correntes para aquecimento ou resfriamentoem combinação com demandas futuras para aquecimento ouresfriamento para determinar se há qualquer combinação dedemandas de aquecimento ou resfriamento corrente e futura queexcedam um nivel ou número mínimo de demandas que exceda onúmero ou nível mínimo de demandas necessário para autorizaraquecimento ou resfriamento. Um tempo de início para a provisãode água aquecida ou resfriada é , em seguida, determinado pelocontrolador do sistema no caso de haver qualquer combinação dedemandas de aquecimento ou resfriamento correntes e futuras queexcedam o nível ou número mínimo de demandas necessário paraautorizar um aquecimento ou resfriamento. O controlador dosistema também é operacional para implementar uma mudançaentre o envio de água condicionada em um sentido, como, porexemplo, resfriamento. A mudança implementada inclui, depreferência, verificar a temperatura da água retornando para afonte de aquecimento e fonte de resfriamento de água, bem como,definir um período de tempo de mudança que tem que ocorrer nocaso da temperatura da água na linha de retorno não estar dentrode uma faixa predefinida.
