Abstract

MODIFICACIONES EN UN SISTEMA DE CONTROL DEL FUNCIONAMIENTO DE MAQUINAS TERMODINAMICAS. CONSISTENTES EN QUE: LAS FUENTES DE CALENTAMIENTO Y/O ENFRIAMIENTO ESTAN DISPUESTAS DE MODO QUE OPEREN EN FLUJO PARALELO CON RESPECTO A LA DISTRIBUCION DEL MEDIO OPERATIVO CALENTADO O REFRIGERADO; EL CONTROLADOR DE SISTEMA SE DISPONE DE FORMA QUE GENERE SEÑALES DE ORDEN PARA LAS FUENTES PARA ORDENAR UN AUMENTO O DISMINUCION DE LA CAPACIDAD DE CALENTAMIENTO Y/O ENFRIAMIENTO SEGUN LA TEMPERATURA DEL MEDIO OPERATIVO CALENTADO PROCEDENTE DE SALIDAS PARALELAS DE LAS FUENTES; CADA FUENTE SE CONTROLA CON UN CONTROLADOR SEPARADO AL QUE SE SUMINISTRA UNA SEÑAL DE DEMANDA DESDE EL CONTROLADOR DE SISTEMA; EL CONTROLADOR DE SISTEMA (10) DETERMINA SI DEBE CAMBIARSE LA CAPACIDAD DE CALENTAMIENTO Y/O ENFRIAMIENTO DE LAS FUENTES, COMPARANDO LA TEMPERATURA DE FLUIDO OPERATIVO MEZCLADO PROCEDENTE DE SALIDAS PARALELAS DE LAS FUENTES, CON VALORES DE REFERENCIA PREESTABLECIDOS.
