Abstract
Mejoras en la regulación de centrales de acondicionamiento de fluidos. Se caracterizan porque, cuando la presión en el punto de medida alcanza o sobrepasa el valor de la presión de arranque y/o cuando el caudal proporcionado por los dispositivos de bombeo es inferior al caudal de consumo, el caudal proporcionado por la central aumenta un escalón y, cuando la presión en el punto de medida alcanza el valor de la presión de paro y/o cuando el caudal proporcionado por los dispositivos de bombeo es superior al caudal de consumo, el caudal proporcionado por la central disminuye un escalón. Según otra realización, un dispositivo de bombeo se para o queda en funcionamiento sin bombeo ("stand by'') cuando el citado dispositivo de bombeo se encuentra en condiciones de trabajo tales que pueden producir una reducción de la vida del dispositivo de bombeo o un calentamiento excesivo del mismo. Se consigue un ahorro importante de energía y un aumento de la vida útil de los dispositivos de bombeo.
