Abstract

Procedimiento de control adaptativo para sistemas de refrigeración que comprende la detección del nivel de escarcha en el evaporador mediante un método de cálculo de tasa NTU, permitiendo definir: el momento de desescarche más adecuado, la energización de las resistencias de drenaje y la gestión adaptativa del ventilador del evaporador combinando diferentes modos de funcionamiento. Un modo sin hielo que utiliza únicamente la capacidad frigorífica del refrigerante, y distintos modos con hielo que aprovechan el calor latente almacenado en el hielo para producir ahorros energéticos, dependiendo del nivel de escarcha en el evaporador. Para el cálculo de la tasa NTU utiliza como referencia el evaporador cuando está seco al inicio, y cuando el sistema de refrigeración está en funcionamiento, efectúa el cálculo de la tasa NTU con un modo de funcionamiento con frecuencia variable dependiendo del rendimiento del evaporador o nivel de hielo y su comparación con la citada referencia.
