Abstract

Un sistema de refrigeracion comprende un compresor para comprimir un refrigerante, un condensador para condensar el refrigerante en un liquido, un evaporador para evaporar el refrigerante liquido del condensador en un gas, un ciclo de control interno para optimizar un suministro de refrigerante liquido al evaporador, y un ciclo de control externo para optimizar un nivel de refrigerante en el evaporador, dicho ciclo de control externo definiendo una velocidad de suministro para dicho ciclo de control interno basado en una optimizacion incluyendo la medicion del rendimiento del evaporador, y dicho ciclo de control interno optimizado el suministro definida. Las variables independientes, tal como la proporcion de aceite en el refrigerante, cantidad de refrigerante, contaminantes, no condensables, escala, pueden estimarse o medirse. Un modelo del sistema y/o un modelo termodinamico que se aproxima al sistema, por ejemplo, derivado de los medidores de presion y temperatura, asi como tambien las mediciones o computos de energia, se emplea para determinar o estimar el efecto sobre la eficacia de desvianza de un estado optimo. Se proporcionan diversos metodos para regresar el sistema a un estado optimo, y para calcular un coste-eficacia del empleo de tales procesos.
