Abstract

Un sistema de control de sobreconcentracion para utilizarse con una máquina de absorcion del tipo que tiene un ciclo de calentamiento y de enfriamiento de efecto ya sea individual, doble o triple, el cual utiliza bromuro de litio en solucion con agua, como el líquido de operacion. El líquido de operacion se caracteriza por una concentracion indicativa de la cantidad del bromuro de litio disuelto en el agua, y por un diagrama de fase que tiene un límite de cristalizacion que define las combinaciones de concentracion y temperatura, las cuales corresponden a una condicion de saturacion en la solucion. Se proporcionan medios detectores a una ubicacion predeterminada dentro del sistema, los cuales responden a la profundidad de la solucion para generar una señal de concentracion indicativa de la concentracion de líquido. También se proporciona un detector de temperatura para generar una señal de temperatura indicativa de la temperatura de líquido. Además se proporcionan medios los cuales responden a la señal de temperatura y a la señal de concentracion para calcular una representacion del ciclo de absorcion de la máquina, que puede ser representada en un diagrama de fase para el sistema de bromuro de litio. La representacion incluye una pluralidad de puntos de estado críticos, los cuales son definidos por combinaciones respectivas predeterminadas de concentracion y temperatura.
