Abstract

Una disposicion de control de sobre-concentracion para uso con una máquina de absorcion del tipo que presenta ya fuera un ciclo de enfriamientoy calentamiento de efecto unico, doble o triple que utiliza bromuro de litio en solucion con aguacomo el líquido de funcionamiento. El líquido defuncionamiento comprende una concentracion indicativa de la cantidad de bromuro de litio disuelto en agua, y por un diagrama de fase que presenta un límite decristalizacion que define las combinacionesde concentracion y temperatura que corresponde a una condicion de saturacion en la solucion. Se provee unmedio sensor en una ubicacion predeterminada dentro del sistema que resulta sensible a la profundidad de dicha solucion para generar unasenal deconcentracion indicativa de la concentracion del líquido. Se provee también un elemento termosensible para generar una senal de temperatura indicativade la temperatura del líquido. Se proveen otros medios más que resultan sensibles a la senal de temperatura y la senal de concentracion para calcularuna representacion del ciclo de absorcion de la máquina que se puede trazar sobre un diagrama de fase para el sistema de bromuro de litio. Larepresentacion incluye una pluralidad de puntos estado críticos que se definen por combinaciones respectivas predeterminadas de concentracion ytemperatura. Se proveen también medios para comparar la concentracion y temperatura actuales del líquido a las concentraciones y temperaturas queyacen sobre dicho límite de cristalizacion para bromuro de litio para generar una senal de diferencia. Se proveen medios de control que resultansensibles a la magnitud de la senal de diferencia para cambiar el estado defuncionamiento de dicha máquina como fuera necesario para evitar que el
