Abstract

Sistema de refrigeración de amoniaco/CO2 que comprende aparatos que funcionan en un ciclo de refrigeración de amoniaco, un enfriador (3) de salmuera para enfriar y condensar CO2 utilizando el calor latente de vaporización del amoniaco, y una bomba (5) de líquidos prevista en una línea (52) de suministro para suministrar el CO2 enfriado y licuado a un enfriador (6) del lado de carga de refrigeración, en el que dicha bomba (5) de líquidos es una bomba de descarga variable para permitir que el CO2 circule de manera forzada, en el que dicho enfriador (6) del lado de carga de refrigeración puede permitir la evaporación incompleta de CO2 líquido a un estado mixto gas/líquido, y el sistema de refrigeración comprende además: un controlador para determinar el flujo de circulación forzada de manera que se recupere CO2 de la salida del enfriador del lado de carga de refrigeración en un estado líquido o mixto líquido/gas; caracterizado por que comprende: un paso (30) de alivio para conectar dicho enfriador (6) del lado de carga de refrigeración al enfriador (3) de salmuera o a un depósito (4) de líquido previsto aguas abajo del mismo, además de un paso de recuperación de CO2 que conecta la salida de dicho enfriador (6) del lado de carga al enfriador (3) de salmuera, en el que la presión de CO2 es aliviada a través de dicho paso de alivio cuando la presión en el enfriador (6) del lado de carga es igual o superior a un valor predeterminado.
