Abstract

Un sistema de refrigeración en múltiples niveles de evaporación, que funciona de acuerdo con un ciclo de compresión de vapor y que comprenden un segundo circuito que tiene una rama de alta presión HP, en la que está dispuesto al menos un intercambiador de calor 10, y dos o más ramas baja presión LP1, LP2, LP3, cada uno de los cuales opera a un nivel diferente de la evaporación para servir a los usuarios que tienen diferentes necesidades de refrigeración. En cada una de la rama de baja presión de la planta de que comprende un miembro de rodadura 11’, 11’’, 11’’’ al menos un evaporador 12’,12’’, 12’’’ y una unidad de compresor 13’, 13’’, 13’’’. El mencionado al menos un evaporador de cada rama baja presión (LP1, LP2, LP3) es directamente conectado a dicha rama de alta presión (HP). Al menos una primera rama de baja presión LP1 comprende un separador de líquido 20’ que está conectado de manera fluida: la salida del evaporador 12’ para recoger el líquido en la salida del evaporador de la misma en el caso en el que este opera en condiciones de comer en exceso; y la admisión del conjunto del compresor 13’. Tal líquido separador 20’ no está conectado de forma fluida a la entrada del evaporador de dicho primer ramal de baja presión (LP1), pero está conectado de forma fluida a una segunda rama de LP2 baja presión que funciona a un segundo nivel inferior de la evaporación de la primera aguas arriba de la laminación 11’’ de esta segunda rama de baja presión a través de una primera conexión de conducto 21’. El circuito comprende primeros medios de válvula 22’, 23’ controlable de tal manera que la segunda rama de baja presión se alimenta alternativamente de la rama alta presión o desde el separador de líquido a través del primer conducto de conexión. Estos primeros medios de válvula son accionados para permitir evaporador de alimentación 12’’ de la segunda rama de baja presión con líquido desde el separador de líquido 20’ de la primera rama de la evaporación cuando se hace el evaporador de la primera rama de la evaporación para operar en condiciones de sobrealimentación con el fin de disponer el líquido que se acumula en dicho separador de líquido.
