Abstract

Un aparato para la recuperación de un refrigerante (230) desde un sistema de aire acondicionado (200), comprendiendo dicho aparato (230): - un colector (235) hidráulicamente conectado a una rama de alta presión (221) y a una rama de baja presión (222) del sistema de aire acondicionado (200) con un conducto de alimentación de fluido (101) en dicho aparato (230); - un evaporador (232) dispuesto para separar 10 dicho refrigerante de las impurezas mediante una evaporación de fracciones líquidas residuales de dicho refrigerante, con el fin de obtener un refrigerante purificado que se evapora y eleva hacia una parte superior del evaporador (232) y para obtener impurezas que están concentradas en una parte inferior de dicho evaporador (232); - una unidad de succión (233) para hacer circular el refrigerante purificado que sale de dicho evaporador (232), estando dicha unidad de succión (233) en conexión hidráulica con dicho conducto de alimentación (101) a través de dicho evaporador y la unidad de succión (233) que incluye un compresor; - un condensador (236) en conexión hidráulica con dicha unidad de succión (233), estando dicho condensador (236) dispuesto para condensar el refrigerante que sale desde dicha unidad de succión (233); - un contenedor de almacenamiento (234) en conexión hidráulica con dicho condensador (236), estando dicho contenedor de almacenamiento (234) dispuesto para contener el refrigerante condensado por dicho condensador (236); caracterizado por cuanto que flujo arriba de dicho evaporador (232), está provisto un medio compresor adicional dispuesto en paralelo con dicho conducto de alimentación, estando dicho medio compresor auxiliar configurado para reforzar el caudal de dicho refrigerante que circula hacia dicho evaporador (232) y para servir de ayuda en una reducción de la presión progresiva de dicho refrigerante en dicho sistema de aire acondicionado (200) en cooperación con dicha unidad de succión (233).
