Title (EN) RECOVERY SYSTEM FOR N20
(FR) SYSTÈME DE RÉCUPÉRATION POUR N20
Abstract:
(EN) A system for the recovery of expanded refrigerant from a cryotreatment system for storage and disposal may generally include first fluid flow path having a first compressor and a fluid recovery reservoir, and a closed-loop second fluid flow path having a thermal exchange device that is in thermal communication with the fluid recovery reservoir, a second compressor, and a condenser. The first fluid flow path may include a primary refrigerant from a cryotreatment system and the closed- loop second fluid flow path may contain a secondary refrigerant for cooling the primary refrigerant within the fluid recovery reservoir. The refrigerant recovery conduit may be in fluid communication with both the cryotreatment system and a medical facility scavenging system. The refrigerant recovery conduit and the cryotreatment system may be located within the same cryotreatment console.
(FR) L'invention concerne un système pour la récupération de réfrigérant dilaté provenant d'un système de cryotraitement pour le stockage et l'élimination, qui peut généralement comprendre un premier trajet d'écoulement de fluide ayant un premier compresseur et un réservoir de récupération de fluide, et un second trajet d'écoulement de fluide à boucle fermée ayant un dispositif d'échange thermique qui est en communication thermique avec le réservoir de récupération de fluide, un second compresseur et un condenseur. Le premier trajet d'écoulement de fluide peut avoir un réfrigérant primaire provenant d'un système de cryotraitement, et le second trajet d'écoulement de fluide à boucle fermée peut contenir un réfrigérant secondaire pour refroidir le réfrigérant primaire dans le réservoir de récupération de fluide. Le conduit de récupération de réfrigérant peut être en communication fluidique avec le système de cryotraitement et un système d'évacuation d'installation médicale. Le conduit de récupération de réfrigérant et le système de cryotraitement peuvent être placés dans la même console de cryotraitement.
