Abstract

Dispositif de récupération de chlorofluorocarbone, permettant d'extraire et de récupérer ce dernier à partir de climatiseurs de voiture, de climatiseurs de maison et de réfrigérateurs à mettre au rebut, et comprenant l'utilisation d'un compresseur (4) de climatiseur de voiture commandé par un moteur pour obtenir une force d'aspiration permettant de récupérer le chlorofluorocarbone. Outre le compresseur, le dispositif utilise également un condenseur (5) pour liquéfier du gaz de chlorofluorocarbone utilisé dans un climatiseur de voiture. Le moteur est utilisé comme source d'entraînement à la fois pour un véhicule et pour récupérer le chlorofluorocarbone, et un tube d'aspiration (10) est connecté à l'orifice d'aspiration du compresseur puis à une soupape d'injection de chlorofluorocarbone d'un climatiseur à mettre au rebut afin d'aspirer le gaz de chlorofluorocarbone. Ce gaz ainsi aspiré par l'intermédiaire du compresseur est liquéfié par le condenseur afin d'être récupéré dans un récipient (17). Des déshuileurs, (8) et (13), sont utilisés respectivement au niveau des côtés d'aspiration et de décharge du compresseur afin de séparer l'huile contenue dans le gaz récupéré, ce qui permet de récupérer uniquement du gaz de chlorofluorocarbone dans le récipient.
