Title (EN) A DEVICE FOR DRAWING OFF COOLING AGENTS FROM REFRIGERATION AND HEATING PLANT
(FR) DISPOSITIF POUR LA VIDANGE D"AGENTS REFRIGERANTS DANS UNE INSTALLATION DE REFRIGERATION ET DE CHAUFFAGE
Abstract: front page image
(EN)A device for drawing off cooling agents from refrigeration and heating plant such as heat pumps and large cooling installations, for instance. The present invention consists of a connecting pipe (14) intended to be connected to the system which is to be drained, said connecting pipe (14) discharging into a sealed tank (5), with a compressor (1) connected on its suction side to said tank (5) and on its delivery side connected in series with a condenser (4), a heat exchanger (17) located either inside or adjacent to said tank (5) and a filling cylinder (13) or similar, in that order. The operation of the compressor (1) will thus cause the cooling agent to flow down into the tank (5), to be compressed by the compressor (1), to be condensed and to give off heat as it passes through the heat exchanger (17), causing the cylinder (13) to be filled via a pipe (21).
(FR)Dispositif pour la vidange d"agents refrigerants dans une installation de refrigeration et de chauffage telle que, par exemple, des pompes a chaleur et des grandes installations de refroidissement. La presente realisation se compose d"un conduit de connexion (14) a connecter au systeme qui doit etre vidange, ledit conduit de connexion (14) se dechargeant dans un reservoir scelle (5), avec un compresseur (1) dont le cote d"aspiration est connecte audit reservoir (5) et le cote de refoulement est connecte en serie avec un condenseur (4), un echangeur de chaleur (17) situe soit a l"interieur soit adjacent audit reservoir (5) et un cylindre de remplissage (13) ou similaire, dans l"ordre mentionne. Le fonctionnement du compresseur (1) provoquera ainsi l"ecoulement de l"agent refrigerant dans le reservoir (5), afin d"etre comprime par le compresseur (1), etre condense et ceder de la chaleur lors de son passage a travers l"echangeur de chaleur (17), provoquant le remplissage du cylindre (13) par un conduit (21).
