Title (EN) CONTROL OF THE ATMOSPHERE IN AN ENCLOSURE
(FR) CONTROLE DE L"ATMOSPHERE DANS UNE ENCEINTE
Abstract: front page image
(EN)A method of controlling an atmosphere in an enclosure (12) to which gas (40) is being supplied comprises the steps of monitoring (53) atmospheric pressure within the enclosure and the rate of gas flow to (52) or from the enclosure, comparing these parameters (62) with adjustable set points to obtain error values and adjusting inflow (50) and exhaust (51) valves for the enclosure in dependence upon the error values. A preferred method includes the intermediate steps of deriving from the error values, target position for the valves. Also disclosed is an installation incorporating a control system for carrying out the method.
(FR)Le procede de controle de l"atmosphere a l"interieur d"une enceinte (12) dans laquelle on envoie du gaz (40) comprend les etapes consistant a controler (53) la pression atmospherique a l"interieur de l"enceinte et la vitesse d"ecoulement de gaz vers (52) ou a partie de l"enceinte, comparer ces parametres (62) avec des points ajustables definis de facon a obtenir les valeurs des erreurs et a ajuster les soupapes d"admission (50) et de refoulement (51) de l"enceinte par rapport aux valeurs des erreurs. Un procede prefere comprend les etapes intermediaires consistant a deriver des valeurs des erreurs les positions-cibles pour les soupapes. Une installation incorporant un systeme de controle pour l"execution du procede est aussi decrite.
