Abstract

DANS LES COMPRESSEURS ROTATIFS VOLUMETRIQUES CLASSIQUES, REFROIDIS PAR UNE INJECTION DE LIQUIDE, L'EMPLACEMENT DES ORIFICES D'INJECTION RESULTE, A CONDITIONS DE FONCTIONNEMENT DONNEES, D'UN COMPROMIS ENTRE LE RENDEMENT DU COMPRESSEUR ET LA SECURITE DU DEBIT D'INJECTION. UN COMPRESSEUR 10 DESTINE A FONCTIONNER DANS UN DOMAINE DE REGIMES DE FONCTIONNEMENT VARIES EST MUNI DE DEUX ORIFICES D'INJECTION 8 ET 9 ET D'UN COMMUTATEUR DE LIQUIDE 16. LE RENDEMENT EST AMELIORE POUR LES PRESSIONS DE REFOULEMENT ELEVEES ET LA SECURITE D'INJECTION ASSUREE A TOUS LES REGIMES.
