Abstract
Un système de chauffage, de ventilation, de climatisation et de réfrigération (HVACR) comprend un circuit de compression de vapeur et un compresseur couplé de manière fluidique au circuit de compression de vapeur. Le compresseur comprend un premier étage de compresseur comprenant un premier passage de diffuseur, un second étage de compresseur comprenant un second passage de diffuseur, et un système de régulation de diffuseur à géométrie variable (DGV). Le système de régulation DGV comprend un premier anneau DGV positionné à l'intérieur d'une première entrée de diffuseur du premier passage de diffuseur, le premier anneau DGV comprenant une pale, un second anneau DGV positionné à l'intérieur d'une seconde entrée de diffuseur du second passage de diffuseur, et un actionneur d'anneau DGV couplé au second anneau DGV par au moins une tige, l'au moins une tige s'étendant à travers le premier anneau DGV et la pale avant l'accouplement au second anneau DGV.
