Abstract (en)
A centrifugal compressor for a refrigeration or air conditioning system is provided having a variable width diffuser assembly (28) having a movable wall (34) and a plurality of vanes (82). The vanes (82) are angularly disposed relative to the impeller (16) within a critical range of angular values to provide high operating efficiencies and high pressure recoveries over a large operating range.
