  • Refrigerant compressor with impeller having blades with wavy contour
    Patent number: 11988221
    Abstract: This disclosure relates to a refrigerant compressor including an impeller. The impeller has a blade with a wavy contour. The wavy contour reduces flow separation relative to smooth, non-wavy blades. In particular, the disclosed wavy contour creates smaller trailing edge vortexes adjacent the blades. In turn, the wavy contour of the blades improves overall compressor efficiency.
