Abstract: On the basis of thermal calculation, using the flow-path loss method, the selection of impeller's geometric and aerodynamic parameters is proposed for small centrifugal refrigerating compressor and the influence on its parameters and the performance of the compressor are analyzed in this paper. It provides a basis for the selection of the optimum design program of that type compressor.

Key words: centrifugal refrigerating compressor, impeller, aerodynamic parameter
