Two stages centrifugal compressor using R134a as working fluid for a 145RT class chiller has been developed. Each stage of Centrifugal compressors is connected by return channel. An aerodynamic design was done by applying the repeating design procedure including a meanline design, a 3D geometry generation and fluid dynamic calculation. The performance test was also conducted by the experiment. So, in this paper, design, performance prediction and experiments results for two stages turbo refrigerant compressor will be presented.
