The customer, one of the world’s leading HVAC manufacturers, required the design of a new range of chillers using R1234ze(E) refrigerant. The chiller uses a 2-stage in-line compressor. Both compressors and the return channel need to be designed.
The aim for this project was to design a refrigeration compressor stage using R134a to improve performance of the entire stage (impeller, vaneless diffuser and volute) and to meet various flow rates and pressure ratio requirements by trimming the impeller.
The customer, a leading manufacturer of high speed rotation apparatus and combustion chambers, asked ADT to carry out the complete aerodynamic redesign of a centrifugal compressor stage using TURBOdesign Suite?s inverse design approach.
