Development of the Centrifugal Compressor for a R134a Turbo-Chiller Part 1 : Design of the Centrifugal Compressor

R134a용 터보냉동기의 원심압축기 개발 Part 1 : 원심압축기 설계

The present study has been conducted to design the high efficiency centrifugal compressor for a R134a turbo-chiller. The centrifugal compressor consists of an impeller with splitters, two vaneless diffusers, a low-solidity vaned diffuser and a volute. A cycle analysis program for a turbo-chiller was developed to obtain compressor design parameters and requirements. We have designed the high efficiency centrifugal compressor by applying the repeated design procedure including a meanline design, a 3D geometry generation and fluid dynamic loading calculations.
