Centrifugal compressor assembly and method |
| abstract |
A centrifugal compressor assembly (24) for compressing refrigerant in a 250-ton capacity or larger chiller system (20), the centrifugal compressor assembly comprising a mixed flow impeller (56, 58) and a vaneless diffuser (112) sized such that a final stage compressor (28) operates with an optimal specific speed range for targeted combinations of head and capacity, while a non-final stage compressor (26) operates above the optimum specific speed of the final stage compressor. |
