Answer to Question 1

Centrifugal compressors are able to pump large volumes of refrigerant as compared to reciprocating compressors. However they do not develop the high side discharge pressures of a reciprocating compressor. Since low pressure refrigerants do not require such high discharge pressures, they are ideally suited for centrifugal chiller applications.

Answer to Question 2

A single stage centrifugal compressor only has one impeller while a two stage unit would have two impellers. Multiple stage units develop higher pressures as compared to single stage units.
