Abstract
A centrifugal compressor for a chiller includes a first stage impeller, a first stage diffuser, a second stage impeller, a second stage diffuser, and a second stage volute. The first stage impeller is arranged to receive refrigerant from an inlet. The second stage volute is disposed downstream of the second stage diffuser to receive the refrigerant after the refrigerant has been compressed. The second stage volute has a reverse overhung configuration.
