Question about centrifugal compressors
Dear Friends,
Would you please let me know what is the meaning of this sentence ?
"All refrigeration compressors except centrifugal compressors contain oil"
At centrifugal compressor we do not use oil ?
Sincerely yours.

Re: Question about centrifugal compressors
Generally the motor is external to the compressor and the shaft bearings are also outside of the refrigerant circuit.
There is a lubrication system but it is <within><correction - outside> the refrigerant circuit.
Download the manual for a Carrier 19XRV chiller and look at the lubrication diagram, it will be helpful.
