High-speed, direct-drive centrifugal compressors for commercial HVAC systems.

Author(s) : BRONDUM D. C., MATERNE J. E., BIANCARDI F. R., PANDY D. R.

Summary

The paper describes progress being made on the development of small capacity (e.g. 10-100 tons) direct drive, oil-free centrifugal compressors. The technology development required for successful application involves high speed motors and drives, centrifugal aerodynamics, oil-less bearings, controls, system modelling, and heat exchangers operating with environmentally safe HFC refrigerants. A consortium has been formed for the purpose of developing and demonstrating this concept. A prototype compressor is now being tested in actual system applications in the Syracuse development laboratories of Carrier.
