Small oil-free piston-type compressor for CO2.

Author(s) : BAUMANN H., CONZETT M.

Summary

The objective of this project was to prove the feasibility of a small oil-free semi-hermetic piston-type CO2 compressor for supercritical heat pump applications with large temperature spans. These processes involve high pressures such as 35 bar suction pressure and 80 to 150 bar delivery pressure. A functional compressor model was designed and manufactured, and performance was tested over the full range of speed and pressure. The tests confirmed the feasibility of the technology for use in small oil-free CO2 compressors.
