Heat Pump Supercharger

Based on research funded by the U.S. Department of Energy and NYSERDA, MSI has developed a high-speed centrifugal compressor for use in cold climate heat pump applications.  The centrifugal compressor works in series with a positive displacement compressor as a supercharge or “booster.”  We successfully designed and built a 100,000 RPM prototype using refrigerant R-410a, including the foil bearing system, aero components, and high-speed permanent magnet motor.  Our research is ongoing in this area.
