  1. HFO-1234yf Refrigerant IdentificationPeter CollNeutronics Inc. MACS 2009 Dallas, TX

  2. Existing Situation • 100,000+ Active R12/R134a units worldwide. • Measurement of R12, R134a, R22, HC & Air • Technology is NDIR • Price range: $300 - $2000 USD • SAE J1771 Refrigerant Identifier standard • California & Quebec Laws

  3. Principle of Operation IR Source IR Detector Gas Outlet Gas Inlet

  4. HFO-1234yf Products • Software based product • Ready for market within 90 Days • Permits upgrading of 2004 & newer field units • Requires fitting/coupler specification • Requires Firm Industry Direction • Uses Blend ID principle to provide 95 -100% purity indication. • Does not indicate contaminant specifics

  5. HFO-1234yf Products • Hardware based product • On hold waiting for firm direction • New platform with direct NDIR measurement of HFO-1234yf • Requires fitting/coupler specification • Provides full breakdown of purity • Expected +/- 1% Accuracy • Can be integrated into new R/R/R machines

  6. Future Requirements • Revision to SAE J1771 • Determination of performance degradation from mixed R134a/HFO-1234yf • Determination of minimum purity requirements (90%, 95%, 98%)? • Rollout dates and plan for a refrigerant change.
