  • 2.  Honeywell.com Regulatory Requirements Call for Innovation Honeywell Committed Resources & Technology2 Honeywell Proprietary and Confidential
  • 3.  Honeywell.com Low Global Warming Molecules New Hydro-Fluoro-Olefins have been developed: HFO-1234yf has been identified as replacement for R134a by the automotive industry.  It has an atmospheric life of only 11 days (12 years for HFC-134a) and an extremely low GWP of only 4 (1430 for R-134a).  ASHRAE std 34 has classified HFO-1234yf as low toxicity class A. HFO-1234yf HFO-1234ze, is currently replacing R-134a for one-component HFO-1234ze(E) foam applications and looks promising for centrifugal chillers.  This molecule also has a very short atmospheric lifetime with a GWP of 6.  ASHRAE std 34 has classified HFO-1234ze as low toxicity class A. Another molecule is currently under development and is code named N12.  Intended refrigerant application is low pressure centrifugal chillers. High temperature Heat Pumps and ORC.  It has a GWP of 7 and is non-flammable.3 Honeywell Proprietary and Confidential
