Solstice family of HF Solstice family of HFOs
Low Low Global War lobal Warming ming Molecules olecules 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(E) • HFO-1234ze, is currently replacing R-134a for one-component 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.
