NEW HFOs PROPOSED TO COVER HCFC AND HFC ALTERNATE SOLUTIONS

NEW HFOs PROPOSED TO COVER HCFC AND HFC ALTERNATE SOLUTIONS

30.05.2014

Complementing established HFOs, new HFO molecules and blends have been developed for specific applications.

A blend containing mainly HFO-1123 (1,1,2 – Trifluoroethene, CHF=CF2) is proposed to replace R-410A in stationary air conditioning. The blend has an GWP of 350, one sixth of R-410A.

HFO-1336mz-Z ((Z)-1,1,1,4,4,4-Hexafluoro-2-Butene, CF3-CH=CH-CF3) is a non –flammable liquid (BP 33 C), with a GWP of 9.4, and has been proposed

– as polyurethane foam blowing agent for high performance foam

– as working fluid for high temperature heat pumps

– and as a replacement for HCFC-123.
