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.
