SAE releases technical white paper on two new low-GWP refrigerants; alternates to R-1234yf

Green Car Congress

These fluids, AC5 (now designated R-444A by ASHRAE) and AC6 (provisionally designated R-445A by ASHRAE), are both based on the HFO R-1234ze(E). Both fluids studied in this project are ternary refrigerant mixtures. AC5 is a formulation of R-32/R-152a/R-1234ze(E) in the nominal proportions (by weight) 12%/5%/83%.
