While dealing with low-GWP refrigerants to help slow - and ultimately reverse - the process of global warming a new class of mildly flammable refrigerant called A2L is one of the topics under discussion. Customers are specifically testing the refrigerants R32, R1234yf, and R1234ze, as they provide low GWP, zero Ozone Depleting Potential (ODP), and a relatively low flammability. Performed tests with R32 were satisfactory and it seems possible that this substance could prevail.
R407A/F is a blend of R32, R125 and R134a, and is related to R407C, but has a pressure which better matches R22. With the recently started discussion to reduce the GWP on refrigerants, R407A/F could also be an alternative as R404A/R507 replacement. The GWP of R407A/F is with 1800 lower as for R404A which 3900. R407A/F is an alternative in both medium- and low temperature applications in commercial refrigeration systems. It is non-flammable and has only low toxicity.
