Johnson Controls Selects R-454B as Future Refrigerant for New Ducted HVAC Equipment and Air-Cooled Scroll Chillers
The mandate applies only to new equipment specifically designed to utilize R-454B to meet pending GWP limits
MILWAUKEE — After research, testing, and evaluation, Johnson Controls has selected R-454B, a lower global warming potential (GWP) refrigerant, to replace R-410A in its ducted residential and commercial unitary products as well as air-cooled scroll chillers. Systems using the new refrigerant will be available for Johnson Controls, YORK, Luxaire, Coleman, Champion, TempMaster, Fraser-Johnston, Guardian, Evcon, and Quantech branded products in North America, as well as specific international markets where codes are in alignment.
This decision was made as the HVAC industry is preparing to phase out high-GWP refrigerants, such as R-410A, which are now being formally addressed by the Environmental Protection Agency (EPA) through the recently passed American Innovation and Manufacturing (AIM) Act. The AIM Act directs the EPA to phase down U.S. hydrofluorocarbon (HFC) production and use by approximately 85% over the next 15 years.
