Description
R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing.
R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact.
