After evaluating several low global warming potential (GWP) refrigerant alternatives on a variety of performance and market metrics, including safety, capacity efficiency, reliability, availability, and longevity, R-454B was chosen as the best solution to minimize environmental impact and energy use.
When replacing R-410A, engineers should consider commercially available, single-component, or azeotrope refrigerants that meet AHRI Standard 700 with zero ODP and a maximum 750 GWP.
Hydrofluorocarbons (HFCs), as the name suggests, are compounds containing hydrogen, fluorine, and carbon. They are used for residential and commercial heating, ventilation, and air conditioning (HVAC) as refrigerants, by firefighters as a fire suppressant, and in aerosols as propellants.
