Environmental concerns raised by high global warming potential (GWP) refrigerants have triggered a series of regulatory activities around the world to curtail the use of high GWP hydrofluorocarbons (HFCs) in air conditioning and refrigeration equipment. While the GWP of the refrigerant is a significant contributor to the overall emissions of commercial refrigeration products, it is not the only factor that requires attention. Energy efficiency, maintenance and retrofits are also significant factors that can minimize the carbon footprint of the equipment.
