In line with the Kigali Amendment, developed countries are committed to reducing the use of HFCs incrementally, starting with a 10 percent cut by 2019 and reaching 85 percent by 2036. Most developing countries have committed to freezing the production and import of HFCs starting in 2024; and the remainder will begin in 2028. All of these actions will expedite the transition to next-generation refrigerant replacements. Environmental impact, safety and energy efficiency have become the three most frequently discussed topics as users seek new alternatives that meet the requirements of the Kigali Amendment and can be used safely and effectively to retrofit existing equipment or in new installations. Honeywell’s Solstice® N40 (R-448A) is a new, reduced-GWP refrigerant for commercial refrigeration, now available in the Asia Pacific region. Supermarkets, convenience stores, cold storage warehouses, and other applications that require lowand medium-temperature refrigeration equipment can now reduce their environmental impact and energy consumption with Solstice N40. As the lowest-GWP, non-flammable, retrofit refrigerant available today, Honeywell’s Solstice N40 is designed to provide customers with a near drop-in replacement for previousgeneration solutions such as R-22 and R-404A. In supermarket trials conducted in the U.S. and Europe, Solstice N40 demonstrated 3 percent lower energy consumption in lowtemperature applications, and 5 to 16 percent lower energy consumption in medium-temperature applications compared with R-404A.
Solstice N40 has a GWP of 1273, which is 68 percent lower than R-404A’s 3943. It reduces operating costs by helping stores reduce their energy consumption by up to 16
percent. It is expected to achieve up to a 40 percent reduction in carbon dioxide (CO2) emissions in four years’ term. As the equipment design for Solstice N40 is similar to R-404A and R-22, it enables continual use of existing hardware and can therefore support retrofitting or renovation of stores, in addition to new installations. Solstice refrigerant solutions are safe for the intended use and capable of making a significant positive environmental impact.
