Honeywell announced that more than 2,000 supermarket installations have been completed with its reduced-global-warming refrigerant Solstice N40 (R-448A), making it the industry’s most widely accepted, lowest global-warming-potential (GWP) product.
Supermarkets are the most energy-intensive type of commercial buildings because of their large refrigeration systems. On average, refrigeration systems account for about 50 percent or more of total energy use in a supermarket. Since these systems operate 24/7, year-round, identifying ways to improve energy efficiency can result in meaningful cost savings.
Honeywell’s Solstice N40 is an effective, energy-efficient replacement for commercial refrigeration applications including supermarket equipment, frozen food cases, cold rooms and blast freezers. Solstice N40 is a hydrofluoro-olefin (HFO) blend and has demonstrated 5 to 16 percent lower energy consumption than R-404A in medium- temperature refrigeration applications.
For supermarkets seeking the lowest, commercially available GWP and nonflammable replacement for R-22, R-404A, R-507 and interim blends, Solstice N40 is the replacement of choice as it has a GWP of 1273 (IPCC AR5), which is 68 percent lower than R-404A. The new replacement is listed by the Significant New Alternatives Policy (SNAP) Program and is certified by Underwriters Laboratories (UL).
