WebFreon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. Its properties make it ideal for use in display cases, refrigerated vehicles, ice makers, and other applications. Webcalculation of constants for HFC-134a were performed for Du Pont at the National Institute of Standards and Tech-nology (NIST) under the supervision of Dr. Mark O. McLinden. The constants were calculated in SI units.
