Freon™ 404A (R-404A) | HFC Refrigerant | Freon™ Refrigerants
Freon™ 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.
R-404A - 百度百科
制冷剂R404A是新装制冷设备上替代 氟利昂 R22 和 R502 的最普遍的工业标准制冷剂（通常为低温冷冻系统），R404A最接近于R-502的运作，它适用于所有R-502可正常运作的环境，R404A得到全球绝大多数的制冷 设备制造商 的认可和使用。 但是由于R404A与R502和R22物化性能、理论循环性能以及压缩机用油等均不相同，因此对于初装为R502和R22制冷剂的制冷设备的售后维修，如果需要再添加或更换制冷剂，仍然只能添加R502和R22，通常不能直接以R404A来替 …

Freon 404A
New tables of the thermodynamic properties of Freon™ 404A (R-404A) refrigerant (ASHRAE designation: R-404A [44/52/4]), a near azeotropic blend of HFC-125/HFC-143a/HFC-134a, have been developed and are presented here. These tables are based on extensive experimental measurements. Equations have been developed, based on
There are significant differences between R-502, R-404A, and R-452A, which must be considered when handling, processing, applying, or retrofitting with these refrigerants. These guidelines are offered to help understand the differences. NOTE: R-404A is a near azeotrope and therefore needs to be charged in the liquid phase.
