Abstract
R404A (FX70) refrigerant is a quasi-azeotropic mixture of R125/R143/R134a with a 44/52/4 component mass fraction ratio. Temperature glide is less than 0,5 °С. Environmental characteristics: ODP = 0, HGWP = 0.94. Initially (since 1993) R404A refrigerant has been used in the new equipment designed for low and middle boiling points.At present time R404A is used for retrofit of the systems operating on R502, and in the new equipment (instead of R22). R404A refrigerant is used in refrigerated containers for obtaining low temperatures, it is also promising for application in ship refrigerated transport.
