ShareDrop-in substitutes for R502: the role of HCFC22 and HC290.
Author(s) : CORTELLA G., BIGOLARO G., SCATTOLINI M., BASILE G., MUSSO E.
Summary
Retrofitting refrigerating units can prove easier and less expensive if the mineral or alkylbenzene lubricants usually adopted with R502 have a certain miscibility in the drop-in mixtures. The paper examines the near-azeotropic mixture R143a-R290-R22 evaluating the influence of the R22 and of R290 mass fractions on the oil miscibility and on operating conditions in the refrigerating units.
