Concentration shift in refrigerant mixtures.

[In German. / En allemand.]

Type of article: Article

Summary

Mixtures become an alternative to R22 and R502. At the moment non-azeotropic mixtures like R407A or R407C, near azeotropic mixtures like R404A, and azeotropic mixtures are available as substitutes with refrigerant mixtures. Fractionation in the case of leakage, or a different oil solubility, may occur, influencing the pressures and temperatures of the refrigerant cycle and perhaps the energy performance and possibly leading to flammable refrigerant compositions.
