Several selected refrigerant mixtures are tested as potential short- and mid-term substitutes for CFC12 and R502. HCFC22 and some hydrocarbons are considered as components of retrofit mixtures. Their influence on the solubility of various lubricant oils is investigated by measuring critical solubility temperatures. The performance of the CFC12 and R502 refrigerants and of their proposed alternatives is compared by testing two different refrigerating units

Abstract

Several selected refrigerant mixtures are tested as potential short- and mid-term substitutes for CFC12 and R502. HCFC22 and some hydrocarbons are considered as components of retrofit mixtures. Their influence on the solubility of various lubricant oils is investigated by measuring critical solubility temperatures. The performance of the CFC12 and R502 refrigerants and of their proposed alternatives is compared by testing two different refrigerating units
