Transport properties of ternary near-azeotropic mixtures

In recent years considerable interest has developed in evaluation of alternative refrigerants to CFC12. This paper presents the transport properties of near-azeotropic ternary mixtures of HCFC22, HCFC124 and HFC152a of different composition, namely HCFC22/HCFC124/HFC152a (33/52/15),(53/34/13),(61/28/11) and (36/40/24) respectively, computed over a wide range of temperatures using estimation techniques. The properties are presented in graphical form. Further correlations have been developed to express each property as a function of temperature to facilitate their use in the design of refrigeration systems.
