Solubility and viscosity of refrigerant/lubricant mixtures: hydrofluorocarbon/alkylbenzene systems

Alkylbenzenes have been found to be applicable in refrigeration systems with hydrofluorocarbons (HFCs). However, little thermophysical property data for HFC/alkylbenzene mixtures have been reported. In this study, the solubility of HFCs in alkylbenzenes, and the viscosity of HFC/alkylbenzene mixtures were measured. The solubility data were correlated with a cubic equation of state with a single adjustable parameter. The viscosity data were correlated with an empirical equation with a simple mixing rule. The solubility of HFCs in alkylbenzenes and viscosity of these mixtures may be predicted with these models.
