Sechenyh V. Viscosity of the solutions the refrigerants with compressor oils (An experiment and prediction methods).

The dissertation is dedicated to experimental investigation and modeling the viscosity of the refrigerant/oil solutions. A new correlation for prediction of the dynamic viscosity for the refrigerants, refrigerant mixtures and refrigerant/oil solutions over wide range of the concentrations and temperatures has been developed. Possibilities of application the structurally-additive methods for calculation the dynamic viscosity for the refrigerant mixtures and refrigerant/oil solutions are considered. Based on result obtained the tables of reference data on the viscosity for solutions of the refrigerant R-600a with the mineral compressor oils Azmol and Reniso WF 15A, and R-245fa with the polyolester compressor oil Planetelf ACD 100 FY are calculated. The tables of the reference data on the thermophysical properties for compressor oils are calculated and presented. Based on result obtained the viscosity-pressure-temperature diagrams for real working fluid are developed.
