Abstract

This paper reports experimental data for the solubility, density and capillary constant for solutions of refrigerant 1,1,1,3,3-pentafluoropropane (R-245fa) with polyolester compressor oil Planetelf ACD 100FY over a wide range of temperatures and concentrations. The experimental data were obtained in the temperature range from 333 to 425 K and at pressures up to 33 bar using static methods. Based on information for the capillary constant, the surface tension of the solutions R-245fa/Planetelf ACD 100FY is determined. The enthalpy of liquid phase of the R-245fa/Planetelf ACD 100FY solutions is calculated. The analysis of the behaviour of the excess thermodynamic functions is carried out. Information about the changing concentration of refrigerant in the liquid phase of the refrigerant/oil solutions (ROS) and in the surface layer of the liquid phase of the ROS at increasing temperature is presented.
