Solubility, viscosity and density of refrigerant/lubricant mixtures. Quarterly technical progress report, 1 July 1993--30 September 1993
This report presents results of measurements on low refrigerant concentration mixtures (0, 10, 20, 30 wt %) of CFC-12, HCFC`s 22, 123 and 124, HFC`s 134a, 32 and 125 with mineral oil, alkylbenzene and polyolester lubricants. Viscosity, solubility (vapor pressure) and density data are reported for 23 working fluids composed of combinations of these refrigerants and companion lubricants. These data, reduced to engineering form, are presented in form of a Daniel Chart and a plot of density vs temperature and composition. Extensive numerical analysis has been performed in order to derive equations which allow two independent variables (temperature and composition) and to provide for corrections in composition due to vapor space volume in the test apparatus; details of these calculations are provided.
