Solubility, viscosity and density of refrigerant-lubricant mixtures.

Author(s) : HENDERSON D. R.

Summary

Solubility (vapour pressure), viscosity and density have been experimentally determined for thirty-five potential refrigeration working fluids. Properties for low refrigerant concentration mixtures (0, 10, 20 and 30 wt% refrigerant) were determined over the temperature range 0 to 100 deg C or to the critical temperature of the refrigerant, and pressure range 0 to 3,500 kilopascals. High refrigerant concentration data (80, 90 and 100 wt% refrigerant) is given covering -40 to 40 deg C in most cases. The working fluids studied include selected combinations of R12, R22, R32, R123, R124, R125, R134a, R142b, R143a and R152a with mineral oils, alkylbenzenes, polyolesters (both mixed acid and branched acid) and a polyalkylene glycol. Results are presented in the form of a Daniel chart, which includes isobaric viscosity curves, and equations.
