ShareSolubility, viscosity, and density measurements of refrigerant-lubricant mixtures. 1. Branched acid pentaerythritol polyolesters with R134a.
Author(s) : CAVESTRI R. C., MUNK J., MENNING M.
Summary
The equilibrium gas solubility, viscosity, and density of R134a in synthetic 32 ISO VG and 100 ISO VG branched acid pentaerythritol polyolester lubricants were measured by an oscillating body viscometer that allows direct measurement of density and gas concentration at isothermal and at equilibrium pressure conditions. Specifically, the concentration of dissolved gas ranges from 2 to more than 65% by weight in the specified temperature range of -25 to 125 deg C and within the highest pressure of 3.5 megapascals.
