PART I: EXPERIMENTAL INVESTIGATION OF THE BOILING OF BINARY MIXTURES OF FREON-11 AND REFRIGERATION LUBE OILS.

Several experimental runs have been carried out to study nucleate boiling of binary mixtures consisting of Freon-11 and lube oils such as SUNISO 3GS and 4GS in oil concentrations ranging form 0 to 24% by volume. The effect of the heating source temperature on the rate of boiling at various pressures has been studied and the boiling curves at different oil concentrations and pressures have been investigated at an excess temperature of up to 80 degree C. The heat lost to the atmosphere have also been studied as a function of oil concentration for both kinds of mixtures.
