Abstract
Several experimental runs have been carried out to study the condensation of binary mixtures consisting of Freon-11 and lube oils such as SUNISO 3GS and 4GS in oil concentrations ranging from 0 to 24% by volume. The effect of cooling-water flow rate and temperature on the rate of condensation on the outer surface of a helical coil has been investigated at various pressures and oil concentrations. These experimental data have been used to calculate the overall- as well as the outer (film)-heat transfer coefficients as a function of the logarithmic mean temperature difference, cooling water flow rate, and total pressure of the vapor phase.
