Flow condensation of pure and oil contaminated refrigerant HFC134a in a horizontal tube.

Author(s) : SHAO W., GRANRYD E.

Summary

The heat transfer coefficient in case of oil contaminated refrigerant is shown to depend strongly on the definition of the saturation temperature. Using the pure refrigerant saturation temperature (hence disregarding the influence of oil on the vapour pressure), the results in average heat transfer coefficient show only minor effect of the oil contents. If the saturation temperature of the refrigerant-oil mixture is used, there is thus a considerable degradation of the heat transfer coefficient (as expected) with increasing oil concentrations.
