Abstract
Pool boiling HTCs (heat transfer coefficients) of R134a and R12 outside horizontal enhanced tubes have been experimentally measured for pure medium. The influence of oil additive on the heat transfer has been compared for three enhanced tubes. The results indicate that the oil has different impact on the heat transfer coefficients of different enhanced tubes.
