Heat-transfer measurements were made for boiling of refrigerants and refrigerant/oil mixtures from smooth and finned tube bundles. The bundles contained 15 heated tubes arranged in an equilateral triangular pitch of 19.1 mm. The outside diameter of the smooth tubes (15.8 mm) was equal to the diameter to the tip of the fins of the finned tubes. The smooth tube bundle was tested in pure R-113 with varying surface "histories" as well as with pure R-114 and R-ll4/oil mixtures. The finned tube bundle was tested in pure R-114 and R-114/oil mixtures. Oil concentrations used were 1, 2, 3, 6, and 10% by mass.
