In the present study the experiments on flow boiling heat transfer in two horizontal smooth tubes are carried out with pure refrigerants HFCl34a, HCFC123, HCFC22, CFC114 and CFC12 using a water-heated double-tube type test section. The test section is 6.0m long, and both copper tubes are of about 8.4 mm inside diameter. The surface roughness is measured and the surface macro-geometry is observed with SEM for both tubes. From the experimental results, the surface effect on flow boiling heat transfer a clarified. A proposed correlation for flow boiling heat transfer coefficient, in which the surface effect is considered, agrees well with the experimental data from different sources.
