An investigation has been carried out on condensate subcooling near the tube exit during horizontal in-tube condensation, both experimentally and analytically. In the experiment, test fluids used were Refrigerants R113, R11, R114, and R12. Condensate subcoolings of larger than 10 K were measured, even before condensation was completed, and data of condensate temperature profiles were obtained along the adiabatic section following the condensing section. Analysis, based on a nonequilibrium heat transfer model, could closely predict experimental data both for condensate subcooling at the condensing section exit and for condensate temperature profiles in the adiabatic section.
