Heat and mass transfer characteristics from air with high water vapor content on a spirally finned tube heat exchanger were experimentally investigated. The experimental results are summarized as follows. The convective heat transfer coefficient with condensation of the water vapor is almost same as that without condensation. The mass transfer coefficient is enhanced by increasing the water vapor content in the air, and is different from that evaluated by means of analogy between the haat and mass transfer. This means that the analogy does not hold for the finned tube heat exchanger. It was found that the effect of the water vapor content is caused by the difference of the wet fin surface on which the mass transfer occurred.
