Heat transfer from the water flow to the air flow was examined. When water and air flow parallel in a horizontal duct and the temperature of water is higher than that of air, evaporation of water as well as convective heat transfer from water to air occur. When water evaporates, latent heat is taken out from water. As a result of it, the evaporation of water cools water itself. Thus, water is cooled by both the evaporation of water and the convective heat transfer of the air flow. It was confirmed that the evaporation heat transfer was dominant in that heat transfer; the evaporation heat transfer accounted for approximately 80 % of the total heat transfer rate irrespective of the air flow rate and the water temperature.
