湿り空気中における伝熱(冷却の場合)

As the heat and mass transfer problem of humid air cooling on finned pipe is necessary for air conditioning, the auther researches the heat transfer coefficient for finned pipe cooler. The cooler is set perpendicular to air flow and cooled by brine with temperature -5∼0°C. From the the results, it ts recognized that the analogy between heat and mass transfer exists and that the ratio of both coefficient α/k is about 0.21 kcal/kg°C. The ratio of heat transfer coefficient for wet and dry surface can be calculated from the experimental formula or nomograph of it.
