Résumé

A new method, equivalent to a dry-bulb temperature method, is proposed for calculating the heat and mass transfer and for predicting the cooling modes (totally wet, partially wet, and totally dry) of moist air over the coil surface. A numeric model is further developed and validated with the experimental data of plain fin air coils. The deviation in both the cooling capacity and the vapour condensate estimated by the model is within the range of plus or minus 10%, and the prediction for the cooling modes of moist air over the coil surfaces is fairly exact.
