- Abstract
In this study, a new Regenerative evaporative cooler (REC) sample was made, and heat and moisture transfer characteristics were investigated. Heat and moisture transfer model was developed, which incorporated salient features of REC, for example air leakage between channels, entrance region, non-uniform overall heat transfer coefficient, etc. Comparison of the model with limited experimental data revealed favorable results. There existed optimum extraction ratio, which maximizes the cooling capacity. On the other hand, dew point efficiency increased as extraction ratio increased. Parametric study revealed that dew point efficiency increased as dry channel inlet temperature or hmidity increased. However, cooling capacity decreased as humidity increased.
