Abstract

The improvement of the components of air conditioning system greatly contributes to the energy saving and the reduction of environmental pollutants. The desiccant rotor is a major component from this standpoint because it can reduce the enerev for the humidity control by adsorbing humidity directly to adsorbents. Theoretical analyses considering heat and mass transfer of adsorption and desorption is required to improve its performance. This paper shows experimental data clarifying the theoretical analyses. The adsorption and desorption rates from humid air to a sheet type sillica gel bed, the local temperatures of humid air and a sheet type sillica gel bed are obtained. Moreover the equivalent mass trransfer coefficients are estimated with theoretical calculations, and the influence of airflow rate on the equivalent mass trransfer coefficients is examined.
