Résumé: This paper presents a mathematical model which describes process of moisture transfer from the adsorbent bed and air filtrated through the bed. The model of the packed bed column takes into consideration mass transfer in the bed as well as water diffusion and adsorption in a new composite sorbent “CaCl2/alumina”. The model is applied to describe evolution of vapor concentration at the exit of experimental unit for regenerating moisture in ventilation systems, which has recently been suggested, build and tested. Sorption equilibrium of water vapor on the new sorbent has been studied to be used as input parameter in the model. Good agreement between experimental and calculation data demonstrated that the model adequately reflects main physical and chemical features of the regeneration processes. Hence, it can be used for modeling a scale-up effect and for magnification of the unit from laboratory to larger size, e.g. single room, family house and large residential buildings.
