EXPERIMENTAL EVALUATION OF THE PERFORMANCE OF BATCH TYPE DESICCANT SYSTEM

The central thrust of this study involves developing a new desiccant-based energy recovery system useful for effective humidity control and featuring integrated design and analysis. The system heat source uses unutilized energy, heated water from solar panels and cool water from cooling towers. It consists of two air-water heat exchangers with adsorbent material coated on the fins and employs directly-heated desorption or directly-cooled adsorption for absorbent material created from the effective reuse of adsorbent materials. This paper describes the adsorption/desorption characteristics and performance of the air-water heat exchanger using the coating absorption material. Measurements involving the moist air being passed into the air-water heat exchanger via the coating of adsorbent material were conducted under various conditions. Consequently, the air-conditioning performance of the proposed system was found to be strongly dependent on the water temperature under constant air condition. The operating cycle of the system was also determined. The measured results make efficient use of the basic data from the numerical analysis model.
