In the present work, an experimental investigation on the adsorption and desorption operations in an internally cooled solid desiccant bed has been made. Experimental system involves a finned tube heat exchanger containing particles of silica gel, which is tested at different air flow rates and different of particles silica gel. The inlet and exit air temperature and relative humidity, air velocity, the inlet and exit water temperature and water flow rate are measured. Moisture removal rate is calculated. The results show that the internally cooling significantly enhances the performance of desiccant bed and the adsorption process can be done at nearly isothermal process. The enhancement in bed performance can be more than 50% due to internal cooling. Moisture removal rate sharply increases by increasing air flow rate in both adsorption and desorption processes. Increasing the regeneration temperature significantly improves the desorption performance of the bed for example by increasing it from 41.5 oC to 63 oC the moisture removal rate increases from 2.8 g/s to 5.4 g/s.
