In the present work, a rotating tilted wick, which is made of a double layer cotton-cloth, has been used as a desiccant regenerator. Calcium chloride solution is applied as the working desiccant. The wick surface, which is impregnated with the desiccant solution, moves between two rotating pulleys at an inclination angle of 20 degrees. The regenerated solution carried by the wick returns to the solution tank at the end of a complete cycle. Desiccant solution concentration in the tank is evaluated and recorded with time. Instantaneous as well as average values of the mass transfer coefficient are evaluated from the experimental measurements. Mathematical model, which can be applied for the prediction of solar radiation intensity and analysis of the proposed system, is developed. Model validation shows a good agreement between measured and predicted values of radiation. Apparent values of system coefficient of performance around 2 could be attained in the dry climate of Taif city. Finally, system operational problems are discussed and highlighted.
