Abstract
We aim at investigating a mathematical model for a desiccant rotor heated directly by concentrated solar irradiation using a non-imaging Fresnel lens in the desorption process. The ray irradiates along with narrow channel in the rotor. The model considered the distribution of solar irradiation in the rotor based on the measurements. In addition, the experiment for measuring dehumidifying rate was performed to compare with the calculation and to confirm the validity of the model. According to this model, the total dehumidifying rate of rotor was predicted by numerical simulation. Finally, the influences of operation parameters such as flow rate, input energy, temperature and humidity on the rate were clarified.
