Medium temperature thermal energy, obtained by solar trough concentrating technology, is utilized to provide the steady heat source for the adsorption refrigeration system by using the heat storing devices. The project will build the thermodynamic model of the adsorption refrigeration cycle based on the adsorption bed using concentric tube with fins, achieve the temperature distribution and the pressure distribution in the adsorption bed with the medium temperature thermal source, and discover the flow and heat and mass transfer characteristics of the adsorbate in the adsorption bed. By optimizing the structure of the concentric tube with fins, the thermal energy from the heat source could be transferred to the adsorbent quickly and uniformly, and the adsorbed/ desorbed refrigeration fluid - the adsorbate could be taken away rapidly. By studying the correlations of the desorption amount and the desorption time with the heat source temperature, the optimum driving temperature would be reached. By controlling the energy supply to the adsorption refrigeration system, the adsorbed/ desorbed refrigeration period would be shorted, and multiple adsorbed/ desorbed refrigeration cycles daily would be realized, thereby enhance the overall refrigerating efficiency of the system. To match the solar trough concentrating thermal supply with the adsorption refrigeration energy use, the study on the energy output characteristics of the solar trough concentrating collector as thermal energy provider, and the matching of the solar trough concentrating collector with the thermal energy storing device would be performed. The relative experimental setup would be build to realize the steady adsorption refrigeration cycle in the condition of the unsteady energy source from solar energy.
