Thermal behavior and performance assessment of a solar adsorption cooling system with finned adsorber

The analysis of the thermal behavior of adsorbent indicates that heat and mass transfer within the adsorbent is enhanced by increasing the number of fins. The simulation results show that, under the climatic, operating and design conditions of the system, the solar coefficient of performance is roughly invariant with changes in number of fins. The results indicate also that the thermal coefficient of performance is improved by increasing the number of fins. However, it is found that there is an optimal range of number of fins varying from 15 to 20 that allows obtaining an optimal performance; the corresponding range of fin spacing is found to be between 4 and 5.2 cm.
