Numerical Analysis of Solar Refrigerating System Performances

In this preset work, we investigate the solar and the thermal performances of the adsorption refrigerating system, considering an annular and plate finned configurations of the adsorber using BPL-ammonia as an adsorbent-adsorbate pair. The obtained results show that, for the two working pairs, the increase of the fins number corresponds to the decreasing of the heat losses towards environmental and the increasing of heat transfer inside the adsorber. The system performances are sensitive to the fins geometry. For the considered data measured for a clear type day of September 2023 in Algeria, the performances of the cooling system are very significant.
