Effect of Collector Tilt and Orientation on Performance of Adsorption Solar Cooling System

A solar cooling system can contribute to saving energy and protecting the environment. This paper investigates the influence of tilt and orientation angles of the collector of an intermittent adsorption cooling system. We are interested in the dynamic behavior and the performance of the system under the climatic conditions of Mahajanga city in Madagascar. The heat and mass transfer into the adsorbent bed was modeled. The results showed that the optimal collector tilts vary from 0 to 45° between June and October. It is also observed that an orientation of the collector towards the sunset increases the specific cooling production and the performance.
