An overview on adsorption pairs for cooling

This study is a survey for working adsorbent-refrigerant pairs and the new pairs for potential applications. The study introduces a classification for the adsorption cooling systems and a comparison between them based on the employed adsorption pairs. The comparison is on the basis' of the limits of use such as coefficient of performance (COP), driving temperature, evaporation temperature and specific cooling power (SCP). The study also introduces a review of the most promising new adsorption pairs. The new pairs are introduced from the point of view of its adsorption characteristics. Finally, the study concluded that the future of adsorption cooling could be more popular as it will offer answers for the existing challenges. (C) 2012 Elsevier Ltd. All rights reserved.
