This document reviews adsorption cooling systems. It introduces adsorption cooling and discusses traditional working pairs like silica gel/water as well as newer metal organic framework (MOF) materials like phthalic acid/water. The document outlines the basic process of an adsorption cooling system using a schematic and descriptions. It then reviews relevant literature on improving adsorption cooling system performance through better working pairs and adsorbent materials like MOFs. The conclusions discuss benefits of adsorption cooling like not requiring moving parts but also challenges like heat losses during the adsorption and desorption processes. Future work opportunities include enhancing heat transfer rates during these processes and optimizing adsorbent/adsorbate proportions and designs.
