The adsorption of refrigerants on solid adsorbents can be applied in environmentally friendly solutions for cooling or heating demands. The frequency response analysis is extended and applied to investigate the adsorptions dynamics and the adsorption equilibrium of water on coatings with the metal–organic framework (MOF) aluminium fumarate. Based on the obtained loading- and temperature-dependent heat and mass transfer parameters, effective thermal resistances of 1–4 (m2 K)/kW are calculated, about one order of magnitude lower than state-of-the art silica gel beds. A design case study yields specific cooling powers of 0.2–0.7 kW/l at heat exchanger level.
