Concept of adsorbent optimal for adsorptive cooling/heating

In this paper, we consider the role of adsorbents in adsorptive cooling/heating (ACH) and analyse which are optimal for specific ACH cycles. The conclusions are formulated in terms of the optimum isobar shape, the Dubinin adsorption potential being used as a universal measure of the affinity between the adsorbent and the adsorptive. Selection/tailoring of the optimum adsorbents, creation of database of their properties as well as harmonization of the adsorbent and other components of ACH unit, cycle boundary conditions, and cycle management strategy are briefly discussed. New efficient adsorbents harmonized with particular ACH cycles are a prerequisite to achieving a major breakthrough in ACH, and therefore, are pivotal for this challenging application.
