N2 - Adsorption heat transformation is an energy and environment saving technology for cooling/heating driven by renewable energy sources. Each specific cycle of adsorption heat transformer (AHT) makes particular requirements to the properties of the sorption material, depending on the climatic zone in which the AHT is used, the type of application (cooling, heating and heat storage), and energy source used for regenerating the sorbent. Therefore, the effective operation of AHT can be realized only if the working pair "adsorbent-adsorbate" is intelligently selected in accordance with the requirements of a particular working cycle. One of the most important factors influencing the choice of a working pair is the climatic conditions in which the AHT will operate. In this paper, the climatic conditions of various regions of Russian Federation (RF) were analyzed. For each considered zone, the boundary potentials of Polanyi corresponding to different AHT cycles are calculated. The sorption equilibrium data of various sorbents with water and methanol presented in the literature are summarized, and characteristic sorption curves are plotted in coordinates "sorption - the Polanyi potential". The characteristic adsorption curves found are approximated by analytic expressions, which allow the analysis of working pairs applicability for different AHT cycles. The recommendations of using the discussed sorption pairs under conditions of determined climatic zones are given for the AHT applications.
