## 1 Introduction  
Because of the danger posed by the ever-worsening environmental situation on the planet (global warming, depletion of fossil fuels, etc. ), initiatives need to be taken to alleviate the current ambiance. The key to solving this problem is to work out the following scientific and technical goals: (1) the decrease in energy consumption through energy efficiency measures including reducing the share of waste heat (thermal waste from industry, transport, etc.) dissipated to the environment; and (2) the use of alternative energy sources (solar energy, geothermal, waste heat, etc.). These thermal energy sources are characterized by a significantly lower temperature potential than that achieved by burning fossil fuels, which opens up broad prospects for the use of adsorption heat transformation (AHT) systems [1]. AHT is an environmentally friendly technology, which allows the utilization of waste or renewable heat and reduction in the consumption of fossil fuels. Contrary to conventional compression heat pumps and chillers, AHT is characterized by low consumption of electricity, production of which is currently dominated by coal and is expected to remain so. Consequently, the broader dissemination of AHT technology will promote the reduction of indirect emissions of greenhouse gases [2,3]. Moreover, this technology is non-freon because benign liquids, such as water and alcohols, are used as working fluids. Significant progress has been achieved in AHT over the past decades [4,5]. AHT is based on reversible exothermal adsorption and endothermal desorption processes and can be used for various applications, namely cooling, heating, heat storage and amplification, and their combinations. It is well known that the adsorbent that is optimal for AHT must exchange a large amount of adsorbate under the conditions of the cycle under consideration [6]. A high affinity of the adsorbent to the adsorbate is favorable for obtaining a high adsorption capacity. However, such a strong interaction leads to high desorption temperatures (>200-300 \({}^{\circ}\)C), as in the case of zeolites. On the other hand, the low affinity of the adsorbent to the adsorbate favors desorption, but it cannot efficiently convert heat during the sorption phase. Temperature lift in this case will be low. Thus, the optimal adsorbent should provide a moderate affinity for the sorbate, which depends on the boundary conditions of the cycle. In other words, the efficiency of the specific AHT cycle depends mainly on the agreement between the operating conditions of the cycle and the adsorption equilibrium of the employed working pair. The operating conditions of an AHT cycle are determined by the boundary temperatures of evaporator, condenser, and external heat source. They, in turn, depend on the climatic conditions of the region in which the AHT cycle is realized, the application (cooling, heating, heat storage, or amplification), and heat source used for the adsorbent regeneration. Therefore, for effective AHT cycle realization, a working pair \"adsorbent-adsorbate\" should be intelligently selected in accordance with the mentioned boundary conditions of the cycle [6]. There is a fairly large amount of research summarizing data on the adsorption equilibrium of existing working pairs for AHT [7; 8; 9; 10; 11]. Taking into account the importance of harmonization between the operating conditions of the AHT cycle and the properties of the employed working pair, the performance of an AHT cycle is usually evaluated considering the specific climatic conditions of the region where it is realized [12; 13; 14]. For example, the authors of [15] investigated adsorption cooling for storage of vaccines in the Sahara climate. The work [16] considered the organization of the cycle of sorption cooling in Tokyo's climatic conditions. The authors of [17] discussed sorption cooling and the production of warm water in the conditions of the city Dhaka.
