Thermodynamic property surfaces for various adsorbent/adsorbate pairs for cooling applications

This study focuses on comparative analysis of five different adsorbent/adsorbate pairs regarding thermodynamic property fields based on some well-established mathematical modelling. The thermodynamic property fields such as enthalpy (h), entropy (s) are expressed in terms of temperature, pressure and adsorbed quantity. Moreover, the isosteric heat of adsorption for pairs having a common adsorbent with the three different refrigerants were compared to investigate the effect of adsorbate molecules on the isosteric heat of adsorption. T-s diagrams are analyzed for all the five pairs for different cooling conditions: 5 degrees C, 10 degrees C and 15 degrees C. This information along with the isotherms and kinetics data find immense importance in the computation of energy balances of the adsorbed phase. These results are crucial for rigorous design and analysis of adsorption cooling systems. (C) 2019 Elsevier Ltd. All rights reserved.
