Abstract

In this paper, thermodynamics analysis of an adsorption refrigeration pair (activated carbon and methanol) at adsorption equilibrium conditions has been proposed. Similar analyses have been done by different scientists for different combinations of adsorbent-adsorbate pairs. Adsorption refrigeration processes normally occurs in physical adsorption condition and activated carbon molecules being non-polar in nature, micropores approach of adsorption (Polanyi’s micropores theory and D-A equation) has been followed here. Analysis of the adsorption refrigeration system based on adsorption equilibrium and use of isotherms, isobars and isosteres, has been explained here. Isosteric heat and total enthalpy of the system as a function of pressure, temperature and adsorbate uptake have been calculated. At the end, specific cooling power and coefficient of performance (COP) of adsorption refrigeration system has been calculated.

Keywords: Adsorption, isosteric heat, differential heat isosteres, isobars, isotherms
