Thermodynamic Analysis of an Adsorption Refrigeration System
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 …

Mathematical Study and Steady-State Modeling of Simple Vapour Adsorption Refrigeration System
Abstract: Abstract This paper discusses the mathematical formulation for various heats involved during different processes of a simple vapour adsorption refrigeration cycle having activated carbon and methanol as the active working pairs. This formulation is further used and a detailed analysis of the cycle’s performance is studied based on a steady-state model prepared on the FORTRAN77 platform compiler. The analysis includes effects of the input parameters of the cycle such as …
