Abstract
Cooling systems and refrigerators based on adsorption heat transformation processes (AHT) are a green alternative to compression cooling systems. Considering the increasing demand for human comfort, there is a crucial need for next-generation energy-efficient technologies, where the modeling and understanding of all parameters is a milestone. The viability and performance of the technology rely on the selected pair adsorbent/working fluid, but further from their pure thermodynamic performance, processing, and its derivates kinetic factors are depicted high relevant. In this work, ethanol adsorption kinetics on classic commercial adsorbents (activated carbon, AC) are predicted and further determined. The adsorptive phenomenon was investigated by means of computational simulation based on implemented Linear Driving Force (LDF) and the results were compared with experimental adsorption isotherms modeled by using Dubinin-Astakhov equation. The specific cooling effect (SCE) was studied by temperature monitoring during ethanol vapor adsorption experiments in a transient regime.
