Abstract
In this paper, effect of using metallic additives on thermal conductivity of granular activated carbon has been investigated. Fillings of iron, copper and aluminum at different mass concentrations ranging from 10 to 30% have been studied. The thermal conductivity of the combinations has been estimated experimentally. The thermal conductivity has been increased with the increase in metal concentrations. A mathematical model simulating an adsorption cooling system has been conducted. The effect of the metallic fillings on coefficient of performance and specific cooling power (SCP) of adsorption cooling system has been studied theoretically. Using aluminum fillings in 30% concentration caused a decrease in cycle time by 50% and an increase in specific cooling power by 100%.
