Experimental investigation on adsorption capacity of ACF–methanol pairs for cooling application

ABSTRACT

Solar cooling technology is very popular among other conventional cooling technologies due to increment in global warming effects. In solar cooling technology, solar-powered adsorption refrigeration system has potential to compete with other non-conventional cooling technologies, that is, Absorption, PV-based, Waste-heat-driven and Biogas cooling. The main objective of this research work was to investigate the adsorption capacity of methanol onto activated carbon fibre in the temperature range of 15–80°C during an isobaric adsorption process. To correlate adsorption characteristics’ data of the experiment, the Dubinin–Astakhov equation is used. From a series of experiments, the maximum adsorption capacity was found to be 0.44 kg/kg of ACF by maintaining packing density of bed at 110 kg/m³. The effect of heat generator temperature on adsorption capacity is also studied in this investigation.
