Aluminium Based Zeolites and MOFs for Adsorption Cooling

Abstract

In this paper, AQSOA-Z01, AQSOA-Z02, AQSOA-Z05 zeolites, CAU-10 and Aluminium Fumarate metal organic frameworks undergo N2 and water adsorption experiments to observe how variations of the material properties affect the water adsorption performances. The experimentally measured N2 isotherms data are used to calculate the BET surface area, pore volume and, most importantly, the pore size distribution of these adsorbent materials. The amount of water uptakes under static and dynamic conditions are measured by a thermo-gravimetric analyser, and these data are fitted with adsorption isotherms and kinetics models within acceptable uncertainties. Based on isotherms and kinetics data, the performances of adsorption cooling in terms of SCP (specific cooling capacity) and COP (coefficient of performances) are evaluated. It is shown the CAU-10 provides the highest SCP and COP as it has higher water uptake – offtake differences with fast kinetics.
