Abstract
Tests to compare and understand the adsorption capability of some locally produced activated charcoal (coconut shell) samples with methanol were taken under laboratory conditions. An experimental test rig was set up. Data obtained from the experiments were fitted to Dubinin-Radushkevitch (D - R) and Dubinin-Astakhov (D - A) equations. The results obtained and can be used to select the most favorable pair. Activated carbon AC-5060 shows the best adsorption capacity for methanol and the highest coefficient of performance (COP). This is chosen as the adsorbent in a dual purpose solar adsorption system. The adsorption system is subjected to parametric analyses. The parameters such as second adsorber bed temperature, condenser temperature, and mass of ice are varied and performance evaluated. Malaysian activated carbon is not significant for ice making in the dual purpose adsorption systems at condenser-adsorption temperature equal or higher than 35°C. The most efficient way to improve the dual purpose system under the hot climate is to search for enhanced adsorbent material in terms of adsorption capacity and thermal conductivity.
