ABSTRACT
The performance analysis (stability of desorption and adsorption equilibrium, refrigeration effect and the COP) were determined using MNAC and compared with CAC at 1.0, 0.8, 0.6 and 0.4g/g initial adsorbate capacity under same experimental conditions and were found comparable with each other. MNAC and CAC both exhibited stable desorption and adsorption equilibrium. The refrigeration effect achieved was only suitable for chilling water from 28 - 20, 28- 19, 28- 19.5 and 28- 20oC for MNAC- methanol and 28- 19, 28- 18, 28- 19 28- 19.50C for CAC- methanol at the studied initial adsorbate capacities, this low performance was linked to vacuum control, low thermal conductivity necessitating low refrigerant desorption quantity with consequent effect on the quantity re- adsorbed at the evaporator that cause cool production. The COPs for MNAC- methanol at the investigated adsorbate capacities were 0.079, 0.044, 0.028 and 0.030. Those for CAC- methanol were 0.074, 0.029, 0.019 and 0.017 respectively, this compared favourably with other works. Mango nuts activated carbon can thus be suitable replacement as activated carbon for adsorption refrigeration application.
