 Abstrak

This study investigates the performance of a solar adsorption refrigerator using activated alumina and methanol adsorption pair. The experiments were carried out for 24-hour. The refrigeration was completed during seven cycles with varying weather conditions. A flat plate type collector was used with an area of 0.25 m2 and tilt angle of 30o. Theoretical calculations show that, the maximum collector efficiency is 47.15% when the maximum solar radiation obtained is 936.9 W/m2. In this research, the maximum value of the COP is 0.0991 when the total solar energy is 16.485 MJ/m2 and the minimum value obtained is 0.0919 when the total solar energy is 7.609 MJ/m2. The experiment results show that the adsorption pair system can deliver an evaporator temperature of about 9.92°C and the cooling load can be achieved by a heat source with a temperature range of 83.95°C and 95.39oC.
