Abstract
This paper presents the operating and performance of an adsorption refrigeration system
driven by a solar collector. The thermodynamic cycle and the working principle of the system
are based on the adsorption phenomena at a steady temperature. The system operates with
activated carbon (AC)-methanol as a working pair, and Dubinin-Astakhov (D-A) equation
was used to describe this phenomena. Comparative study between different types of AC
reveals that the one based on stone coal had an optimal performance coefficient (COP) equal
to 0.73 whereas a total energy input to the system is 18740.05kJ and a total daily ice
production of 13.65kg at -3°
C. The studied case indicates that the optimal performance of the
system can be obtained for low ambient and condensation temperature with high evaporation
temperature. Ice produced can also be improved when the initial water temperature is low.
