%X This paper deal<span style=\"font-family:Verdana;\">s</span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> with the evaluation of the Coefficient of
Performance (COP) of solar adsorption refrigeration. In the literature, simulation
models to predict</span><span style=\"font-family:Verdana;\"> the thermal behaviour and
the coefficient of performance</span><span style=\"font-family:Verdana;\"> of these systems are uncommon. This is
why we suggest a model to simulate the operation of the machine in a typical
hot and dry climate of the city of Ouagadou</span><span style=\"font-family:Verdana;\">gou.
The objective is to provide a model for calculating the COP from the</span><span style=\"font-family:Verdana;\"> measurement of the ambient temperature and the irradiation of a given site. </span><span style=\"font-family:Verdana;\">Starting from mathematical modelling, a resolution
and simulation were</span><span style=\"font-family:Verdana;\"> made </span><span style=\"font-family:Verdana;\">with COMSOL
software based on the Dubinin-Astakhov adsorption model,</span> <span style=\"font-family:Verdana;\">the heat transfer balance equations, and the
Linear Driving Force (LDF)</span><span style=\"font-family:Verdana;\"> model </span><span style=\"font-family:Verdana;\">to
describe the thermal behaviour of the system. A one-week measurement </span><span style=\"font-family:Verdana;\">sequence on the adsorption solar refrigerator at
the Albert Schweitzer Eco</span><span style=\"font-family:Verdana;\">logical
Centre (CEAS) validated the numerical results. The measurement</span> <span style=\"font-family:Verdana;\">shows that for the days with high sunshine, the
temperature of the reaction medium reaches 110¡ã</span></span><span style=\"font-family:Verdana;\">C</span><span style=\"font-family:Verdana;\">, </span><span style=\"font-family:Verdana;\">and </span><span style=\"font-family:Verdana;\">the
pressure reaches 500</span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">mbar.
This leads to a</span><span style=\"font-family:Verdana;\"> <span style=\"font-family:Verdana;\">production of cold that allows </span></span><span style=\"font-family:Verdana;\">it </span><span style=\"font-family:Verdana;\">to reach the temperature of </span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">5¡ã</span><span style=\"font-family:Verdana;\">C</span><span style=\"font-family:Verdana;\"> at the</span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> evaporator.
