An experimental and numerical study of the operation of an adsorption solar refrigerator using the zeolite-water couple is presented. The experimental consists of measuring the solar radiation incident on the collector-absorber, the temperature of the collectoradsorber, of the condenser and the one of the evaporator. The numerical part concerns a modeling and a simulation of the functioning of this refrigeration system. Transfer equations are deduced from thermal and mass balances established at each component of the refrigerator. The Dubinin-Astakhov equation is adopted for the adsorption kinetics of the zeolite-water pair. The results are presented by the evolution over time of the temperatures of the components of the solar refrigerator (absorbent plate, condenser, evaporator, etc.), as well as the pressure adsorbed, adsorbate mass and SCOP.
