Experimental study of adsorptive solar-powered ice makers in Agadir (Morocco)—1. Performance in actual site

Adsorptive cycles are well adapted to solar refrigeration. Solar ice makers (with an activated carbon + methanol pair) are described. Their major originality lies in the assembly of solar collector and condenser in a unique component: the collecto-condenser. A ‘standard’ ice maker and two prototypes were tested in actual conditions in Agadir, Morocco and this operation is described. Performances are quite good in Agadir; units produce more than 4 kg/m2 of ice for more than 60% of the days investigated.
