This paper presents a preliminary design of a sustainable, portable solar refrigerator, which uses a solar adsorp-tion system. The aim is to achieve a sustainable design that includes not only the materials but also considertions for the useful life of the equipment and its final disposition. This equipment has been considered as an economical solution for rural communities where there is no electrici-ty, and whose food goods need to be preserved. The suggested design considers a CPC as primary source of energy. For the coolant fluid twosubstances were analyzed: water, methanol. Vegetal carbon is recommended, for this project, as adsorbent material that is usually used in several researches around world as substitute of activated coal. The results are compared with other designs and it was observed that the prototype presented is sustainable and meet sustainable criteria, because is cheaper, portable and uses natural charcoal.
