Aim\ To economize energy and protect environment. Methods\ Solid absorption solar energy refrigeration are used and a prototype model is made to verify the principle and used to search for those materials which are low cost

nonpoisonous and easy to be gotten. Results\ The charcoal and industrial alcohol are selected as the medium. Refrigeration efficiency can reach \{150.8 kJ·kg\+\{-2\}·m\+\{-2\}\}. Conclusion\ Experiments prove that the principle is valid.
