Project objective

It has been shown theoretically and experimentally that cooling system operated by solar energy is technically feasible. Such systems find a special interest in subtropical and equatorial regions where solar cooling could be the most widely used | application of solar energy. | Many efforts are done to get the best system allowing easy installation and low financial invests. Among the suitable systems, | those using phase change materials such as hydrated salts, with low-temperature heat. are very promising. Such materials | form an important class of heat storage substances due to their high volumetric latent storage density. We propose to study the storage behavior of such storage materials by thermal and kinetic analysis. The thermal characteristics of the hydrated salts such as CaC12/6H20, Na2S04/lOH20, Na2HP04/12H20 will be determined using calorimetric methods. The kinetic analysis will be performed by the aid of the thermogravemetric method. Training content (objective, benefit and expected impact) The installation of a recent calorimetric method may provide interesting thermophysical properties of such systems. The kinetic parameters associated with the loss of water of crystallization during heating cycles could be obtained using integrated methods. Links with industry / industrial relevance (22) he am of such a study is to determine the storage efficiency of such materials in view to their use in solar cooling systems
