ABSTRAKT

The use of solar energy in cooling systems is an interesting alternative to the increasing demand of energy in the world, and more specifically in southern countries where the needs of refrigeration and air conditioning are tremendous. This technique is even more attractive with regard to environmental issues. Solar thermodynamic cycles based on absorption or adsorption are useful in many refrigeration applications. The present study deals with a solid adsorption refrigerator analysis using different adsorbent/adsorbate pairs. It is a contribution to the development of solar cooling systems technology. This technology is useful in the Algerian climate. The main objective consists of analyzing the heat and mass transfer in an annular porous adsorber, which is the most important component of the system. The thermal and solar performances of the system are evaluated for different pairs and optimal situations are highlighted. The porous medium is contained in the annular space and the adsorber is heated by solar energy. A general model equation is used for modeling the transient heat and mass transfer. The effects of the key parameters on the adsorbed quantity, the performance coefficients, and thus on the system performance are analyzed and discussed.
