A Porous Medium Materiel Used In Solar Energy Conversion
Intense research on development of ozone and global warming protection heat pump machine technology is observed, because of the international environment protection. In arid areas, electricity network is not often available or it is at high price while the sun is shining and the cooling demand is important during almost the year. Absorption refrigeration has been intensively investigated over the world, during the last twenty years. This report is concerned by the solar energy conversion and use in an absorption cooling process where a specific porous medium is used to improve the efficiency. This process is the best appropriate solution to refrigeration and air conditioning problems in the desert areas and other remote countries where electricity power network is not available. The simulation of absorbing/desorbing chemical reaction in a solar cooling system, working according to absorption principle has given some results allowing to confirm the efficiency improve, the economical and technical feasibility and to avoid difficulties.
