Abstract:
Traditional food preparation requires fossil fuel producing pollution which induce to ecosystem’s damage, deforestation and health diseases. Solar cooker such as box type can be one of the solutions of this critical problems. This research paper deal with the temperatures and efficiency mapping of a realized box solar cooker. The cooker is designed with inclined aperture area, tested in Saharan hot climate of Ghardaîa. Several maps are generated by this study for summer and winter clear skies such as global solar radiation and concentrated irradiances. By using Black body temperature equation’s, maps for absorber temperatures are obtained, the efficiency map of the realized cooker is then deduced which allow the determination of the most exploitable areas corresponding to the climatic conditions of Algeria. It is found that the cooker can be used during all the year’s months in south regions of Algerian Sahara. In Sahara center regions, the use of the cooker will be reduced to 10 months (from February to November). The height plain can cook food with this device in all seasons of year accept in winter. However, the littoral regions can use the cooker only for 6 months in summer and spring seasons.
