Study and numerical simulation of solar system for air heating

Abstract

The use of solar energy in sunny countries, is an effective outil for compensate the lack in the energy, their  benefits are not related only to its economic benefits but especially for the environmental protection, so we  must find solutions to the problems of pollution. This work is a theoretical study of a solar flat plate collector;  air is used as the heat transfer fluid. In this study, we established in first step calculation of solar radiation in various sites in Algeria (Adrar, El Oued, Bechar, Biskra and Tamanrasset). The second step is the parameters  influence study of the sites and climate on the performance of our collector. The results obtained are encouraging for the use of this type in the heating in the winter; also it can be used in different kinds of drying.
