OPTIMIZATION OF INCIDENT FLOWS ON THE WALLS OF A HABITAT FOR A TYPICAL CLIMATE IN THE UPPER REGION IN REPUBLIC OF GUINEA

The aim of this work is to develop a mathematical model of the solar radiation incident on the walls of an inclined roof habitat for a typical climate of Guinea and to highlight the influence of the variation in the angle of inclination of the roof. Thereafter, we set up a program for the determination of all its parameters under the Fortran Language and plot our curves through the Origin software. This work allowed us to know, the amount of solar flux that each wall of a habitat receives, the importance of the orientation of the main facade of the habitat to the south, how often the roof is exposed to radiation solar and the influence of the variation of the angle of inclination of the roof compared to the horizontal. For example, for an angle of 15 ° the maximum value of the solar flux received is 547 W / m2 and for that of 75 ° is 995 W / m2. Thus, the optimal angle obtained from analyzes of the variation of solar radiation with respect to the inclination of the roof through Figure 7 is 60 °.
