Analysis numerical of one-dimensional heat transfer for desert house
Journal Title: Recueil de mécanique - Year 2017, Vol 2, Issue 1
Abstract
The main objective of this work is to study the thermal exchanges in order to optimize the solar contributions in a habitable enclosure located in a desert region of Algeria (ADRAR). The enclosure walls are the only capacitive elements of the enclosure. They are thermally coupled by conduction, convection and radiation. The external facades of the enclosure are the seat of a convective flux with the external air and radiative exchanges with the environment (ground and sky). The thermal exchanges are studied using the balance equations established at each wall of the enclosure. These equations are discretized by an implicit finite difference method. The system of algebraic equations thus obtained is solved by the Gauss algorithm using the nodal method. The effects of the outdoor ambient temperature, the density of the incident solar flux and the orientation of the habitable enclosure on the temperatures distributions throughout of the internal walls and the filled air in the enclosure are analyzed. The evolution of the internal ambient temperature as a function of the wind exposure factor and the degree of leak tightness of the doors and windows is also highlighted at the end of this work.
