Etude numérique des performances thermiques d'un habitat bioclimatique

Abstract : This research is based on a numerical study of thermal performances of a bioclimatic habitat. In this study, we considered two bioclimatic habitats, one concerning a conventional aluminum roofing habitat, wood-wool false ceilings, and the second, a habitat incorporating a MCP panel that separates the roof into tiles transparent parallelepipedic enclosure. The heat transfer equations in the habitat are based on the nodal method and are deduced from a heat balance established for the different components of the habitat. The heat transfers in the storage unit are focused on the enthalpy and purely conductive method. They are solved by an implicit finite difference method and the Gauss and Thomas algorithms. We analyzed the influence of certain parameters such as: solar flux, wall thickness, maximum and minimum temperature, and the rate of air exchange on the temperature distributions of the components of the habitat and water. Storage unit, the thermal efficiencies of storage and retrieval of the storage unit. A modeling of the heat transfer phenomena in the habitat and in the storage unit is presented, completed by a simulation of the functioning of the system based on the notions of typical day through the meteorological data of the region of Ouagadougou and ended by a technical and economic analysis.
