The Implementation of Numerical Codes for the Analysis of Solar Flux Inputs and the Optimization of Thermal Comfort for a Monobloc Habitat

Abstract

The purpose of this work is to design computer codes to estimate the different thermal exchanges of the facades of a habitable envelope with its environment in order to optimize thermal comfort. This optimization is based on the use of real climate data from the region under consideration. To achieve this goal, we have developed five fundamental codes in FORTRAN language. The first code consists in Modelling the flow of the heat transfer fluid in the heating slab pipe. The second is designed to model the heat transfer by conduction within the concrete slab. The third is developed for the Modelling of thermal exchanges in a habitable envelope assimilated to a parallelepipedal cavity based on the nodal method. The fourth code is reserved for the Modelling of solar radiation by evaluating the wage flux density on different positions of the walls. The fifth and last code is dedicated to the evaluation of the perfect thermal coupling between the concrete slab and the heat transfer fluid pipes. The validation of the models implemented in the calculation codes was made on the basis of data measured recently for a clear sky of solar radiation at the radiometric station of the renewable energies research unit in the Saharan environment URER’MS of Adrar. The results obtained showed a very good agreement between the calculated values using the computational codes developed and those measured by the radiometric station of the URER’MS during the typical day.
