| Résumé : |
Afin d’assurer le confort thermo-aéraulique dans les constructions, il sera utiliser utilise pour cette étude l’échangeur air-sol seul on couplé au panneau solaire photo-thermique comme moyen de chauffage ou de rafraichissement pour réaliser ce travail, plusieurs typologies de constructions seront étudiée pour dégager aussi bien la configuration que la constriction de l’enveloppe des constructions en vue de déterminer la combinaison optimale de ceux paramètres assurant le meilleure confort avec le minimum de consommation énergétique aussi hivernale que estivale. In this thesis work, numerical CFD and experimental studies are carried out to study the behavior of an air / soil heat exchanger and its efficiency, the purpose is to study the feasibility of connecting this exchanger with a building to reduce its consumption electric energy. In the hottest periods, the efficiency of this exchanger is reduced and does not reach the temperature of comfort; which forces us to use conventional air conditioners. The problems that arise with the use of residential air conditioning are that under the very high temperatures in summer in the south of Algeria and that can sometimes exceed 50 ° C. What makes the heat exchange between the air conditioner and the outside environment very difficult causes the problem of thermal comfort inside the building and the cost of energy consumption. The solution proposed in this work is to couple our air / ground heat exchanger with the condenser of this air conditioner to improve the efficiency of the air conditioner and reduce its energy consumption. The model of the Hollmuller heat exchanger is taken into account in the mathematical formulation of the problem under the TRNSYS environment. The results found show a net reduction of energy consumed by about 0.14 KWh and 21%, that the costs in Algeria are 100 DA in 72 hours or 12403.8 DA / year. On the other hand, the typology of constriction of buildings makes our model more efficient when respecting building standards with good insulation. On the other hand the typology of constriction of buildings makes our model more efficient when complying with building standards with good insulation, with values of heat loss U between 0.15 and 0.24 W / m²K. |
