Etude de l’efficacite energetique d’un batiment d’habitation a l’aide d’un logiciel de simulation Boursas Abderrahmane; Mahri Zinelabidine This thesis presents the evolution of the energy situation in Algeria with a comparison to the situation prevailing in the United States, Canada and France. A comparative study is carried out in order to investigate the overall energy consumption by sector and type of energy and the energy policies that reflect this situation, in order to determine the initiatives that should be taken to improve the energy efficiency of buildings for both individuals and the public authorities. The passive energy efficiency measures applied to buildings are being showcased, because these measures lonely can divide the total energy demands of a building in the local weather data. The methodology of this work is based on numerical methods by the dynamic thermal simulation using the simulation software TRNSYS and TRNBuild interface. The result showed that the use of passive energy efficiency measures: the compactness of the building, the distribution of internal rooms and efficient windows with permanent sun protection and thermal insulation for the double wall with hollow brick improves energy efficiency by nearly 2/3, also the use of straw bale as a building material is the most efficient solution in heating, while the stone allows obtain the maximum benefit in term of cooling. 146 f.

Etude et analyse d’un système de production de froid par énergie solaire pour la climatisation Mebarki Billel; Gomri Rabah The aim of this work is the study and analysis of an adsorption air conditioning machine driven by solar energy. We defined the adsorption and desorption phenomena, the adsorbent, the adsorbate and the basic cycle of adsorption refrigeration machine firstly. Secondly, I have mentioned the criteria for selecting the couple adsorbent/ adsorbate, three celebrate couple and different theories modeling adsorption phenomenon. The study of the functioning of adsorption refrigeration machine is addressed by classical thermodynamic analysis of energy balances of the four phases of the cycle. We used the equation of thermodynamic equilibrium which is based on the theory of Dubinin Radushkevich. In order to compare between the three couples most used and the study of the influence of some parameters on the performance of the refrigerating machine. Because the machine is powered by solar energy, so it is necessary to know the hourly solar radiation received by the surface of the solar collector inclined. Therefore, we have developed a computer code to predict solar radiation at every hour of the day. Modeling of solar collector was achieved through an analogy made between the electrical system and thermal system. We have developed a computer code to simulate the operation of the solar collector during four type days of months May, June, July and August. Simulations of the two chiller water adsorption by solar energy, one with one element of sorption, the other with two elements of sorption were realized firstly. On the other hand, we have added the mass recovery process to the chiller of two elements of sorption to investigate the influence of mass recovery on the performance of adsorption chiller water by energy generation solar 97 f.

Optimisation des procédés de climatisation solaire Zid Said; Bennoui Mohamed Salah The aim of this work is to study the integration of solar air conditioning solutions to Algerian climates and to assess economic and environmental benefits. To do this we have made a dynamic simulation two solar conditioning systems that are absorption system and dessiccant system, the simulation have been done under TRNSYS environment, it has given us the possibility to operate with weather data files for the cities of Algiers, Constantine, et Bechar respectively corresponding to a hot and humid climate, a moderated climate, and a hot and dry climate. And since that the proposition of the aims to replace conventional installations with vapor compression, we have simulated one of them which is a vapor compression chiller. The coupling of the studied systems has been made with an office building occupied from 8am to 5 pm to generate thermal loads to be overcome. The obtained results have been presented under a monthly form for the duration of conditioning period for each city with an example for daily profile for each solar system, we have also studied every system/climate coupling compatibility and made conclusions, finally we have made the assessment of the energy cost for each system and also the impact on environment by defining CO2 saved quantities by using each system 98 f.

Production et performance des capteurs hybrides (PV/T) à eau intégrés dans le bâtiment; cas de l'Algérie Kaabi Abdenacer; Benbouza Chaouki The growing interest in the development of the concept of building positive energy for new or very high energy performance for rehabilitation is strongly linked to the global awareness of global warming by greenhouse effect and depletion of primary fossil resources (oil, gas, uranium). Various technological solutions have been there, introduced such as hybrid solar (PV / T) whose principle is to improve the performance of photovoltaic (PV) panels, for recovery of thermal energy they dissipate using a heat transfer fluid (in this case water). The objective of this work is to find a mathematical model first to quantify solar irradiation at a place and on a given day, and has described the thermal behavior of PVT sensor to help determine its electrical performance and heat on a site in Constantine (Algeria). The results obtained show that an energy point of view or primary energy facilities incorporating PVT sensors are very promising and could be competitive in the face of solar systems using photovoltaic and thermal sensors installed separately. The performance evaluation criteria have to be further extended to environmental and economic aspects. 118 f.
