Note générale : 2 copies imprimées disponibles Langues : Français (fre) Tags : Adsorption couple adsorbent / adsorbate solar collector mass recovery Adsorption couple adsorbant/adsorbat capteur solaire récupération de masse ???????? ??? ?????? / ????? ???? ?????? ??????? ??????? ?????? Index. décimale : 626 Génie Climatique Résumé : 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 solarDiplôme : Magistère En ligne : ../theses/gclim/MEB6446.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9481 Etude et analyse d’un système de production de froid par énergie solaire pour la climatisation [texte imprimé] / Billel Mebarki, Auteur ; Rabah Gomri, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 97 f. ; 30 cm.

Index. décimale : 530 Physique Résumé : Solar energy is the most important source of renewable energy, hover the exploitation of
solar energy in Algeria is a major focus of research who knows a great development over the past
decade. Currently there are two main ways to exploit solar energy; solar photovoltaic energy
radiation that turned directly into electricity, solar thermal, which directly converts radiation into

Langues : Français (fre) Tags : Cellule PV capteur solaire verre PMMA air eau nanofluides modélisation simulation performances PV cell solar collector glass water nanofluids modeling ??????? ??????????? ????? ?????? ??????? ?????? ????? ?????? ?????? ??????? ???????? Index. décimale : 626 Génie Climatique Résumé : The growing in demand of energy risks exhausting totally different conventional fields, so in order to mitigate many states turn to deal with it and in the same time they wanted to maximize performance with less costs.
Thus we have developed a study highlighting the use of solar by introducing the hybrid photovoltaic / thermal collector consisting of a PV module under which a heat exchanger is provided to ensure the cooling of the cells.
The energy produced will be used to generate electricity and heat. At this stage we have studied the feasibility by taking two elements that are plastics as cover and nanofluids as cooling fluid.
Regarding plastics, these have proved to be the most widely used materials for the manufacture of various components, in particular those of solar heating ... etc.
As for nanofluids, it is a new technology that has revolutionized all those that have preceded it because they have high thermo physical properties.
At this stage, the study proposes the simulation of two different systems in forced convection inside the fluid channel, both for plastics and for nanofluids, the two systems proposed were based on the development of an energy balance between the different nodes of the system.
Hence the equations will be discretized and then introduced into a program written in Matlab for the purpose of calculating the unknowns and also being able to validate our results.
The results show that the use of PMMA is beneficial for transmitting more radiation compared to the glass and as for the nanofluids, the extraction of the heat under the panel proved to be better compared to the conventional fluids.

????? ?????? ???? ???????? ???????Index. décimale : 626 Génie Climatique Résumé : 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.

Langues : Français (fre) Tags : chauffe eau solaire capteur solaire ballon de stockage installation solaire stratification échangeur de chaleur solar water heating solar collector Storage tank solar installation heat exchanger ???? ?????? ??????? ??????? ????? ?????? ??????? ????? ???? ?????? ??????? ??????????????? ????? ????? Index. décimale : 530 Physique Résumé : The stratification in a Storage tank is the key for the good functioning of all installation aiming at meeting thermal needs (production of sanitary hot water, home heating).
The work undertaken in this dissertation focuses on the modeling of a storage tank in order to understand better the thermal behavior of the latter one. The impact of many parameters (water injection debit, the nature and the thickness of the insulation, usage of a heat exchanger or an electrical booster) on the temporal evolution of the temperature (in case of charge and of discharge) in the tank was examined.
The modeling of the stratification is undertaken by subdividing the tank into N (20) layers. An energy and a masse balance is drawn up in every node. The system of the global equations is resolved by the Crank-Nicolson method.
The results obtained show clearly that the last layer heats faster, especially as the injection debit is elevated and the tank homogenization time becomes shorter.
Besides, it appears that a good isolation allows to minimize the losses, and to avoid the creation of convective current, which could degrade the stratification.
The comparison of the numerical results obtained in this work with those of the literature shows a good agreement.Diplôme : Magistère En ligne : ../theses/physique/BOU6632.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9757 Modélisation d'un ballon de stockage thermique [texte imprimé] / Hamza Bouchetiba, Auteur ; Abla Chaker, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 128 f. ; 30 cm.
