Génie ClimatiqueTags : Adsorption couple adsorbent / adsorbate solar collector mass recovery Adsorption couple adsorbant/adsorbat capteur solaire récupération de masse الامتزاز زوج المكثف / الكثف مجمع الطاقة الشمسیة استرجاع الكتلة 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 : 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 [Algérie] : Université Constantine 1, 2014 . - 97 f. ; 30 cm.

Génie ClimatiqueTags : Adsorption Froid Gel de silice/eau Force motrice linéaire (LDF) Modélisation COP Cooling Silica gel/water Linear driving Force Model (LDF) امتزاز تبريد جال السيليس الماء Index. décimale : 626 Génie Climatique Résumé : The aim of this thesis is to study the influence of the constructive parameters of an adsorption bed on the performance of a two-bed adsorption chiller and on the temperature distribution of the adsorbent, the rate of the adsorbate and the pressure in the adsorption bed.
In the context of the choice of the adsorbent-adsorbate couple, a very important step in optimizing the performance of an adsorption refrigeration machine, a static model of an adsorption cooling machine was developed. A FORTRAN computation code corresponding to this model has been established allowing the best choice of the adsorbent-adsorbate couple.
The performance of two adsorbent bed silica gel-water adsorption chiller and the influences of its adsorbent bed dimensions, the velocity of heat exchange fluid and the adsorbent particle diameter on the transient distributions of the solid phase temperature, adsorbate concentration and the pressure are numerically examined in this study.
A transient two-dimensional local thermal non-equilibrium model that takes into account both internal and external mass transfer resistances is developed to simulate the adsorption chiller considered herein. The internal and external mass transfers are predicted by the linear driving force (LDF) model and Darcy’s equation, respectively.
The results of our simulations provide useful guidelines for the design of this type of adsorption chillers.
