This book was released on 2005 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude a pour objet la recherche d'innovations dans le domaine des chauffe-eau solaires afin d'améliorer le ratio "production de chaleur 1 investissement' de cette technologie. Dans ce but, la démarche de travail a consisté, dans un premier temps, à établir le bilan énergétique détaillé d'un chauffe-eau solaire en fonctionnement pour repérer les points faibles du système et cibler l'apport d'innovation. Pour ce faire, l'outil numérique de simulation dynamique TRNSYS a été utilisé. L'analyse du bilan énergétique du chauffe-eau solaire a montré l'intérêt de réduire les niveaux de températures auxquels le système fonctionne. On peut ainsi espérer réduire les déperditions thermiques et donc fonctionner à un meilleur rendement, mais aussi ralentir la dégradation du matériel due aux sollicitations thermiques. En suivant cette voie de recherche, nous nous sommes intéressés au stockage de chaleur latente dans des matériaux à changement de phase. Le principe de fonctionnement thermique de ces matériaux permet d'envisager un stockage de chaleur beaucoup plus dense qu'un stockage de chaleur sensible dans l'eau, dans des plages de températures intéressant directement la production d'eau chaude sanitaire. Ces matériaux peuvent donc servir de stockage de chaleur et de régulateur des niveaux de températures du système. Un ballon de stockage, intégrant des matériaux à changement de phase encapsulés dans des nodules sphériques, a donc été élaboré puis modélisé. La modélisation des transferts de chaleur dans les matériaux à changement de phase repose sur une méthode appelée enthalpique. Des essais en laboratoire sur un prototype expérimental de ce ballon de stockage ont permis de vérifier le bon fonctionnement du modèle numérique. Grâce au modèle développé, on a pu simuler, dans l'environnement TRNSYS, un chauffe-eau solaire intégrant un stockage à chaleur latente et obtenir ainsi son bilan énergétique détaillé. La comparaison de ce bilan énergétique avec celui d'un système classique a permis d'évaluer l'intérêt de l'innovation. Compte-tenu de la complexité du comportement thermique des matériaux à changement de phase et des simplifications i adoptées par le modèle numérique, il faut rester prudent sur l'analyse des résultats de simulation. Toutefois, ceux-ci révèlent des tendances très positives du nouveau système. Le stockage de chaleur latente sert en effet de régulateur thermique du système et réduit sensiblement les niveaux de températures auxquels fonctionne le chauffe-eau solaire. D'un point de vue numérique, les perspectives de travail concernent un perfectionnement du modèle numérique dans sa précision mais surtout dans ses temps de calcul. Ceux-ci sont trop élevés et empêchent une étude numérique complète du système dans des délais raisonnables. Avec un modèle perfectionné, on pourra mener une recherche du meilleur dimensionnement du stockage à chaleur latente permettant d'optimiser les performances du chauffe-eau solaire. D'un point de vue technologique, une étude technico-économique devrait montrer l'intérêt industriel de l'innovation développée qui est basée sur la simplicité et ne devrait pas entraîner de surcoût rédhibitoire

Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.
