Snižování energetické náročnosti procesu profesní údržby prádla / Energy Intensity Reduction of a Professional Laundry Care Process

Bobák, Petr January 2014 (has links)
Doctoral thesis deals with professional laundry care process and reduction of energy intensity and use of other operational commodities used in the process. Professional laundry care process is a specific energy intensive process; its purpose is to re-establish original properties of the now dirty laundry so that it may fulfil its functions again. This is basically a recycling and regeneration process comprising many sub-operations. Key operation is washing of the laundry in a washing bath, which removes impurities from the laundry. This thesis describes the most common technology of impurities removal, which is washing in a hot washing bath in cooperation with mechanical work and detergents. However, all of the described procedures may also be applied on alternative technologies, such as ozone washing, washing with low-temperature enzymes and ultrasound. Water is applied in all these technologies as a soaking agent. Water must have appropriate properties and must be removed from the laundry after the washing process in subsequent operations (drying, ironing, and pressing). Theoretical introduction of the thesis describes professional laundry care process in detail, and continues with mathematical modelling of the process and its main sub-operations (washing, drying) using mass and heat balance, and data acquisition and their application in research and development. Thesis further describes design of information system on the basis of relational database controlled by web application. This system enables to organize data and information from various sources – measured experimental data, data concerning measurement devices, operational records of machines, etc. Thesis further proposes how to evaluate and reduce energy intensity of a process. Descriptions are validated by examples and case studies. Key section of the thesis is a chapter describing experimental infrastructure. This infrastructure integrates several instalments of laundry equipment and is a fully functional operation of industrial laundry facility with 500kg/shift capacity, which serves as a model of energy intensive process. Sophisticated infrastructure and data acquisition system allows measuring wide spectrum of physical entities and examining factors influencing energy intensity of processes, and relationships between these factors as well as effectiveness of various savings measures in real life facilities.

Développement d’une méthode de méta modélisation des consommations énergétiques des bâtiments en fonction des facteurs d’usages et d’exploitation pour la garantie de résultat énergétique / Development of a metamodel for building energy consumption as a function of space use and HVAC systems operations factors for energy performance guarantee

Novel, Aymeric 07 January 2019 (has links)
À mesure que les performances intrinsèques des bâtiments s’améliorent, les usages énergétiques non réglementés, que nous associons à une notion d’intensité énergétique des usages, prennent de plus en plus d’importance dans le bilan des consommations des bâtiments. De plus, les bâtiments performants font apparaître des problématiques au niveau de l’exploitation des installations. Ces constats nous permettent d’affirmer qu’il est aujourd’hui important de proposer un cadre pour le suivi et l’optimisation de la sobriété énergétique des usages et l’exploitation performante pour la maîtrise des consommations énergétiques réelles des bâtiments. Cette thèse propose tout d’abord de développer des modèles polynomiaux de prédiction de la consommation énergétique tous usages en fonction des facteurs caractérisant l’intensité d’usage, la qualité d’usage et la qualité d’exploitation. Pour cela, nous utilisons le logiciel EnergyPlus afin de réaliser des simulations énergétiques dynamiques (SED) sur des valeurs de paramètres définis par la méthode des plans d’expérience D-optimaux. Le modèle polynomial créé permet alors d’effectuer, avec un faible temps de calcul, une propagation des incertitudes sur les consommations d’énergie calculées. Pour ce faire, nous utilisons les données mesurées en exploitation dans le cadre de la mesure et de la vérification de la performance énergétique, associées à une incertitude concernant leur valeur. Nous pouvons alors déterminer l’incertitude globale sur les consommations énergétiques et identifier les pistes pour la réduire, permettant ainsi un meilleur suivi et encadrement de la consommation énergétique réelle. / Since building envelope and MEP systems characteristics regularly improve, the weight of non-regulatory energy end-uses increases. These energy end-uses are typically associated with tenants or owners’ activities. In addition, high performance buildings show new issues related to HVAC systems operations. Therefore, it is important to evaluate and improve non-regulatory energy end-uses energy as well as HVAC systems operations efficiencies. We have developed polynomial energy models that can predict energy consumption as a function of building’s activities characteristics and HVAC systems operations factors. We used EnergyPlus software in order to build reliable energy models along with the D-optimum design of experiments method (DOE). Then, we used measurement and verification (M&V) data, associated with probability functions, to determine the associated uncertainty of the calculated energy consumption. Finally, we combine the latter with the polynomial modeling error to calculate the energy consumption global uncertainty, with the goal to identify strategies to reduce it.

Challenges of China’s sustainability : integrating energy, environment and health policies / Les défis de la soutenabilité en Chine : l'intégration des politiques de l'énergie, de l'environnement et de la santé

Yan, Huijie 06 December 2013 (has links)
Dans le but de faire face aux défis interdépendants en termes d’épuisement des ressources énergétiques, de dégradation environnementale et des préoccupations de santé publique dans le contexte chinois en réponse au développement durable, nous nous concentrons sur l'étude des politiques en matière d’énergie, d’environnement et de santé en Chine. Dans le chapitre 1, nous donnons un aperçu des politiques chinoises en matière d’énergie, d’environnement et de santé au cours des 20 dernières années afin de connaître les orientations politiques futures auxquelles le gouvernement n'a pas donné une attention suffisante. Dans les trois chapitres suivants, nous proposons une série d'études empiriques afin de tirer quelques implications politiques utiles. Dans le chapitre 2, nous étudions l'impact de l'urbanisation, de l'adaptation de la structure industrielle, du prix de l'énergie et de l'exportation sur les intensités énergétiques agrégés et désagrégés des provinces. Dans le chapitre 3, nous étudions les facteurs qui expliquent la transition énergétique vers des combustibles propres des ménages ruraux. Dans le chapitre 4, nous examinons les effets conjoints des risques environnementaux, du revenu individuel, des politiques de santé sur l'état de santé des adultes chinois. En particulier, nos résultats empiriques suggèrent d’intégrer le développement urbain dans la stratégie d'économies d'énergie; de considérer des substitutions/complémentarités complexes parmi les sources d'énergie et entre l'énergie et l’alimentation pour les ménages ruraux; d’aligner les politiques environnementales, énergétiques et alimentaires avec les politiques de santé. / With the purpose of coping with the intertwined challenges of energy depletion, environmental degradation and public health concerns in the Chinese-specific context in response to sustainable development, we focus on investigating China’s energy, environment and health policies. In chapter 1, we provide an overview of China’s energy, environment and health policies over the past 20 years in order to know about the future policy directions to which the government has not given a sufficient attention. In the following three chapters, we provide a series of empirical studies so as to derive some useful policy implications. In chapter 2, we investigate the impact of urbanization, industrial structure adjustment, energy price and export on provincial aggregate and disaggregate energy intensities. In chapter 3, we study the factors explaining the switches from dirty to clean fuel sources in rural households. In chapter 4, we examine the joint effects of environmental hazards, individual income and health policies on the health status of Chinese adults. Our empirical findings particularly suggest integrating urban development into the strategy of energy saving; considering the complex substitutions/complementarities among energy sources and between energy and food for rural households; aligning the environment, energy and food policies with health policies.
