Повний текст джерелаLos edificios suponen una fracción significativa del consumo energético y de emisiones de CO2 globales. Resolver este problema requiere implementar tecnologías de eficiencia energética e integrar energías renovables. En este contexto, los muros radiantes son una tecnología capaz de lidiar con estos retos. La evaluación del potencial del sistema se ha llevado a cabo con la experimentación de un cubículo con muros radiantes conectados a un sistema geotérmico. Los resultados muestran la capacidad del sistema para reducir el consumo energético y desplazar los picos de demanda, destacando también la sensibilidad a los parámetros de control. Los datos experimentales sirvieron para desarrollar un modelo numérico del muro radiante, el cual se ha usado para un estudio paramétrico de los parámetros de diseño. Finalmente, este se ha integrado a un modelo de cubículo para estudiar diferentes conceptos de control que maximicen el aprovechamiento de la producción de unos paneles fotovoltaicos.
Buildings represent a significant fraction of the global energy use and CO2 emissions. Solving this issue require the implementation of energy efficiency technologies and the integration of renewable energies. In this context, radiant walls are a technology capable of dealing with these challenges. The evaluation of this system was carried out with the experimentation of a radiant wall cubicle coupled to a geothermal system. The results showed the capability of the system for reducing the energy and shifting the peak loads, highlighting the sensitivity to control parameters. The experimental data was used for the development of a numerical model of the radiant wall, which was used in a parametric study of the design parameters. Finally, the numeric model was integrated in a cubicle model in order to study different control concepts that maximized the use of the energy produced by photovoltaic panels.

Повний текст джерелаLa qualité thermique des bâtiments modernes a une tendance à se détériorer en raison de considérations esthétiques et économiques. L'utilisation de matériaux de construction de bon marché et thermiquement inappropriées ne cesse d'augmenter dans les nouvelles constructions. À l'heure actuelle, la conception architecturale a changé. L'orientation est peu étudiée, la hauteur intérieure des nouveaux locaux est faible comparée à celle de la maison traditionnelle et le patio est remplacé par un couloir. Les différentes parties sont devenues communicantes. Ainsi, l'espace de chauffage et de refroidissement devient plus important. L'habitation traditionnelle tunisienne présente une architecture bioclimatique qui permet de fournir un confort minimal naturellement. Notre travail vise à exploiter le REVIT dans la simulation des bâtiments résidentiels en Tunisie et d'optimiser le modèle d'habitat moderne. Après validation des résultats obtenus par REVIT, comparés à ceux de TRNSYS et SPREADSHEET ASHRAE, nous l'avons, tout d'abord, exploité pour évaluer les deux modèles d'habitats (traditionnels et contemporains). Les résultats d'évaluation, en utilisant REVIT, montrent que l'habitat traditionnel sont plus efficaces que celui moderne particulièrement en période estivale. Par la suite, nous avons optimisé le modèle de maisons contemporaines, en utilisant en premier lieu, les stratégies passives de l'architecture bioclimatique traditionnelle, et en second lieu, en utilisant les mesures d'amélioration utilisées dans des études antérieures. Afin, de déterminer une variante de modèle d'habitat contemporain thermiquement optimal et qui s'intègre dans le climat méditerranéen, plusieurs tests sont générés en utilisant REVIT. Ces tests montrent l'efficacité de ce dernier qui se base sur la méthode RTS dans la simulation thermique des bâtiments résidentiels.

Повний текст джерелаAn analytical model has been developed to predict the panel temperature and heat output for perimeter radiant panel systems with a known inlet temperature and flow rate, based on a flat plate solar collector (RSC) model. As radiative and convective heat transfer coefficients were required to run the model, an analytical analysis of the radiative heat transfer was performed, and a numerical model was developed to predict the convective heat transfer coefficient. Using the conventional radiative heat exchange method assuming a three-surface enclosure, the radiative heat transfer could be determined. Numerically, a correlation was developed to predict the natural convective heat transfer.
To validate the analytical model, an experimental analysis was performed on radiant panels. A 4m by 4m by 3m test chamber was constructed in which the surrounding walls and floor were maintained at a constant temperature and the heat output from an installed radiant panel was measured. Two radiant panels were tested; a 0. 61m wide panel with 4 passes and a 0. 61m wide panel with 8 passes. The panels were tested at 5 different inlet water temperatures ranging from 50°C to 100°C.
The RSC model panel temperature and heat output predictions were in good agreement with the experimental results. The RSC model followed the same trends as that in the experimental results, and the panel temperature and panel heat output were within experimental uncertainty, concluding that the RSC model is a viable, simple algorithm which could be used to predict panel performance.

Low lift cooling systems (LLCS) hold the potential for significant energy savings relative to conventional cooling systems. An LLCS is a cooling system which leverages existing HVAC technologies to provide low energy cooling by operating a chiller at low pressure ratios more of the time. An LLCS combines variable capacity chillers, hydronic distribution, radiant cooling, thermal energy storage and predictive control to achieve lower condensing temperatures, higher evaporating temperatures, and reductions in instantaneous cooling loads by spreading the daily cooling load over time. The LLCS studied in this research is composed of a variable speed chiller and a concrete-core radiant floor, which acts as thermal energy storage. The operation of the chiller is optimized to minimize daily energy consumption while meeting thermal comfort requirements. This is achieved through predictive pre-cooling of the thermally massive concrete floor. The predictive pre-cooling control optimization uses measured data from a test chamber, forecasts of controlled climate conditions and internal loads, empirical models of chiller performance, and data-driven models of the temperature response of the zone being controlled. These data and models are used to determine a near-optimal operational strategy for the chiller over a 24-hour horizon. At each hour, this optimization is updated with measured data from the previous hour and new forecasts for the next 24 hours. The novel contributions of this research include the following: experimental validation of the sensible cooling energy savings of the LLCS relative to a high efficiency split system air conditioner - savings measured in a full size test chamber were 25 percent for a typical summer week in Atlanta subject to standard efficiency internal loads; development of a methodology for incorporating real building thermal mass, chiller performance models, and room temperature response models into a predictive pre-cooling control optimization for LLCS; and detailed experimental data on the performance of a rolling-piston compressor chiller to support this and future research.

Повний текст джерелаAstra Zeneca plant in Gärtuna has many compression cooling machines for comfort that consume about 11.7 GWh of electricity per year. Many of the cooling machines are old; due to the increase of production of the plant, cooling capacity was limited and new machines have been built. Now, the cooling capacity is over-sized. Söderenergi is the district heating plant that supplies heating to Astra Zeneca plant. Due to the strict environmental policy in the energy plant, last year, a bio-fuelled CHP plant was built. It is awarded with the electricity certificate system.
The study investigates the possibility for converting some of the compression cooling to absorption cooling and then analyzes the effects of the district heating system through MODEST optimizations. The effects of the analysis are studied in a system composed by the district heating system in Södertälje and cooling system in Astra Zeneca. In the current system the district heating production is from boiler and compression system supplies cooling to Astra Zeneca. The future system includes a CHP plant for the heating production, and compression system is converted to absorption system in Astra Zeneca. Four effects are analyzed in the system: optimal distribution of the district heating production with the plants available, saving fuel, environmental impact and total cost. The environmental impact has been analyzed considering the marginal electricity from coal condensing plants. The total cost is divided in two parts: production cost, in which district heating cost, purchase of electricity and Emissions Trading cost are included, and investment costs. The progressive changes are introduced in the system as four different scenarios.
The introduction of the absorption machines in the system with the current district heating production increases the total cost due to the low electricity price in Sweden. The introduction of the CHP plant in the district heating production supposes a profit of the production cost with compression system due to the high income of the electricity produced that is sold to the grid; it profit increases when compression is replaced by absorption system. The fuel used in the production of the future system decreases and also the emissions. Then, the future system becomes an opportunity from an environmental and economical point of view. At higher purchase electricity prices predicted in the open electricity market for an immediately future, the future system will become more economically advantageous.

Повний текст джерелаGurjer, Yeshwant Ramesh. Use of Heat Pumps for Heating and Night Cooling of Greenhouses. (under the direction of Daniel H. Willits). The use of heat pumps for heating and night cooling of greenhouses was investigated using a computer simulation program and weather data from Typical Meteorological Year (TMY2) datasets for Raleigh, NC, and Wilmington, NC. A greenhouse computer model taken from the literature, along with the heat pump subroutines (HPHEAT and HPCOOL) developed in this study, were used for the simulations. The use of heat pumps for heating only, and for heating plus night cooling, were examined separately using both standard and time-of-use electricity rates for two North Carolina utility providers. When heat pumps were used only for heating, standard electricity rates were predicted to provide greater savings in utility costs compared to time-of-use rates. When heat pumps were used for both heating and night cooling, the predicted savings in utility costs was greater for time-of-use electricity rates. Night cooling was predicted to decrease the average daily temperature (0.10C to 1.10C) and average nighttime temperature (0.10C to 2.00C) inside the greenhouse providing the potential for increased yield. Although a heat pump of capacity 36.5 W/m2 of floor area provided less savings in total costs compared to a capacity of 76 W/m2, the heat pump with the smaller capacity (36.5 W/m2) may be a better proposition because of the lower purchase cost.

Повний текст джерелаSistemas condicionadores de ar automotivos têm sido extensivamente estudados, buscando melhor eficiência de resfriamento e redução do consumo de combustível. O presente trabalho tem como objetivo o estudo de um sistema condicionador de ar automotivo operando nos modos de resfriamento e aquecimento, este último atendendo às necessidades de conforto em dias frios nos veículos elétricos, os quais não apresentam calor de rejeito do motor, como nos veículos convencionais. Para tal foi projetado e montado, no Laboratório de Refrigeração, Condicionamento de Ar e Criogenia da PUC-Rio, um aparato experimental composto por duas câmaras de temperatura e umidade controladas, uma simulando o compartimento de passageiros e a outra, o ambiente externo. Um típico sistema condicionador de ar automotivo, composto por componentes comercialmente disponíveis e utilizados nos veículos atuais, foi dotado de válvulas direcionais, permitindo a inversão do ciclo de compressão de vapor do modo de resfriamento para o modo de aquecimento, operando neste último como bomba de calor. Dados experimentais foram levantados sob operação em regime permanente e transiente (período de partida), com temperaturas entre – 5 graus Celcius e 45 graus Celcius. Para o modo de resfriamento, seguiu-se a norma SAE J2765 e, para o de aquecimento, na ausência de normas, foram cobertas as operações em modos de recirculação do ar da cabine e de renovação com ar externo, entre as temperaturas de -5 graus Celcius e 10 graus Celcius. Foi também realizada uma simulação numérica, validada pelos dados experimentais, utilizando as equações fundamentais da termodinâmica e transferência de calor. O sistema testado mostrou-se viável na aplicação em veículos elétricos, uma vez que nestes o calor de rejeito previsto (regeneração de frenagem e efeito Joule na eletrônica de potência) não é suficiente para o conforto térmico em dias frios. Demonstrou-se que a bomba de calor consome menos energia que resistências as elétricas atualmente utilizadas.
Automotive air conditioning systems have been extensively studied, searching for better cooling efficiency and reduced fuel consumption. The present work aims to study a system of automotive air conditioner operating in cooling and heating modes, the latter satisfies the needs of comfort on cold days in electrical vehicles, which do not include waste heat from the engine as the conventional vehicles. To this was designed and assembled in the Refrigeration, Air Conditioning and Cryogenics Laboratory, in Puc-Rio, an experimental apparatus consists of two chambers with temperature and humidity controlled, one, simulating the passenger compartment and the other, the external environment. A typical automotive air conditioning system, composed of commercially available components used in current vehicles is provided with a directional valve, allowing the inversion of vapor compression cooling mode to the heating mode cycle, the latter operating as a heat pump.
