Full textPurpose: The development of the present work, comprising the area of heat transfer and fluids mechanics involved analytical, numerical computational and experimental (in field environment) methods, with the purpose of analyzing the use of earth-to-air heat exchanger, as a strategy to reduce conventional energy consumption, for the heating or cooling of built environments. Thus, one of the study purposes was to evaluate, based on experimental results, the earth performance as an energy reservoir, derived from solar radiation incidence on the surface of the ground. We aimed, then, at identifying favorable parameters, procedures and conditions involving this strategy. The other study purpose was, using the GAMBIT and FLUENT softwares, computationally modeling the air flow in the earth-to-air heat exchanger. Method: The experimental and numerical study was preceded by the construction of a building, specially planned for the research, called Casa Ventura. As a follow-up, ducts were buried on the ground, to conduct external air and water (the latter one for a limited period) to the internal environment of the house. In terms of air conduction, the earth would work as an energy reservoir, heating or cooling the air. Concerning the water conduction, planned to use a duct of low thermal conductivity, the earth would only work as a protector from solar radiation, to preserve the water thermal characteristics, when flowing from the water reservoir, where it would be taken from, to the inside of the house. At Casa Ventura two central environments were built with similar dimensional and envelope characteristics, constituting the environments monitored in the process, in which, one in the natural and referential condition, without air renovation, and the other, with air renovation. In the experimental part, the air was captured from the external environment and inflated by a fan in the buried ducts, and it renovated the air inside this latter environment. With the help of a fan-coil, placed in this environment, the renovated air exchanged heat with the water flowing through the ducts. Due to some operational difficulties, the pumping of water lasted for a very short period. During the experiment, which lasted through the whole year of 2007, besides the water and earth temperature, the temperature and humidity of the following were also monitored and registered: the external air, the air in the internal environments and the air flowing in the buried ducts, as well as the flowing speed of the different fluids. Results: In a general way, the earth potential to heat was higher than the cooling of air injected in the buried ducts. The heating potential was higher in the months of May, June, July and August, doing so by more 3K. For depths between 2 and 3m, it is estimated that the potential might be over 8K. On the other hand, the potential for cooling was higher in the months of January, February and December, but it was low for low depths (less than a meter). For cooling, this potential may reach 4K. Research contributions: Considering the research results, several were the contributions, among which we highlight: the construction of an experimental database on the earth properties and characteristics (physical indexes, thermal diffusivity, volumetric heat capacity, thermal conductivity, temperature and humidity) and the environmental characteristics of the air (temperature and humidity) for the city of Viamão, located in Southern Brazil, and that may be used for the continuation of this research or for the elaboration of new researches and projects; and the development of a methodology for computational modeling of earth-to-air heat exchangers, validated through the experimental data mentioned before, enabling, therefore, the use of this numerical procedure for the elaboration of projects or new researches in this area.

Full textThis thesis deals with the thermal and energy analysis of a geothermal ventilated fonudation. Similarly to earth-to-air heat exchangers (EAHE) this foundation enables, according to the season, to preheat or to cool down the air for the hygienic air change. Considering the energy consumption constraints and the buildings users thermal comfort desire, these systems appears to be relevant. The principle of this foundation is simple: to force the air to circulate in a hollowed beam buried into the ground (1 to 3m depth) so that it takes advantage - via convection - to the thermal inertia of the ground. The difference lays on the fact that the channel is not a plastic or aluminium pipe but it a part of the building structure, namely the reinforced concrete foundation. This induces a significant space gain, usually devoted to the pipe burying. From a thermal point of view, the foundation exchanges heat with both the soil beneath the building, and with the soil exposed to the weather thermal loads. Furthermore, the depth - imposed by structural and economical purposees - is lower than that of traditional EAHE. In addition to the fact that concrete is a porous material, the humidity content may strongly influence the thermal performance of the foundation. The current work thus proposes to study the complex thermal behaviour of this foundation in two ways. The first is experimental: an retirement home equipped with two foundation has been intensively instrumented and data recorded over more than one year. The other is numerical: two models validated against the experimental data have been developed. The first is intended to be a designing tool, the second a tool to allow a fine comprehension of the physical phenomenon and take into account coupled heat and moisture transfers

Full textAs exigências da sociedade moderna e os seus hábitos estão a transformar o planeta Terra, desgastando os seus recursos naturais e poluindo os solos, a água e a atmosfera. O elevado ritmo de consumo energético, especialmente no sector da construção, tem levado a um intenso estudo de desenvolvimento e à utilização de energias renováveis com o objetivo de reduzi-lo até um nível sustentável. As Diretivas Comunitárias e a legislação portuguesa atualmente em vigor apontam para o aumento da eficiência energética dos edifícios, conseguindo-o através do aumento do isolamento térmico da envolvente, do melhoramento da estanquicidade ao ar dos envidraçados e da implementação de um mínimo horário de renovações do ar interior. No entanto, tem-se verificado que se com o aumento do isolamento da envolvente se conseguem reduzir os fluxos de calor entre o exterior e o interior, com a renovação de ar por hora aumenta-se as necessidades de aquecimento e por vezes de arrefecimento. Neste contexto, a utilização conjunta de sistemas de ventilação convencionais e de permutadores de calor com tubos enterrados no solo, pode trazer benefícios na redução dos consumos energéticos das necessidades de aquecimento e arrefecimento. Nestes sistemas, o ar insuflado é pré-aquecido ou pré-arrefecido ao circular nos tubos, dependendo da temperatura do ar em relação ao solo. Estas diferenças de temperatura podem atingir valores durante os picos de calor ou de frio, suficientes para reduzir significativamente ou eliminar a necessidade de equipamentos de aquecimento e arrefecimento. Tendo em conta que o referido sistema já foi alvo de variados estudos e é amplamente utilizado em vários países, pretende-se com este estudo a comparação direta entre os comportamentos térmicos de um edifício com e sem um sistema de tubos enterrados. Em adição, pretende-se estudar parametricamente a influência que os parâmetros de comprimento, diâmetro, profundidade e tipo de material dos tubos exercem na performance do sistema. Para isso, utilizar-se-á o programa de simulação energética “EnergyPlus” de modo a avaliar o desempenho da manutenção do conforto térmico num ambiente doméstico em várias zonas de Portugal.
The demands of modern society and its habits are changing the planet Earth, wearing out natural resources and polluting the soil, water and atmosphere. The high rate of energy consumption, especially in the construction sector, has led to an intense study, development and use of renewable energy in order to reduce it to a sustainable level. The Community Policies and Portuguese legislation currently in effect lead to an improvement of buildings' energy efficiency, achieving it by increasing thermal insulation of the external envelope, improving the air tightness of the glazing and the implementation of a minimum legal value of interior air changes per hour. However, it has been found that if with increased thickness of the surrounding insulation the heat flow between the inside and the outside is reduced, the imposed air changes per hour increase the energy consumption for heating and cooling. In this context, the joint use of conventional HVAC and earth-to-air heat exchanger systems can bring benefits in reducing energy consumption for heating and cooling. In these systems, the insufflated air is preheated or precooled, depending on the difference between the soil and air temperatures, when it flows through the buried pipes. These temperature difference can reach values, at the peaks of heat or cool, enough to significantly reduce or eliminate the need for heating and cooling equipment. Considering that this system has been the subject of various studies and is widely used in various countries, the aim of this study is the direct comparison of the thermal behaviour of a building with and without the buried pipes' system. In addition, it is intended to perform a parametrical study which determines the system's performance influence of parameters such as length, diameter, depth and pipes' material. For this, the energy simulation program "EnergyPlus" shall be used, in order to evaluate the thermal performance of the earth-to-air heat exchanger system applied in a residential environment in several places of Portugal.
