Modelagem teórico-experimental de sistemas suspensos de secagem doméstica de vestuários /Ribeiro, Jefferson Almeida. January 2002 (has links)
Orientador: Paulo Magalhães Filho / Banca: João Andrade de carvalho Júnior / Banca: José Nedilo carrinho de Castro / Banca: Pedro teixeira Lacava / Banca: Marco Aurélio Ferreira / Resumo: Com a evolução tecnológica e maior competitividade entre as empresas, aliadas as maiores exigências do mercado consumidor, tornou-se imprescindível, na avaliação e aceitação de secadoras, a necessidade de se fabricar equipamentos que operem com maior rendimento e menor consumo de energia. Tais fatos motivam a estudar e analisar o desempenho de sistemas suspensos de secagem de uso doméstico, com relação às características de funcionamento e eficiência no processo de desumidificação de tecidos, pois os parâmetros que influenciam o desempenho dos secadores e os mecanismos de secagem devem ser conhecidos nos graus de precisão requeridos para cada aplicação. Os parâmetros avaliados neste trabalho foram os seguintes: conteúdos de umidade do tecido na entrada e na saída do secador, condições de transferência de calor, temperatura, a velocidade, a direção e a umidade absoluta do fluxo do meio de fornecimento de calor, e a distribuição de temperatura superficial do tecido. As previsões teóricas são comparadas com os resultados experimentais obtidos em uma bancada de testes onde, conforme configurações apresentadas, simularam-se as condições reais de trabalho do sistema. Foram selecionados os tecidos mais utilizados para manufatura de vestuário: Jeans índigo, Flanela, Cotton-Lycra, Brim, Tergal, Viscose e Linho. / Abstract: Due to the technologic evolution and a higher competition among the companies, with the bigger requirements of the consuming market, it turned out necessary the manufacturing of equipment with higher performance and lower energy consumption. These aspects are motivation for studying and analyzing the performance of suspended household drying systems, regarding to their functioning features and efficiency on the cloth dehumidification process, since the parameters which influence the dryer performance and the drying mechanisms must be well known on the required accuracy degrees for each application. The parameters evaluated by this thesis were: cloth moisture contents at the dryer input and output; heat transfer conditions; speed, direction and absolute humidity of the heat supplying mean; and the cloth surface temperature distribution. The theoretical predictions are compared to the experimental results obtained from a test bench, where real system work conditions were simulated. The most utilized kinds of cloth for clothing manufacturing were selected, such as: blue-jeans, flannel, cotton-spandex, canvas, polyester, viscose rayon and linen. / Doutor

Factors affecting the energy consumption of data centres in South AfricaYoung, Daleela 17 March 2010 (has links)
Companies in the US and the UK are frantically looking for ways to prevent future exorbitant data centre costs. South Africa does not have the space shortages, nor the high energy costs that companies in the US and UK experience. Hence, data centre energy efficiency is currently not a priority for South African businesses. However, things are about to change. Rising electricity costs and high growth rates in electricity consumption will motivate companies to consider implementing energy efficiency initiatives in their data centres. The purpose of the research begins at an assessment of the level of awareness of the energy consumption of data centres. This report looks at what the perceptions are of the factors that could cause fluctuations in energy usage at the data centre. The report further explores how South African companies are addressing potential fluctuations in usage, and what the motivation is for action taken. The methodology was a series of telephonic, semi-structured interviews with available and relevant stakeholders in data centre energy management. The interviewees were sourced from ICT companies in South Africa identified by the Market Research Foundation in the publication “Top ICT companies in South Africa 2005/6”, attendees of the ITWEB Green IT Summit 2008, and further referrals from these interviews. / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

Recommended changes for knee wall insulation practices to increase energy efficiencySprague, Jill January 2005 (has links)
This paper explains typical knee wall construction and insulation in homes in Indiana and demonstrates the energy inefficiencies caused by such methods. Literature research gives examples of possible opportunities for changing the standard methods of knee wall construction and insulation. The methodology of the study is explained, as is energy intensity (EI) — the main evaluation tool used in this paper. EI allows a researcher to compare homes of different sizes in different locations. Overall, the study shows that homes whose knee walls have an air barrier backing use less energy than homes without knee walls. Additionally, as expected, homes with improperly constructed knee walls use the most energy. Finally, the paper contains recommendations about what methods might be used to change the standard practices involved in building and insulating knee walls. / Department of Urban Planning
