Due to the economic booms, power demand has been increasing significantly in Taiwan, and become the main cause for power shortages. Therefore, building energy conservation has become the major strategy in cope with the national energy policy. However, the building energy code has provided only a flat threshold value for specific building type, and lacking of diversity among building sizes and various weather conditions. It is the goal of this study to further classify this threshold value, by conducting full-scale experiment on energy consumption in hotel buildings across the country. Among the 29 hotel buildings selected ,the EUI and DUI values were measured and recorded annually, and compared with the DOE 2.2 simulation results. The comparative study further analyzed the primary factors in affecting the EUI and DUI values, including weather conditions, building sizes, such as floor area, and hotel rankings. The detailed classification of the hotel building energy consumption threshold values can be adapted as effective design criteria or building energy codes and standards which can contribute significantly.

Dairy farmers suffered substantially increased energy bills during the 1970's, at a time of herd expansion and modernisation of equipment to allow bulk milk refrigeration and storage on the farm. Little was known of the levels of electricity use in the dairy farming sector, but extrapolations had suggested a figure of 300 to over 400 kWh/cow/annum. Farmers were requesting quantitative estimates for the potential of conservation equipment, particularly plate heat exchangers and heat recovery units. An energy audit of dairy farms in South Devon is described. Over a period of two years, data were collected relating to energy use by each of the major components of a milking parlour and dairy, for a range of parlour sizes, levels of production and the ambient conditions. Analysis revealed the factors most influencing variations in energy use. An equation was developed to describe the energy use by a bulk milk tank, given the level of production and the ambient temperature. The bulk tank accounted for some 40% of the total energy used. The bulk tank has been studied in detail. The stages of heat transfer from the milk to the chilled water and the resulting effects upon the ice bank have been modelled. Laboratory investigations were carried out to determine some parameters empirically. The model's limits, sensitivity and validation are reported. Typical levels and ranges of energy use are suggested. A mean of approximately 250 kWh/cow/annum resulted from the audit, but 200 kWh/cow/annum was achieved by the most economical of farms without resort to conservation equipment, and this level is proposed as a target for the conscientious farmer. The factors affecting energy use in the farm dairy are identified as political, environmental, technical and managerial and these are discussed. The farmer's influence has to be directed mainly at the last of these categories. Investment in energy conservation equipment should not be considered until consumption is down to the proposed target level.

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
