Abstract(s)
A partir de um sistema de ar condicionado tipo aplicável a hotéis, pretende obter-se a solução de parâmetros de funcionamento deste sistema considerada ótima, em termos de consumo energético. Para o efeito, analisar-se-á um conjunto de soluções tecnicamente possíveis, para a climatização de um edifício hoteleiro. A solução ótima de uso de energia pode obter-se da avaliação de todas as hipóteses possíveis, sem que seja necessário testar todas as combinações das variações de parâmetros do projeto em causa. Na realidade, o planeamento de experiências e o método Taguchi permitem obter a solução ótima, estudando apenas um conjunto bem definido das hipóteses referidas. A realização deste trabalho terá as seguintes três fases. Primeiramente classifica-se o conceito NZEB, explicando as diversas noções a este referentes. É também realizado um enquadramento legal dos conceitos com as regulamentações em vigor. Posteriormente é modelado um edifício que será validado com base em auditoria de campo. Este modelo é posteriormente utilizado para quantificar os usos de energia das diversas combinações de parâmetros tecnológicos, fisicamente possíveis. Tal modelação será baseada num modelo do edifício já elaborado por uma equipa certificada de auditória. Esta modelação e a posterior simulação são realizadas com recurso ao software de simulação Hourly Analysis Program. Para obter os resultados pretendidos será selecionado um tipo de sistema de climatização capaz de ter um reduzido uso de energia, simulado com o modelo validado. Com este sistema, e aplicando o planeamento de experiências, pretende obter-se a solução mais viável em termos energéticos. Para o efeito serão feitas as combinações de fatores necessárias e de acordo com a metodologia de Taguchi é obtida a solução ótima.
From a standard system applicable to hotels it is desired to obtain the optimal solution of parameters of this system. For this purpose, a set of technically possible solutions will be analyzed for the air conditioning of a hotel building by varying the physical parameters. The optimal energy-use solution can be obtained from the evaluation of all possible ways, without the need to test all combinations of the parameter variations of the project in question. In fact, Experiment Planning and the Taguchi method allow us to obtain the optimal solution, by studying only a well defined set of all possible ways mention before. The accomplishment of this work will have the following three stages. First, a study and a theoretical approach to the NZEB concept are carried out. A legal framework of the concepts is also carried out with the regulations in current law. After, a building is modeled and will be validated through the energy simulation process. This model will later be used to quantify the energy uses of the various combinations of technological parameters. This modeling will be based on a building model already prepared by a certified audit team. This modeling and the referent simulation will be performed using a simulation software denominated Hourly Analysis Program. To obtain the final results, a type of air conditioning system capable of having a low energy use will be selected, and after it is simulated with the validated model. With this system, and applying the design of experiments, will be sought the most viable energy solution. For this purpose, the number of the necessary factor combination will be made and according to the Taguchi methodology will be obtained the optimal solution.
