Abstract(s)
No âmbito do curso de Mestrado em Engenharia Mecânica foram abordados uma série de temáticas
focando os sistemas energéticos de Aquecimento, Ventilação e Ar Condicionado (AVAC) em
edifícios. Deste modo, foi natural o interesse em desenvolver um projeto na área do AVAC tendo a
escolha recaído no refeitório do Universidade do Algarve no Campus da Penha em Faro.
Os refeitórios são espaços com especificidades próprias e com requisitos de conforto térmico e de
qualidade do ar interior que os tornam grandes consumidores de energia. Assim o
dimensionamento dos sistemas de AVAC de um edifício deste tipo são um aspeto importante e
atual.
O presente projeto teve por objetivo dimensionar os sistemas de AVAC do refeitório, constituído
pela zona de refeições e pela cozinha industrial acima referido abordando as várias fases de
elaboração de um projeto de execução AVAC.
Numa fase inicial foi feito o levantamento do edifício e de toda a envolvente, tal como os volumes
a climatizar, áreas de envidraçados, paredes, coberturas, pavimentos, equipamentos, ocupação e
respetivos materiais de construção onde posteriormente foram calculadas as cargas térmicas
utilizando o programa de modelação CYPETM. Posteriormente, conhecidas cargas térmicas para cada
espaço diferenciado pela sua utilização, foram dimensionados os sistemas de climatização. Além
disso foram também abordados os sistemas de ventilação e controlo de fumos para manter a
qualidade do ar interior.
Por fim, foram elaborados os desenhos de execução do projeto implantando os vários sistemas AVAC nas plantas do edifício e efetuado o mapa de trabalhos e quantidades dos materiais.
Under the scope of the Master's degree in Mechanical Engineering, a series of themes were addressed focusing on the heating, ventilation and air conditioning (HVAC) energy systems in buildings. Thus, it was a natural interest to develop a project in the HVAC area where the choice relapsed on the University of Algarve’s dining hall at the Campus da Penha in Faro. Dining halls are spaces with their own specificities and with requirements of thermal comfort and indoor air quality that make them large energy consumers. Thus the HVAC systems sizing on a building like this is an important and current aspect. The present project aimed to calculate the HVAC systems of the refectory, consisting of the dining area and the industrial kitchen referred to above, addressing the various stages of preparation of a HVAC implementation project. In an initial phase, the building and all the surrounding area were surveyed, as well as the volumes to be air conditioned, glazed areas, walls, roofs, floors, equipment, occupation and respective building materials, where thereafter the thermal loads were calculated using the program. CYPETM. Subsequently, known thermal loads for each space differentiated by its use, the climatization systems were dimensioned. In addition, ventilation and smoke control systems were also addressed to maintain indoor air quality. Finally, the project execution drawings were drawn up by implementing the various HVAC systems in the construction plans and carried out or the work map and material items.
