Abstract(s)
O presente documento tem como principal objectivo efectuar o projecto de dimensionamento de um sistema de águas quentes sanitárias para uma escola.
Numa primeira fase foi elaborado uma pesquisa sobre o contexto energético, a nível mundial, europeu e nacional, bem como o seu contexto jurídico a nível europeu e nacional, e uma explicação superficial sobre os fundamentos da energia solar, onde se foca a importância da radiação solar e os vários tipos de sistemas solares térmicos, bem como os seus constituintes.
Segue-se a abordagem ao caso de estudo onde foram efectuados inicialmente inquéritos como forma de determinar os consumos de água quente utilizada nessa escola.
Continuou-se o estudo efectuando-se a variação de duas características do sistema solar: o tamanho dos depósitos e o tipo de colectores solares a aplicar.
Após as simulações efectuadas para a determinação das soluções a aplicar ao sistemasolar e apresentadas ao longo do presente documento, foram efectuadas análises económicas como forma de se verificar a viabilidade do sistema a aplicar.
Por último foram elaboradas conclusões sobre o sistema a aplicar e apresentados alguns cenários financeiros do mesmo.
The present document has as main objective to make the draft design of a hot water system for a school. Initially a research was developed at energy context, global, European and national levels, as well as the legal context, European and national level. Also there is a brief explanation about the basics of solar energy, which focuses on the importance of solar radiation, with various types of solar thermal systems, and also explanations of the main components of the solar thermal system. The next item is the approach in the case study questionnaire the school in order to determine the consumption of hot water used. The study was continued by performing the variation features of two of the solar system: the size of deposits, and the type of solar collectors to be applied. After the simulations to determine the components of the solar system to be applied, na economic analysis was performed in order to verify the feasibility of the system. Finally conclusions were drawn about the system to be implemented and then presented some financial scenarios of the system to be applied.
