Resumo(s)
A transição energética é apontada como uma das medidas apresentadas para o combate às
alterações climáticas, sendo necessário a procura por soluções energéticas mais "limpas",
acessíveis e eficientes. Soluções estas, tanto no lado da procura como no armazenamento
de energia.
O armazenamento de energia térmica, poderá ser uma solução. Os Phase Change Ma-
terials, (PCM´s) são capazes de absorver energia sob a forma de calor durante o processo
de mudança de fase.
Esta dissertação procura determinar a viabilidade da utilização de PCM para estabili-
zação de temperatura em parques de estacionamento. Para tal foram considerados quatro
casos de estudo, todos com caraterísticas distintas, um parque subterrâneo fechado, um
parque semi-aberto, um parque fechado não subterrâneo e a garagem de uma moradia.
Os diferentes perfis de cada cenário permitiram identificar algumas das condições ideais
para a utilização dos PCM. Os resultados obtidos permitiram determinar novos pontos a
ter em consideração para futuras aplicações de PCM. Entre estes, podemos distinguir que
a primeira etapa a considerar para a instalação de PCM será o estudo do comportamento
térmico do espaço, não só para definir a temperatura de mudança de fase ideal, mas para
garantir que os PCM’s serão capazes de realizar o processo de mudança de fase. Será ainda
necessário assegurar que a quantidade de PCM instalada é suficiente para assegurar a
estabilização de temperatura de todo o espaço.
The energy transition is pointed as one of the measures presented to combat climate change, being necessary necessary to search for "cleaner", more accessible and efficient solutions. These solutions, both on the demand side and on the energy storage. The storage of thermal energy could be one of these solutions. The Phase Change Materials, (PCM) are capable of absorving energy in the form of heat during the phase change process. This dissertation seeks to determine the viability of using PCM for temperature sta- bilization in parking spaces. For this, four case studies were considered, all with dif- ferent characteristics, one closed underground car park, a semi-open car park, a non- underground closed car park and the garage of a house.The different profiles of each scenario allowed us to identify some of the ideal conditions for the use of PCM’s. The results obtained allowed to determine new points to be taken into account for future PCM applications. Among these, we can distinguish that the first step to consider for the installation of PCM’s will be the study of the thermal behavior of the instalation space, not only to define the ideal temperature for the phase change, but also to ensure that the PCM’s will be able to carry out this phase change process. It will also be necessary to ensure that the quantity of installed PCM is enough for the temperature stabilization of the entire space.
