Abstract(s)
As piscinas exteriores aquecidas envolvem consumos de energia muito elevados, pelo que, encontrar soluções que permitam minimizar as perdas de energia através da envolvente e, em particular, pelo tanque, contribuirá de forma decisiva para a sustentabilidade destes equipamentos.
A presente dissertação tem por base o estudo de um sistema inovador de isolamento térmico pelo interior do tanque, com elevada durabilidade e manutenção reduzida, que permita diminuir as perdas de energia e consequentemente, as necessidades de aquecimento da água. O sistema em estudo explorou um conceito semelhante ao ETICS - External Thermal Insulation Composite Systems, frequentemente aplicado na envolvente exterior de paredes de edifícios com o propósito da melhoria do seu desempenho térmico, mas no caso das piscinas com reservas do ponto de vista do impacto a nível de estabilidade mecânica e por inerência da capacidade de impermeabilização nas piscinas.
O trabalho levado a efeito consistiu em estudos laboratoriais referentes a sistemas que incorporam placas de isolamento de diferentes materiais (face de avaliação e seleção do material), bem como a campanha experimental realizada no protótipo e em paredes de teste com placas de isolamento térmico ICB (Insulation Cork Board). Verificou-se que a solução desenvolvida apresenta resultados promissores no que respeita à capacidade de impermeabilização à água sob pressão, suscetibilidade à fissuração, resistência ao impacto e também no que se refere à resistência à aderência. Nesta fase, os resultados obtidos evidenciam um comportamento adequado face ao desempenho pretendido.
Heated outdoor swimming pools involve very high energy consumption, so finding solutions that allow minimizing energy losses through the surroundings and, in particular, through the tank, will make a decisive contribution to the sustainability of these equipment. The present dissertation is based on the study of an innovative thermal insulation system inside the tank, with high durability and low maintenance, which allows reducing energy losses and, consequently, the water heating needs. The system under study will explore a concept similar to the ETICS - External Thermal Insulation Composite Systems, often applied in the exterior coating of building walls with the aim of improving their thermal performance, but in the case of pools with reserves with mechanical stability and waterproofing capacity in swimming pools. The work carried out consisted of laboratory tests referring to systems that incorporate insulation boards of different materials (material evaluation and selection), as well as the results of the experimental campaign carried out on the prototype and on test walls with thermal insulation boards ICB. It was verified that the developed solution presents promising results in terms of waterproofing capacity to water under pressure, susceptibility to cracking, resistance to impact and also in terms of resistance to adherence. At this stage, the results obtained show adequate behaviour in relation to the intended performance.
