O presente trabalho enquadra-se na temática de segurança contra incêndio em edifícios e consiste num estudo de caso de projeto de deteção e extinção de incêndio num Data Center. Os objetivos deste trabalho resumem-se à realização de um estudo sobre o estado da arte da extinção e deteção automática de incêndio, ao desenvolvimento de uma ferramenta de software de apoio a projetos de extinção por agentes gasosos, como também à realização de um estudo e uma análise da proteção contra incêndios em Data Centers. Por último foi efetuado um estudo de caso.
São abordados os conceitos de fogo e de incêndio, em que um estudo teórico à temática foi desenvolvido, descrevendo de que forma pode o fogo ser originado e respetivas consequências. Os regulamentos nacionais relativos à Segurança Contra Incêndios em Edifícios (SCIE) são igualmente abordados, com especial foco nos Sistemas Automáticos de Deteção de Incêndio (SADI) e nos Sistemas Automáticos de Extinção de Incêndio (SAEI), as normas nacionais e internacionais relativas a esta temática também são mencionadas.
Pelo facto de serem muito relevantes para o desenvolvimento deste trabalho, os sistemas de deteção de incêndio são exaustivamente abordados, mencionando características de equipamentos de deteção, técnicas mais utilizadas como também quais os aspetos a ter em consideração no dimensionamento de um SADI. Quanto aos meios de extinção de incêndio foram mencionados quais os mais utilizados atualmente, as suas vantagens e a que tipo de fogo se aplicam, com especial destaque para os SAEI com utilização de gases inertes, em que foi descrito como deve ser dimensionado um sistema deste tipo.
Foi também efetuada a caracterização dos Data Centers para que seja possível entender quais as suas funcionalidades, a importância da sua existência e os aspetos gerais de uma proteção contra incêndio nestas instalações.
Por último, um estudo de caso foi desenvolvido, um SADI foi projetado juntamente com um SAEI que utiliza azoto como gás de extinção. As escolhas e os sistemas escolhidos foram devidamente justificados, tendo em conta os regulamentos e normas em vigor.
The present work is a case study of a project for detecting and extinguishing fire in a Data Center. The objectives of this work are summarized in a study on the state of the art Automatic Fire Detection and Automatic Fire Extinguishing Systems, the development of a tool to support projects for gaseous extinguishing agents, but also to conduct a study and an analysis of fire protection in data centers. Finally was made a case study. The objectives of this work are summarized in a study on the state of the art Automatic Fire Detection and Automatic Fire Extinguishing Systems, the development of a tool to support projects for gaseous extinguishing agents, but also to conduct a study and an analysis of fire protection in data centers. Finally was made a case study. Approach the concept of fire, where a theoretical study on the topic has been developed, describing how the fire may be originated and respective consequences. The national regulations regarding Fire Safety in Buildings are also addressed, with a special focus on Automatic Fire Detection Systems and Automatic Fire Extinguishing Systems, national and international standards for this subject are also mentioned. Because they are very relevant to the development of this work, the fire detection systems are thoroughly mentioned, the characteristics of detection equipment, the most used techniques as well as which aspects to consider in sizing an Automatic Fire Detection System. The most widely used extinguishing fire systems were mentioned, their advantages and what type of fire apply, with special emphasis on Automatic Fire Extinguishing System using inert gases. Data centers, being the object of study of this work, have a special focus on the characterization of these facilities, the importance of their existence and the general aspects that a fire protection should have, were mentioned. Finally, a case study was developed an Automatic Fire Detection System was designed along with a Automatic Fire Extinguishing System that uses nitrogen as the extinguishing gas. The choices and chosen systems were justified, taking into account the regulations and standards.
