Účinnost systémů plynového hašení v prostorech datacenter a lokální hašení chráněných prostor uzavřených rackových skříní

Abstract

The thesis focuses on evaluating the effectiveness of gas fire suppression in data centers, particularly targeting systems for local suppression of guarded areas. The introduction characterizes data centers, their purpose, classification, structure, specifications, operational, and design requirements. It further identifies fire safety and fire risks within data centers. Another section delves into the possibilities of fire suppression using gas-based fixed extinguishing systems. It compares local and volumetric suppression systems and specifies suitable systems for the local protection of rack cabinets. The final chapter of the theoretical section addresses the requirements and risks associated with operating these systems. The practical part of the thesis concerns an experimental test of local suppression, detailing the methodological procedure of the test, preparation, experiment execution, and subsequent evaluation. Another chapter in the practical section focuses on the mathematical modeling of the local gas fire suppression system and validates the model measurements. The conclusion of the thesis establishes technical requirements for installing local gas fire suppression in protected area within enclosed rack cabinets.
