Abstract
In my thesis I am writing about automatic fire extinguishing systems and the creation of a project assignment for fire extinguishing of a server centre.
I start the thesis with an introduction to fire and the basics of combustion. The most common causes of fire are described, as well as the development of the fire in the different phases along with explanations of each phase of the fire.
This is followed by an introduction to automatic fire extinguishing systems, where I in detail explain the differences between conventional and addressable fire detector technology, the different types of detectors and their scope of application. Followed with list of most common extinguishing agents and their extinguishing properties.
In the project part, the technical solution for automatic fire extinguishing of the selected server centre is presented. The electrical part of the project comprises the design of the fire detection system, the electrical installations, and the selection of the appropriate fire detection equipment. In the mechanical part of the project, I have selected the NOVEC 1230 fire extinguishing agent and drawn up an isometric diagram of the extinguishing pipeline with the locations of the nozzles. I also used the Siemens hydraulic calculation tool for the extinguishing system to obtain data on nozzles, pipe cross-sections, extinguishing agent quantity and overpressure relief.
