This thesis covers the design and simulation of the impulse mechanical ventilation system of the underground parking lots of a multi-family building; this as a proposal for improvement over the existing traditional mechanical ventilation system in the study building. The design of this thesis involves, on the one hand, the use of current national and international standards such as EM.030 [1], UNE 23585 [2] and BS 7346- 7 [3] and the use of the recommendations from associations such as ASHRAE ([4] and [5]), and NFPA [6]; and, on the other hand, the realization of the separate bones to obtain the flow rates and pressure losses in order to select the equipment and accessories. After the proposed design, the design of this ventilation system is optimized through CFD simulations with SimScale, whose configurations require calculations based on the regulatory requirements and recommendations of the aforementioned associations. Finally, through the results of the CFD simulations, the operation of the two mechanical ventilation systems is evidenced both when they operate in normal mode and when they operate in emergency mode. Chapter I, which corresponds to the introduction, presents the study building, details the objectives of this work and its scope. Chapter II contains the theoretical foundations and technical standards that support comprehensive design calculations and equipment selection. Chapter III shows the engineering calculations and the use of the ASHRAE Duct Fitting Database to design the impulse ventilation system, which is made up of two injection networks and one extraction network. Chapter IV details the selection of equipment and accessories based on current regulations and their technical characteristics calculated in the previous chapter. Chapter V focuses on explaining the concepts, setups, and calculations required to run CFD simulations; in such a way that this chapter acts as a tutorial for the simulations of the types and modes of mechanical ventilation of underground car parks. Chapter VI shows the results of the CFD simulations of the existing traditional system and the optimized proposed impulse system, both when they operate in normal mode and in emergency mode, and then analyze their results. Chapter VII presents the cost structure of the proposed design, since it is a requirement for the approval of its installation in the described building. Finally, the respective Conclusions, Recommendations and the Bibliographic Reference that support this thesis are presented.
