This study will address a form of duct design for a very specific pressurizing system: the pressurization of security staircases, used for evacuation and emergency in buildings, considered as a mandatory safety measure for some types of buildings in the state of Paraná - which by law prescribes the rules of fire and panic prevention that will also be used in this work. The standards delimit very specific pressure and flow conditions to be achieved without the use of complex dampers and electronic regulators on the stairs of each building floor generated by the air supply, but analyzing the design of the ducts and the boundary conditions stipulated by standard, intends to verify that the method of duct design known as static pressure recovery can be applied and it will be able to reach the specifications imposed by the prevention standards. Using data from literature, graphs and equations, experimental and empirical, a hypothetical project situation was created with quantitative values that represent the reality of the designers, using the static recovery method, serving as a demonstration of its applicability and constraints. In the method, the static pressure losses generated by the friction in the ducts were compensated by the energetic portion of the dynamic pressure. According to the results, it was observed that the method was efficient in the sizing of the pressurizing system ducts, adapting to the parameters imposed by the prevention regulations and the standards related to the duct sizing. However, it was verified that the amount of kinetic energy imposed in the system must be able to supply the energetic portion dissipated by the friction, which in certain scenarios will not be possible. |
