Abstract

System różnicowania ciśnienia na pionowych drogach ewakuacyjnych zawierający wentylator napowietrzający, miernik ciśnienia, układ automatyki regulujący ciśnienie charakteryzuje się tym, że zawiera klapę (2) do rozszczelnienia obudowy drogi ewakuacyjnej zamontowaną w drzwiach ewakuacyjnych, przy czym powierzchnia czynna klapy (2) wyznaczana jest indywidualnie dla każdego obiektu według wzoru: A = (0,715 x V<sub>max</sub>)/√Δ, A[m<sup>2</sup>] — powierzchnia rozszczelnienia, Δp[Pa] — różnica ciśnień pomiędzy pionową i poziomą drogą, V<sub>max</sub> [m<sup>3</sup>/s] — znamionowy wydatek wentylatora zastosowanego w systemie różnicowania ciśnienia.The pressure differential system on vertical escape routes, including an air ventilator, a pressure gauge, and a pressure-regulating automation system, is characterized by a flap (2) for unsealing the escape route housing installed in the escape door, while the active surface of the flap (2) is determined individually for each object according to the formula: A = (0.715 x V <sub> max </sub>) / √Δ, A [m <sup> 2 </sup>] - leakage area, Δp [Pa] - pressure difference between vertical and in a horizontal way, V <sub> max </sub> [m <sup> 3 </sup> / s] - rated flow of the fan used in the pressure differential system.
