Summary
Three ways to supply air to a tall stair: single injection at the top, multiple injection through a duct, and a stair divided into compartments. Based on Klote (2002), pp. 4-286 and 4-287.
Original vector illustration for Stair pressurisation, level 2 Intermediate.
- Source basis: Klote (2002), p. 4-286 (single injection, loss of air through open doors near the injection point), p. 4-287 (multiple injection with fan at ground level or roof; compartmentation with at least one injection point per four-floor compartment; Figures 4-12.15 to 4-12.17, redraw, do not copy)
- Alt text: Three stair cross-sections: one with a single roof fan, one with a duct feeding air at several floors, one divided into sections each with its own supply.
