 Smoke extraction affects the processes of safe evacuation of people from the building. There are regulations that state that in certain rooms it is necessary to provide for the removal of gorenje products for the safe evacuation of people. Gorenje products are removed in the upper part of the room, and compensating air is supplied in the lower parts. Smoke extraction can be natural due to the transoms of mostly single-storey buildings, it can be mechanical, that is, removed by roof-mounted, radial smoke extraction fans. The design of smoke extraction affects all people, necessarily people with limited mobility. Special events are planned for low-mobility groups of the population. There are many techniques in the smoke extraction design process. We use the latest developed fire techniques of the All-Russian Research Institute of Fire Protection. Smoke extraction occurs from corridors, shopping malls, atriums, passages, offices, industrial premises, parking lots, etc. Compensation, air supply to the vestibule-locks, stairwells of non-smokable type H2, halls, lobbies. The air compensation must not exceed the exhaust air consumption by 30%. We cooperate with a well-known and reliable manufacturer of VESA equipment. There is also a Russian manufacturer KORF. This product falls under the import substitution program. There are Korf families for Revit. We also cooperate with fire experts, which will allow us to easily coordinate the installed smoke extraction system of the building with the supervisory authorities. Some standards of the smoke extraction system can be seen here. Even if ventilation systems and fire protection systems are agreed upon, the smoke extraction system is the main importance here. The current smoke extraction calculation software can be downloaded here.

Linear elongation compensators are used for smoke extraction ducts at temperatures of 300,400 degrees and above. In residential buildings, expansion joints are designed for 3-4 floors. The calculation formula is as follows: dL=k*L*dt k is the coefficient of linear expansion, L is the length of the clamped section, dt is the temperature difference m/y by the indoor air temperature during installation and operation. where k= carbon steel (10-17)*10^(-6)
