An Summary of Mechanical Smoke Ventilation and How It Works
Mechanical smoke ventilation is an effective smoke control technique that defends the staircase from smoke ingress. The look of mechanical ventilation systems ensure security to the stairs and stop wind and create stack result. Stack result allows smoke to visit up the building instead of filling an area with combustion gases. Through the Aksaray fire incident, the fire-squad reached on web page promptly. On the other hand, the dense smoke from the fire hindered the fire-squad efforts to support the fire and prevent harm. The smoke was too dense such that tries to suck it employing fans failed. Mechanical smoke ventilation must have prevented extreme destruction of the Aksaray Shopping mall by giving specified extraction rates, little wind sensitivity, decreased shaft cross sections and high capability to avoid system resistance. Living of the mechanical smoke ventilation would have taken care of a stratified smoke layer within the corridor of the retail center and hindering smoke from getting into the stair. The Aksaray fire incident was essential since the mall was based mostly underground which means that natural ventilation smoke control techniques wouldn't normally been employed by efficiently. The pressurization and depressurization characteristic of the mechanical smoke ventilation would have furnished tenable environment inside Aksaray mall. Depressurized corridor scheme could have hindered smoke from spreading in to the stair and allowed smoke stratification within the corridors of the retail center (Svensson 2000, P.37-38).
