Pressurized Elevator Shaft Smoke Control System

he Pressurized Elevator Shaft Smoke Control System utilizes vertical ducts in emergency/evacuation elevator shafts to pressurize the air within the elevator shaft,
serving as a smoke control system. Compared to traditional vertical duct methods,
the Elevator Shaft Pressurization System offers increased floor space efficiency,
contributing to enhanced spatial utilization. Additionally,
it leads to significant cost savings as there is no need for vertical duct construction.
The Elevator Shaft Pressurization System is a multidisciplinary technology that goes beyond firefighting considerations,
encompassing aspects of architecture, electrical engineering, structure, and elevator systems.
Comprehensive evaluations are essential to implement this technology effectively.

Criteria for Applying the Elevator Shaft Pressurization System

  • The system pressurizes the interior of emergency/evacuation elevators using vertical airflow within the elevator shaft.
    - Emergency Elevators: According to NFSC 501A, Article 16 (Pressurization) of the Fire Safety Standards.
    - Evacuation Elevators: Based on safety inspection standards for elevators (basic requirements for evacuation elevators).
  • LH (Korea Land & Housing Corporation) sites have adopted the Elevator Shaft Pressurization System as a design standard since July 2016.
