Staircase Pressurization System Design

Calculated design in a building.

Staircase pressurization system design. Pressurization system is the most widely selected design option. Characteristics the staircase pressurization system is made of a axial fan box frequency converter and air sensor pressu re. Stairwell pressurization applications. Box made from galvanised metal sheet with insulation class m1.

In the situation where all stair doors are closed the system maintains a pressure difference between the staircase and the fire floor. Stairwell pressurization fan calculation excel sheets 1062018 102300 pm if there is a fire it causes smoke to spread everywhere so we must keep the smoke away from the escape route. A pressurization system should function in two different settings to prevent smoke to enter a staircase. The smoke detector shall be located at the entrance of each exit staircase at every storey including the non residential floors.

Flow rate of the pressurization air. How it works traditionally and danfoss solution. This course discusses the smoke control systems and examines the design considerations associated with stairwell pressurization systems. At the same time excessive air flow to the staircase must be prevented so that children or less able occupants can open the access door to the staircase during an evacuation.

A system must be installed which is capable of automatically and safely supplying the two air flows. A description of stairwell pressurization system. Stair case pressurization design calculation sheet 639737452 cfm 1 of 2 canadian stairwell pressurization.
