Staircase Pressurization Design Calculation

Flow rate of the pressurization air. Pressurization system is the most widely selected design option. As a reference according to the traditional book architects data by ernst neufert in a staircase of 125 meters two people can go up and down at once and in one of 185 meters 3 people can.

Class c and door 08 kit sobrepresion a1 s from novovent.

The airflow due to the pressurization system shall clear the stairway of this smoke.

Staircase pressurization design calculation. The data from air leakage doors will be taken from table 1. Q total maximum airflow 2505 m3h 4968 m3h 7473 m3h selected equipment. 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. Tool for contamination control not a magic shield envelope leakage is main mechanical parameter several hvac control methods differential flow control is used most often choice usually driven by envelope derive air flow accuracy spec from pressurization align engineering effort with the hazard.

Or you can use the following equation. Q 0827 a dp12. Where pg ii building is provided with a mechanical ventilation system or pressurisation system for its staircase storey shelter an automatic smoke detection system complying with ss cp 10 shall be installed. Calculation for pressure difference criterion all doors closed.

It depends on the volume of staircase and area of leakage or normally its in cfmm3. Stair case pressurization design calculation sheet 639737452 cfm 1 of 2 canadian stairwell pressurization. Staircase pressurization fan what is the equation to calculate the air flow and static pressure for fan. In this system an exterior stairwell door opens automatically upon system activation.

This course discusses the smoke control systems and examines the design considerations associated with stairwell pressurization systems. The smoke detector shall be located at the entrance of each exit staircase at every storey including the non residential floors.
