SMOKE CONTROL BY PRESSURISATION
 
Basic Principles

Fire induces forces create pressure differences across doors etc,which allow smoke flow through any gaps present.By altering these pressure diffferences we can control the movement of smoke.

a-)Airflow can control smoke movement if average velocity is of sufficent magnitude .(Large gaps,open doors etc.)

b-)A pressure difference across a barrier can act to control smoke movement. (Closed door etc.
 
Supply Air Parameters
 
Two parameters is important=(Air velocity through open doors)*(number of open doors)
 
Air velocity through open doors between 0,75 m/sec and 2,0 m/sec
Number of open doors is generally 2 doors
