PS Ventilation- Smoke extraction -

E. Da Riva, S. E. Wojnarska 22013-02-01

Boundary conditions / assumptions:

Only SEVS system

Extraction in TR3-TR8, 30 000 m3/h each

Air inlets in the galleries corresponding to TR1 and T2

Two cases! With 25 000 m3/h injection in the center and without

Air inlets

Smoke extractors

E. Da Riva, S. E. Wojnarska 32013-02-01

Boundary conditions / assumptions:

Extraction: velocity ~5m/s, area 1,7m2 (velocity inlets)

Inlets: TR1: 3,0m X 3,4 m; TR2: 1,2m X 2,0m (pressure inlets)
