Abstract
Ventilation system (1) of a tunnel or covered road section (2), in which the tunnel (2) comprises at least a first tunnel tube or carriageway (11; 11, 12) with a first entrance (3; 3, 5) and a first exit (4; 4, 6) for traffic (T1; T1, T2) through the at least first tunnel tube (11), and the ventilation system (1) is equipped for: —the production of a blind flow or recirculation flow of air inside the at least first tunnel tube during use, and —the controlled discharge of air from the blind flow or recirculation flow at the entrance and/or exit of the at least first tunnel tube.

Ventilation system (1) of a tunnel or covered road section (2), in which the tunnel (2) comprises at least a first tunnel tube (11;
- 11, 12) with a first entrance (3;
- 3, 5) and a first exit (4;
- 4, 6) for traffic (T1;
- T1, T2) through the at least first tunnel tube (11;
- 11, 12), in which the ventilation system (1) comprises an air barrier (L1, L2;
- L1, L2, L3, L4) at each end (3, 4;
- 3, 4, 5, 6) of the at least one tunnel tube (11;
- 11, 12), and in which each of the air barriers during use is capable of forming a barrier against polluting particles coming out of the tunnel, the ventilation system comprising air pumps (C1, C2;
- C1, C2, C3, C4) for extracting air at one barrier and supplying that air to another barrier at an other end of the at least first tunnel tube and the ventilation system (1) is equipped for:
- —the production of a blind flow or recirculation flow of air inside the at least first tunnel tube during use, and —the controlled discharge of air from the blind flow or recirculation flow at the entrance and/or exit of the at least first tunnel tube.
