TVS Ventilation Systems

We address the most critical challenge underground: maintaining air quality and temperature.

Our systems ensure safe and tenable conditions during extreme heat or cold events, while keeping cross-passages and the unaffected sections of the tunnel free of smoke.

Ventilation and smoke evacuation systems

● Design of Ventilation Systems for Metro and tunnels, using designer-oriented tools for ventilation assessment models, comprehensive tunnel environment simulation software, Volumetric Simulation, and Finite Volume models.

• Comfort, emergency and anti terrorism ventilation systems designs for stations and tunnels according to NFPA 130, and SFPE Handbook.

• Evacuation plans for stations and tunnels according to NFPA 130, and SFPE Handbook.

• Hot smoke control plans using three-dimensional CFD models.

• We are specialized in the use of: SES, CADNA A, CADNA C, FDS, and BIM processes and management.

• Design of Anti-Terrorism Systems for METRO and tunnels.

• Verification of international standards for comfort and emergency.

• Sound-absorbing designs for forced ventilation rooms by three-dimensional expansion techniques using the CADNA A and CADNA C (VERIFICATION OF LAW 1540).

• Three-dimensional simulation by numerical methods to design systems of evacuation, control of gases in the environment, oxygen level, temperature, velocity, pressure in a fire situation, speed, pressure in case of a fire situation. Use of the NIST program (code developed by the U.S. Department of Transportation) to perform three- dimensional to perform three-dimensional 3D fire simulations).

• Pedestrian Flow Modelling and Simulations with LEGION.

NORMAL - CONGESTED - EMERGENCY for METRO, RAILWAY & ROAD

Our solutions are based in the fundamentals of fluid dynamics and thermodynamics and comply with legal and standards requirements.
