TOMECO – SODECA JETFAN

In recent years, horizontal ventilation systems, also known as non-pipeline ventilation and ventilation systems, have been developed and developed to replace traditional systems based primarily on network of pipelines and air intake in Vietnam in particular and in the world in general.

The above ventilation solution is built on a part of the principle of ventilation systems that have been widely used in the field of construction of traffic tunnels, in which propeller fans are used to create a flow of air. with the right speed to sweep through the entire area to be ventilated.

Fans installed at the inlet and outlet positions create a movement of air flow, thereby pushing air and smoke out of the area to be ventilated in the shortest time.

The jet fans ventilation system works based on impulse for a small amount of air moving at high speed to indirectly affect the surrounding air masses.

This system also allows maintenance of exhaust gas concentrations throughout the parking lot at a reasonable level without operating the entire ventilation system of the parking lot.

By operating push fans in conjunction with central control systems and exhaust gas sensor sensors, users can save operating costs, reduce noise levels and extend equipment life.

With push ventilation system, users can completely build a fire protection system to ensure efficiency in operation and cost

Private, not only in accordance with QCVN 06: 2010 / BXD but also meet all other standards widely applied in the other world such as the standards of the United Kingdom, the Kingdom of Belgium, Draft Control Standards smoke at the Parking lot of the European Union Standard Council EN 12101-11, which clearly defines the effectiveness in:

• Create favorable conditions for extinguishing the fire
• Facilitating the evacuation of people and property in the area of fire incidents.
• Smoke in the event of a fire & after the fire is extinguished.

With a team of consultants to design ventilation and smoke control systems – PCCC, we are ready to provide consulting services for customers’ demand for fans, including surveys and preliminary studies. set, calculation of fan selection and fan layout plan.

Aerodynamic calculation simulation is a widely applied method in the world to demonstrate the ability to operate effectively of fan jet ventilation for specific projects.

The aerodynamic simulation software used by consultants of TOMECO and SODECA can provide customers with detailed forecasts about the direction of operation, temperature, density of air and smoke inside the yard. park in normal conditions and when a fire occurs. This is done based on inputs such as the architecture and size of the parking lot, fan operating parameters … and aims to ensure that the system performs functions to remove smoke from the parking lot. and maintain the concentration of emissions at the permitted level effectively.
