THREE-DIMENSIONAL MESH VENTILATION SYSTEM Three-Dimensional Mesh Ventilation System™.
Three-dimensional mesh ventilation system that achieves both improved working environment and energy conservation
In shield tunnel construction, segment seal application work generates organic solvents, requiring adequate ventilation to maintain the working environment.
The three-dimensional mesh ventilation system was developed to solve this challenge. It controls airflow in three dimensions according to the work content and work area, efficiently ventilating the necessary locations.
Furthermore, the technology cultivated through development—delivering the necessary amount of air only to the places where it is needed—is applied not only to countermeasures against organic solvents, but also to energy conservation, temperature and humidity control, and the improvement of the overall working environment. From “ventilation” to the ”optimization of the air environment.”
The three-dimensional mesh ventilation system achieves an efficient air environment in tunnel construction.
Product Overview
forte
- Targeted ventilation suited to the work
Optimize the ventilation areas according to the type of work and location. Efficiently ventilate the necessary areas to maintain a comfortable working environment. - Achieving high-efficiency ventilation with original airflow control
The proprietary design, which captures airflow efficiently before it spreads, achieves high ventilation performance while preventing equipment from becoming larger. - High-precision airflow management using four devices
Integrated design from supply to exhaust. It suppresses air stagnation and forms the planned ventilation airflow. - Contribute to energy conservation
It contributes to the reduction of power consumption and operating costs by ventilating only the necessary areas. - Optimal design for each site
We will propose the optimal ventilation rate and equipment layout according to the size of the soundproof house and the work details.
Comparison of conventional ventilation and 3D mesh ventilation systems
Conventional ventilation methods required a large airflow and a lot of power to uniformly ventilate the entire soundproof house.
The three-dimensional mesh ventilation system achieves a reduction in power consumption while maintaining ventilation performance by supplying the required airflow to the necessary locations.
Electricity consumption comparison
Achieved a reduction in electricity consumption of approximately 561 TP3T compared to previous levels
