Mechanical automation systems, depending on the electro-mechanical infrastructure, field of activity and comfort needs of the enterprises, increase the efficiency with resource optimization and minimize the human factor, thus saving a great deal of operating costs.

In classic car park ventilation systems, both fresh air and discharged air are drawn through fans and air-ducts. To prevent pressure decrease, the system must be operated at low air velocity. However, this means that the ducts must be wide and therefore take up a lot of space. We use a completely different method of jet ventilation. Here, a small amount of air is absorbed by the fan and then removed at high speed. When this air hits the air in front of the fan, it pushes it forward while also pulling in the air around it. In this way, all the air in the environment is activated and transported to a distance of 20-40 meters without using air-ducts. The entire car park is controlled by these air movements, and smoke evacuation is performed quickly and easily.

Computational Fluid Dynamics (CFD) is a method that provides a detailed calculation of air flow. The environment to be simulated is modelled in 3D. The system is stimulated in a computer environment by placing the jet fan according to the air exchange rates and ambient geometry. Using the data obtained here, the system has been improved and the best solution has been provided.

After computer simulations, the accuracy of the system can be confirmed by cold smoke testing.
