In Building Services Engineering Ventilation Systems Are Used For Commercial Premises, Hospitals, Restaurants Or Conference Rooms To Ensure The Air Exchange In The Individual Rooms. In Real Air Handling Units The Air Is Heated Or Cooled By A Heat Exchanger And Cleaned By Filters, E.G. From Pollen.
It Demonstrates The Operation Of A Ventilation System And Its Components. The Components Used Are Common In Commercial Ventilation Technology And Therefore Are Of High Practical Relevance. The Ventilation System Is Operated As A Pure Air Supply System.
The Air Enters Via A Weather Louvre And Flows Through The Components Of The Ventilation System, Such As Multi-Leaf Damper And Filter. A Fan Ensures The Air Transport. Further Down The Air Duct, Typical Components, Such As Sound Insulation Link, Inspection Flap, Various Air Outlets And Fire Protection Flap Are Arranged.
