VAV Systems (Variable Air Volume)

It is developed for especially multi-zone applications and variable load volumesflow is modulated which is central plant control device with the capacity of the frequency converter in the main supply fan in VAV systems. The air output at the plant's outlet is constant. Variability is compared by changing the amount of air which is given into the room by VAV boxes. Cooling load of the room is balanced by adjusting the amount of cooled air with the room's controller.
