Ducted AHU Installations Fresh Air & Extract
Ducted AHU installations are mainly used in larger building applications and generally provide tempered fresh air to various rooms. The incoming fresh air is filtered then heated or cooled as necessary prior to being supplied to the space. The AHU’s are usually located in a plant room. One of the benefits of this type of system is that all the maintenance required is carried out from within the plant room and not within the space being conditioned. The extract air is removed from the space using a separate fan system; this system can remove air from a ceiling void or be connected to grilles in the ceiling via ductwork. As the air is not recirculated.
