How Essential is a Fresh Air Plant to the integrity of a building and what is it's primary function?
The FAHU is basically the nose of a building, to inhale fresh air and to exhale exhaust air. There are exhaust air taken out from the kitchen and toilets. Also if same air is circulated inside a control volume the oxygen level will deplete. The volume of conditioned air is actually leaving the control volume as exhaust. In order to substantiate the same volume of fresh air needs to be supplied to the buildings. Hope the function of FAHU is clear to you.
