The diagram above shows a common technique for installing supply ducts in the pool room. Dry air is directed upward over the windows A, B, C
and D. As the air picks up moisture from the pool room, it is drawn towards the return air grill E where it re-enters the pool conditioner. Air is released
over the glass and drawn to the return air grill of the PC with as little travel as possible over the pool surface.
Supply ducts "F" are located below the concrete pool decking and insulated with waterproof closed cell or styrofoam insulation so that the air at
each supply grill is at approximately the same temperature.
Floor diffusers "G" should be placed close to the windows and be wide enough to direct air over the entire glass surface to ensure that no
condensation occurs in corners or on the lower levels of the glass.
