Having a constant air flow throughout a
building refreshes the air inside and is a
bases for a healthy indoor environment. It
reduces the build-up of carbon dioxide,
humidity and other hazardous substances
that circulate. Refreshing the air can be
done in a natural way (open windows
and doors), in a mechanical way or a
combination of both. The 1st option is more
ad random, while the 2nd and 3rd option
allow for a regulated and constant air flow.
How a constant air flow is being created?
Clean natural air enters into 'dry' locations
of the building through ventilation grids in
windows or walls or through a ventilation
valve.
Air circulates throughout the building via
stairs and hallways, through openings
underneath the door.
Contaminated and humid air leaves the
building through a ventilation valve in
'damp' locations of the building.
