Abstract (en)
A modular ventilation system ventilates an occupant zone having a ceiling, a floor and lateral boundaries. The ventilation system comprises a common overhead supply duct; a common overhead extract duct; a supply fan connected to the common overhead supply duct; an extract fan connected to the common overhead extract duct; and a ventilation module associated with each occupant zone. Each ventilation module includes a high-level supply vent mounted proximate the ceiling that is connected to the common overhead supply duct and an extract conduit located within the occupant zone connected to the extract duct at its upper end to the common overhead supply duct. A low-level extract vent is located at the lower end of the extract conduit having a vent aperture arranged to allow low level extraction of air from the occupant zone into the extract conduit.
