A system for supplying air under the ceiling of a room comprising a pair of air inlet openings arranged side by side and configured to supply a pair of air streams into the room along the ceiling. The pair of air inlet openings are controllable to assume a first configuration for supplying a relatively high air flow in divergent directions and with a direction component towards the ceiling, and a second configuration for supplying a relatively low air flow where the supplied pair of air streams have second air stream directions are non-divergent and do not have direction components towards the ceiling. |
