Abstract

In the room of a building, a channel extends across above ceiling level and supports ceiling panels which form the ceiling itself, part of the channel being concealed by ceiling panels extending beneath the channel. Lighting elements are mounted in the other part of the channel, and air injection apertures extend along and outside each side of this part of the channel, for injecting air into the room.
