(57) A ceiling mounted device for ventilating rooms and, at the same time, cooling and/or
heating the room air includes a cooling/heating baffle (10) which has a longitudinal
primary air supply channel (11), a room air cooling/heating coil (20), a mixing chamber
(23) for cooled room/heated air and primary air, means (29) for supplying primary
air to the mixing chamber (23) through the medium of an induction effect which serves
to suck room air into the device and to pass said air through the cooling/heating
coil (20), and one or more outlet channels (22) through which a mixture of cooled/heated
room air and primary air flows essentially horizontally along the ceiling of the room.
The arrangement is characterised in that said means (29) consist of nozzles provided
in an inner wall (14) delimiting the primary air supply (11) from remaining parts
of the baffle in that part of the wall which delimits the primary air supply (11)
from the mixing chamber (23). The supply air nozzles (30,30a) which supply primary
air from the primary air channel (11) directly to the room are disposed in one or
more of the walls belonging to a casing (13) of the baffle that delimit the primary
air channel (11).
