Induction units for suspended ceilings Functional description Active chilled beams provide centrally conditioned ​ primary air (fresh air) to the room and use heat ​ exchangers for additional cooling and/or heating. The primary air is discharged through nozzles ​ (five variants are available) into the mixing ​ chambers; as a result of this, secondary air (room ​ air) is induced via the induced air grille and ​ passes through the horizontal heat exchanger, ​ where it is heated or cooled. Primary and secondary air mix and are then ​ supplied to the room horizontally through the ​ supply air slots....

Induction units for suspended ceilings Set of air control blades If a high cooling capacity is required in a very ​ small space with active chilled beams, optional air ​ control blades allow for adjusting the air discharge ​ pattern such that the acceptable air velocity in the ​ occupied zone is not exceeded. The airflow of ​ each active chilled beam is spread and ​ discharged according to the room geometry. If the ​ use of a room changes, the air discharge pattern ​ can be optimised by adjusting the air control ​ blades accordingly. – It is possible to adjust several air control blades ​ (i.e....
