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 into ​ the mixing chambers; as a result of this, ​ secondary air (room air) is induced via the ​ induced air grille and passes through the heat ​ exchanger. Primary and secondary air mix and are then ​ supplied to the room horizontally through the ​ supply air slots. ① Front frame ② Primary air spigot ③ Casing ④ Heat exchanger...
