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 (in 5 variants) into the mixing chambers; as a result of this, secondary air is induced.
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.

Active chilled beams of Type DID614, with four-way air discharge and high thermal output, for air-water systems.
For installation flush with the ceiling, preferably in rooms with a height up to 4.00 m.
The units consist of a casing with suspension points, a spigot, non-combustible nozzles, and a horizontal heat exchanger.
Five nozzle variants to optimise induction based on demand, including adjustable twin nozzles, i.e. one pair of nozzles with different diameters.

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.
If the air discharge is not straight, the water-side capacity will be slightly affected. Blades set at 45° may cause a loss of up to 5 %. Air control blades have to be factory fitted; it is not possible to retrofit air control blades at a later stage. Design variant D2 cannot be fitted with air control blades.
Illustration shows construction with water connections on the right. In constructions with the water connections on the left, the water connections are on the opposite side.

Mixed flow
The supply air is discharged from the diffuser into the space with a velocity between 2 and 5 m/s. The resulting air jet mixes with the room air, ventilating the entire space. Mixed flow systems typically provide a uniform temperature distribution and air quality within the space. The originally high velocity of the turbulent air jet decreases rapidly due to the high induction levels of mixed flow systems.
Heat exchanger
The maximum water-side operating pressure for all heat exchangers is 6 bar.
The maximum water flow temperature (heating circuit) for all heat exchangers is 75 °C; if flexible hoses are used, the water flow temperature should not exceed 55 °C. Units for other pressures and temperatures are available on request.
The water flow temperature (cooling circuit) should be at least 16 °C such that it does not permanently fall below the dew point. For units with a condensate drip tray the water flow temperature may be reduced to 15 °C.
Heat exchanger as 2-pipe system
Air-water systems with a 2-pipe heat exchanger may be used for either heating or cooling. In changeover mode it is possible to use all units within a water circuit exclusively for cooling in summer and exclusively for heating in winter.
Heat exchanger as 4-pipe system
Air-water systems with a 4-pipe heat exchanger may be used for both heating and cooling. Depending on the season, i.e. especially in spring and autumn, it may be possible that an office has to be heated in the morning and cooled in the afternoon.
