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 (four variants are available).
As a result of this, secondary air (room air) is induced and passes through the heat exchanger.
Primary and secondary air mix and are then supplied to the room horizontally.

Active chilled beams of Type DID-SB, with two-way air discharge and high thermal output, providing high thermal comfort levels; for visible installation about 300 mm below the ceiling slab in rooms without a suspended ceiling.
Preferably for room heights up to 4.00 m.
The units consist of a casing with suspension points, a spigot, non-combustible nozzles, and a horizontal heat exchanger.
Four nozzle variants to optimise induction based on demand.

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.
