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 chamber; as a result of this, secondary air (room air) is induced via the induced air grille and passes through the horizontal heat exchanger.

Primary and secondary air mix and are then supplied to the room horizontally through the supply air grille.

Installation and commissioning

  • Preferably for rooms with a clear height up to 4.00 m
  • Installation into ceiling bulkheads
  • Side entry primary air spigot
  • Lengths of 948, 1248, and 1548 mm, and width of 576 mm (heat exchanger 256 mm) or 640 mm (heat exchanger 320 mm)
  • Installation and connections to be performed by others; fixing, connection and sealing material to be provided by others
  • Active chilled beam has 4 suspension points (Ø6.4 mm) for on-site installation (by others)
  • Heat exchangers are fitted with water flow and water return connections at the narrow side
  • Induced and supply air spigots (accessories) facilitate mounting the grilles (an installation subframe for the concealed screw fixing is not required)
  • If the cover for the induced air opening is provided by others, e.g. with a perforated plate, that plate must have a free area of at least 65 %.

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.
