DID-E

Active chilled beam with one-way air discharge and horizontal heat exchanger, in nominal lengths of 900, 1200 and 1500 mm

Active chilled beam for heating and cooling, with 2-pipe or 4-pipe heat exchanger, for installation into bulkheads, e.g. in hotel rooms

  • Preferably for room heights up to 4.00 m
  • High heating and cooling capacity with a low conditioned primary air volume flow rate and low sound power level
  • High comfort levels due to low airflow velocity in the occupied zone
  • Three nozzle variants to optimise induction based on demand
  • Fixing points for various types of suspension


Optional equipment and accessories

  • Control system
  • Induced air spigot and supply air spigot (to facilitate attaching the grilles)
  • Heat exchanger powder-coated black
  • Powder coating in many different colours, e.g. RAL CLASSIC

Application

Application

  • Active chilled beams of Type DID-E for installation into ceiling bulkheads, preferably for room heights up to 4.00 m
  • Particularly suitable for hotel bedrooms and rooms on hospital wards
  • 2-pipe or 4-pipe heat exchangers enable good comfort levels with a low conditioned primary air volume flow rate
  • Energy-efficient solution since water is used for heating and cooling

Special characteristics

  • Choice of any induced air grille and supply air grille from our portfolio
  • One-way air discharge
  • Horizontal heat exchanger as 2-pipe or 4-pipe system

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)

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.
