IDB 

Brüstungsinduktionsdurchlass für Nennlängen von 600, 900, 1200, 1350 mm mit vertikalem Wärmeübertrager und Kondensatwanne

Under sill induction unit with 2-pipe or 4-pipe heat exchanger, of compact height, for installation under a sill or on a wall. The condensate drip tray is useful if the temperature temporarily falls below the dew point.

  • 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
  • Four nozzle variants to optimise induction based on demand


Optional equipment and accessories

  • Control equipment
  • Lint screen to protect the heat exchanger from contamination
  • Powder coating in many different colours, e.g. RAL CLASSIC

Application

Application

  • Type IDB under sill induction units of compact height, for installation on an external wall, e.g. under a sill.
  • Inducing displacement flow
  • 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

  • Supply air discharge as inducing displacement flow
  • Vertical heat exchanger as 2-pipe or 4-pipe system, optional condensate drip tray including condensate drain that can be connected to a condensate pipe (to be provided by others)
  • Water connections at the narrow side, Ø12 mm Cu pipe, with plain tails or with G½" external thread, or with a G½" union nut; with flat seal

Functional description

Under sill induction units provide centrally conditioned primary air (fresh air) to the room and use heat exchangers for cooling and/or heating.

The primary air is discharged through nozzles and induces secondary air (room air), which passes through the heat exchanger.

Primary and secondary air mix and are then supplied to the room as an inducing displacement flow.

Inducing displacement flow

The supply air is discharged near the external wall and with a medium velocity between 1.0 and 1.5 m/s. Due to the induction effect the supply air velocity is rapidly reduced such that, in cooling mode, the supply air displaces the room air over the entire floor area. The convection from people and other heat sources causes the fresh air from the pool to rise and create comfortable conditions in the occupied zone.

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.
