lindab | we simplify construction Active chilled beam Plafond Function Plafond's function is based on the induction principle. Ventilation air with a certain dynamic pressure is released through specially-formed nozzles into a dispersal zone, thereby creating a low static pressure. This low pressure causes warm air from the room to be sucked towards the ventilation air passing through the battery. The volume of the warm indoor air is 4 to 5 times that of the ventila- tion air. The air is cooled as it passes through the battery, which consists of aluminium ribs with copper ducts filled with cold running water. The heat of the room is absorbed through the aluminium ribs and then transferred through the copper pipe to the water circuit and on to a central cooling unit. Despite the small external dimensions of the product, the construction makes it possible to achieve a high cooling capacity. The nozzles releasing the ventila- tion air are designed to maintain the Coanda effect, i.e. the adhesive capacity of the air in the duct, in the nozzles. The air then follows the side of the duct towards the ceil- ing or the wall. In this way, the air "adheres" to the room's ceiling or wall, where the air velocity later diminishes. Lindab Pascal Water Solution VAV/DCV combined with active chilled beams For an extra energy- and cost saving and environmentally friendly ventilation and cooling system, the Lindab Pascal Water solution should be applied. The Pascal solution will optimize the ventilation, cooling, heating and even light- ing for a perfect indoor climate at the lowest running cost by combining the active chilled beam with VAV (Variable Air Volume) or DCV (Demand Controlled Ventilation) tech- nique. Please refer to: Pascal Water Solution documentation. Design Plafond is available in three designs: B, C and D (see pic- ture 2). The shape of the product is suitable for installation in a corner between a wall and a ceiling, or directly on a wall. If a uniform appearance throughout the whole room is desired, Plafond can be supplied either with an inac- tive part or fitted with side covers. The side covers have the same shape as the product, and can be designed to extend from wall to wall, max. 3.6 m. For the best possible accessibility for cleaning, suspen- sion, adjustment or maintenance, the whole front plate of Plafond can be removed. Valves and controls can be placed behind the front plate, so they are easily acces- sible for adjustment and maintenance. The beam is sus- pended before the front plate is put into place. Plafond can be ordered with a preset airflow at a selected air pressure. By removing the nozzle plugs or plugging more nozzles, respectively, the airflow, if necessary, can be increased or decreased at a later time. The increase, however, is limited by the number of nozzles. The water pipes are made of copper. Nevertheless, the water should be oxygen-free to prevent corrosion. Perforation pattern The beam is available in two perforation pattern Slot 50% (standard) and Dotx2 50% (plus feature). Slot 50% Dotx2 50% Picture 2: Available perforations Plafond C Picture 3.
