lindab | we simplify construction Active chilled beam Plafond Hygiene Everything is accessible The requirement for all parts of the beam to be easy to clean is met by the removable front plate (see picture 3). A cleaning hatch on the beam's air duct provides easy access so the air duct can be cleaned from the inside. The cooling battery is accessible from three sides and therefore can be cleaned thoroughly. The same applies to the Coanda nozzles, which are accessible from the sides or from underneath. All of this allows thorough cleaning of the product. It is of primary importance to be able to clean the batteries in products installed in premises with high concentrations of dust particles. Room environment The ventilation principle in Plafond can be selected according to the layout of the room and the location of the product. If the air is directed upwards, the ventilation principle is to spread the cooled air across the ceiling (see pictures 5 to 6). The heated air is then absorbed from the central area of the room and fed to the beam for fur- ther cooling. If the air is directed downwards, the ventila- tion principle is to spread the cooled air down along the walls (see picture 5). The air reaches the floor, and then it is dispersed in the room. When the room air is heated, it rises to the ceiling to be cooled again. In both scenarios, the room is well ventilated. Conventional active chilled beams, which spread the air linearly, can create high air velocities, as the air stream tends to be compressed and concentrated towards the centre. To reduce air velocities, the air distribution in the Lindab Plafond is angled outwards. The outer noz- zles point slightly outwards, which leads to air velocities that are significantly lower than those from conventional active chilled beams, with a linear outlet. As regards to noise, the nozzles are shaped like an invert- ed trumpet, i.e. some what negatively directed at the out- let, which also leads to very low noise from the nozzle. Plafond's one-way air injection is especially suited for premises where the ceiling has beams or is at different lev- els. The construction is designed to enable the product to be installed with the air direction horizontal or vertical. The product's air circulation can thereby be adapted to the con- ditions of the specific room, resulting in low air velocities. Picture 4.
