The primary supply air enters the plenum of the active chilled beam, from where it is diffused into the room through nozzles and supply slots located at the bottom of the beam. The supply air nozzle jets induce efficiently ambient room air through the heat exchanger, where it is either cooled or heated. The supply air jet is directed horizontally along the ceiling surface. Four different nozzle sizes are available to enable different supply airflow rates. The cooling and heating capacities of the chilled beam are controlled by regulating the water flow rate according to the control signal of...

Servicing CODE DESCRIPTION 1 Bottom panel 8 Chilled & hot water pipe connections Open the bottom panel of the chilled beam. Clean the supply air plenum, duct and finned coils of the heat exchanger using a vacuum cleaner, taking care not to damage the finned coils. Clean the bottom panel and, if required, the side plates using a damp cloth. Cooling The recommended cooling water mass flow rate is 0.03 - 0.10 kg/s, resulting in a temperature rise of 1 - 3°C in the heat exchanger. To avoid condensation the recommended inlet water temperature of the heat exchanger is 14 - 16°C. Heating The recommended...
