Abstract
Method and air treatment device () for control of supply air flow (L). The air treatment device () comprises a chilled beam () with a pressure box () comprising an inlet () for inflow of supply air flow (L) and a plurality of outlets () for outflow of the supply air flow (L) out of the pressure box (). The air treatment device () comprises an actuator () for control of supply air flow (L), and the pressure box () comprises at least one pressure measuring socket () for control of static pressure (ps). The air treatment device () registers the static pressure (ps) and the position of the actuator (), and calculates the real supply air flow (L). The actuator () is arranged to change the configuration of the outlets () by a linear motion of a cover member () and change the open area of the outlets ().
