A comfort cassette () and a method which comprises a pressure box () with an inlet () and a plurality of outlets () for through flow of a supply air flow (L). The outlets () are arranged at more than two of the pressure box edges () and form a group () of outlets per edge (). The outlets are arranged in a configuration which is changeable by outlets () of a cover member () when the cover member () is displaced in relation to the outlets () of the pressure box (). The cover member () is arranged to change simultaneously the configuration of all groups () of the outlets, by movement of the cover member () in only one direction, while the supply air flow (L) is changeable in more than two directions by movement of the cover member.

Device and method for controlling a supply air flow at a comfort cassette

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 ().
