Supply and exhaust air terminal device

摘要

A method and a supply and exhaust air terminal device arranged in a chilled beam system. The terminal comprises a supply air chamber into which supply air is led through at last one supply air opening from a supply air duct, wherein the supply air chamber is arranged in the first end of the chilled beam; and an exhaust air chamber through which exhaust air is led from a room space into an exhaust air duct through at least one exhaust air opening, wherein the exhaust air chamber is arranged in the second end of the chilled beam and separated from the supply air chamber. The air terminal device further comprises an adjusting device configured to adjust the at least one supply air opening and the at least one exhaust air opening; and an actuator for displacing the adjusting device, wherein displacing the adjusting device causes the air flow to be obstructed through the at least one supply air opening and through the at least one exhaust air opening.
