Abstract: An air distribution device. The air distribution device an air distribution chamber arranged to receive a flow of ventilation air from the air outlet. The air distribution chamber further having one or more perforated throttling plates or meshes perpendicular to the inner perforated wall and perpendicular to the flow of ventilation air from the air outlet into the air distribution chamber. The air distribution device also includes a pressure equalization chamber formed between an inner air permeable front plate of the air distribution chamber and an outer front plate. A perforation-free area of the outer perforated front plate is smaller than the perforation-free area of the inner perforated front plate in order to equalize ventilation air pressure in the equalization chamber and to provide a uniform flow of air through the outer front plate.

Abstract: The invention concerns a supply air terminal device (10) and a method for regulating the airflow rate. The supply air terminal device (10) comprises a heat exchanger (11), with which a circulated airflow (L2) conducted from a room can be either cooled or heated. The supply air terminal device (10) comprises a mixing chamber (12), into which mixing chamber (12) the air chamber's (15) nozzles (16a1, 16a2 . . . 16an) or a flow gap (16) open to conduct a primary airflow (L1) into the mixing chamber (12), whereby the primary airflow (L1) from the nozzles (16a1, 16a2 . . . 16an) or through the flow gap (16) as a flow (Qs) will induce a circulated airflow (L2) from the room (H) to flow through the heat exchanger (11) into the mixing chamber (12). The combined airflow (L1+L2) is conducted into the room (H). The supply air terminal device (10) comprises a regulator (100) bypassing the nozzles (16a1, 16a2 . . .
