    (54) A method of and an air distribution means for introducing supply air into a room space


    (57) A method of introducing supply air into a lower portion of a room space (3) directly to an occupied zone (7) by means of at least one elongated air dis­tribution means (1) provided with a plurality of out­flow openings (2) for supply air. In order to blow supply air into the occupied zone without draught and without drawing impurities from the upper portion of the room space, supply air is blown from the air dis­tribution means at a high speed but through outflow openings so small that the speed of the air jets (A) from the openings is reduced essentially over a short distance (X) and the entrance of secondary air (B) from the room space into the air jets is prevented in the vertical direction of the room space over said distance (X) and at least at one end of the air dis­tribution means. The air distribution means (1) is provided with a plurality of small outflow openings (2) the distance of which from each other in the long­itudinal direction of the air distribution means is great as compared with the size of the outflow opening for enabling secondary air to flow from the room space in between the outflow openings, and to mix with the air jets from all sides.
