Air mixing device having series of parallel airflow passages

An air mixer for an air distribution system for a building or similar structure, said air mixer comprising:

• a first set of air ducts forming airflow passageways for a first airflow, said first set forming two or more spaced-apart levels of air ducts that extend from a first intake side of the air mixer to an outlet side thereof;
• a second set of air ducts forming airflow passageways for a second airflow, said second set forming two or more spaced apart levels of air ducts that alternate with the levels of the first set, said second set of air ducts extending from a second intake side of the air mixer to said outlet side and extending at a substantial angle of up to about 90 degrees to the air ducts of the first set;
• and
• fixed airflow mixing devices for mixing the first and second airflows rigidly mounted at outlet ends of at least a substantial portion of the air ducts of the first set or the second set, said mixing devices comprising a series of curved vanes arranged at each level of the first set or the second set, said curved vanes acting to redirect the airflow exiting from said outlet ends of said at least a substantial portion of the air ducts,
• wherein said air mixer has a triangular shape in plan view, said triangular shape having one long side corresponding to said outlet side and two shorter sides corresponding to said first intake side and said second intake side, and wherein said mixing devices are distributed over said long side.

• a second set of air ducts forming airflow passageways for a second airflow, said second set forming two or more spaced apart levels of air ducts that alternate with the levels of the first set, said second set of air ducts extending from a second intake side of the air mixer to said outlet side and extending at a substantial angle of up to about 90 degrees to the air ducts of the first set;
• and
• fixed airflow mixing devices for mixing the first and second airflows rigidly mounted at outlet ends of at least a substantial portion of the air ducts of the first set or the second set, said mixing devices comprising a series of curved vanes arranged at a level of the first set or the second set, said curved vanes acting to redirect the airflow from said outlet ends of said at least a substantial portion of the air ducts, wherein a portion of each series of curved vanes curve upwardly so as to redirect the airflow exiting from the adjacent outlet ends upwardly and a remaining portion of each series of curved vanes curve downwardly so as to redirect the airflow exiting from the adjacent outlet ends downwardly.

An air mixer for an air distribution system for a building or similar structure, said air mixer comprising:

• a first set of air ducts forming airflow passageways for a first airflow, said first set forming two or more spaced-apart levels of air ducts that extend from a first intake side of the air mixer to an outlet side thereof;
• a second set of air ducts forming airflow passageways for a second airflow, said second set forming two or more spaced apart levels of air ducts that alternate with the levels of the first set, said second set of air ducts extending from a second intake side of the air mixer to said outlet side and extending at a substantial angle of up to about 90 degrees to the air ducts of the first set;
• and
• fixed airflow mixing devices for mixing the first and second airflows rigidly mounted at outlet ends of at least a substantial portion of the air ducts of the first set or the second set,
• wherein both sets of air ducts form horizontal airflow passageways separated by sheet metal panels that form top and bottom sides of said air ducts.

An air mixer for an air distribution system for a building or similar structure, said air mixer comprising:

• two adjacent sets of air ducts forming airflow passageways for first and second airflows, one of said sets being oriented at a substantial angle, that is less than 180 degrees, to the other of said sets, each air duct having an inlet end and an outlet end, the inlet ends of one set of air ducts being located on a first side of said air mixer, which has a triangular shape when viewed from above, and the inlet ends of the other set being located on a second side of the air mixer, the outlet ends of both sets being located on a third side of the air mixer;
• and
• air deflecting vanes for the mixing of said first and second airflows mounted at at least a portion of said outlet ends on said third side,
• wherein said deflecting vanes in use act to redirect at least a portion of one of said first and second airflows towards the other of said first and second airflows at said third side of the air mixer.
