Claims
- 1. Air delivery apparatus comprising, in combination, an air bar assembly and an induction box, said air bar assembly comprising an air delivery section including an elongate channel having a web and opposed sidewalls, there being a plurality of longitudinally spaced openings in the web of said channel, means operatively associated with said channel and effective in combination therewith to form a duct having the web of said channel as one wall, the duct being essentially closed except for the openings in the web of said channel, a divider interior of and effective to divide the duct into a primary duct spaced from the web of said channel and a secondary duct adjacent the web of said channel, there being a plurality of openings in said divider through which air can flow between the primary and secondary duct, and valve means for controlling the flow of air through the openings in said divider, said induction box having means forming a passage for air flow from an inlet end to an outlet end, and at least one induction nozzle through which air flowing through the passage passes, there being an opening from the exterior of said induction box to the interior thereof, which opening is so positioned that air flowing through said induction nozzle induces a flow of air into said induction box, a duct for delivering air from the primary duct of said air bar assembly to the inlet end of said induction box, and a duct for delivering air from the outlet end of said induction box to the secondary duct of said air bar.
- 2. Air delivery apparatus comprising, in combination, an air bar assembly and an induction box, said air bar assembly comprising an air delivery section including an elongate channel having a web and opposed sidewalls, there being a plurality of longitudinally spaced openings in the web of said channel, means operatively associated with said channel and effective in combination therewith to form a duct having the web of said channel as one wall, the duct being essentially closed except for the openings in the web of said channel, and a divider interior of and effective to divide the duct into a primary duct spaced from the web of said channel and a secondary duct adjacent the web of said channel, said induction box having means forming a passage for air flow from an inlet end to an outlet end, and at least one induction nozzle through which air flowing through the passage passes, there being an opening from the exterior of said induction box to the interior thereof, which opening is so positioned that air flowing through said induction nozzle induces a flow of air into said induction box, a duct for delivering air from the primary duct of said air bar assembly to the inlet end of said induction box, and a duct for delivering air from the outlet end of said induction box to the secondary duct of said air bar.
- 3. Air delivery apparatus comprising, in combination, an air bar assembly, an induction box and a primary duct for deliverying conditioned air to the apparatus, said air bar assembly comprising an air delivery section including an elongate channel having a web and opposed sidewalls, there being a plurality of longitudinally spaced openings in the web of said channel, means operatively associated with said channel and effective in combination therewith to form a duct having the web of said channel as one wall, the duct being essentially closed except for the openings in the web of said channel, said induction box having means forming a passage for air flow from an inlet end to an outlet end, and at least one inductor, there being an opening from the exterior of said induction box to the interior thereof, which opening is so positioned that the inductor induces a flow of air into said induction box for mixture therein with conditioned air, a duct for delivering conditioned air from said primary duct to the inlet end of said induction box, and a duct for delivering a mixture of conditioned air and induced air from the outlet end of said induction box to the duct of said air bar.
