Patent ID: 8376819

Claim:
A ventilation, heating and/or air conditioning device comprising: a mixing chamber ( 30 ) fed by a cool air flow ( 32 ) and a hot air flow ( 31 ), the mixing chamber being provided with at least one distribution opening ( 10 , 11 ); a temperature control system ( 34 ) disposed in the mixing chamber ( 30 ) wherein the temperature control system comprises a plurality of air ducts ( 20 , 50 ) passing through the mixing chamber ( 30 ) wherein the air ducts ( 20 , 50 ) are at least partly cold air ducts ( 20 ); a pair of walls ( 22 ) spaced from each other and extending from one of the cold air ducts ( 20 ) into the mixing chamber ( 30 ) to define a cold air channel ( 341 ) extending geometrically parallel with the one cold air duct ( 20 ) with the cold air channel ( 341 ) open to the mixing chamber ( 30 ); a partition ( 24 ) intersecting the pair of walls ( 22 ) and fixed to and stationary with the pair of walls ( 22 ) and disposed between and separating the one cold air duct ( 20 ) and the cold air channel ( 341 ); the one cold air duct ( 20 ) being hollow and defined by the pair of walls ( 22 ) and the partition ( 24 ); the cold air channel ( 34 ) being defined by the pair of walls ( 22 ) and the partition ( 24 ) with the cold air channel ( 341 ) open to the mixing chamber ( 30 ) on an opposite side of the partition ( 24 ) from the one cold air duct ( 20 ); and wherein the cold air ducts ( 20 ) are directly facing the cold air flow ( 32 ) entering the mixing chamber ( 30 ) and pass through the mixing chamber ( 30 ) into the distribution opening ( 10 ).
