Abstract: An air control door with stratification feature is provided. The door includes a mixing section comprised of air guides that define spaced apart air passages. In a mixed mode application, where mixing of both hot and cold air streams is desired, the air control door directs the two air streams into each other, thereby promoting mixing of such air streams and reducing air stratification. By integrating a mixing section with the air control door, the present invention reduces the size, number and complexity of components required to reduce air stratification to an acceptable level.
