Abstract
An air mixing unit for a ventilation system includes a housing with a control door to control at least one inlet air stream, a mode door to control at least one outlet air stream and air passages for supplying air through said mixing unit. An air duct system that is arranged to be attached to said control door funnels air from one side of said mixing unit to the other.

An air mixing unit for a ventilation system, comprising a housing with a control door to control at least one inlet air stream, a mode door to control at least one outlet air stream, air passages for supplying air through said mixing unit and an air duct system to funnel air in a lateral direction from one side of said mixing unit to the other, wherein said air duct system is coupled to and downstream of said control door.
An air mixing unit for a ventilation system, comprising a housing with a control door to control at least one inlet air stream, a mode door to control at least one outlet air stream, air passages for supplying air through said mixing unit and an air duct system, attached to said control door, comprised of alternating layered first and second air ducts arranged to feed first and second layers of different temperature air into said air.
A method for mixing air in a ventilation system comprising:
- directing a first stream of air of a first temperature into a housing at a first inlet;
- directing a second stream of air of a second temperature which is different than the first temperature into the housing at a second inlet;
- and
- converging the first and second air streams within the housing at an opening governed by a rotatable control door that Includes an attached integral air duct, wherein the angle of rotation of the control door causes the air duct system to deflect a predetermined amount of the first air stream toward the second inlet and a predetermined amount of the second air stream toward the first inlet.
An air mixing unit in a ventilation system comprising a first inlet for a first stream of air, a second inlet for a second stream of air, an outlet, and a channel situated between the inlets and outlet wherein the movement of air through the channel is governed by a rotatable control door and an integral air duct attached to the control door such that the control door's angle of rotation causes a predetermined amount of air from the first inlet to pass in a lateral direction through the air duct toward the second inlet and a predetermined amount of air from the second inlet to pass in a lateral direction through the air duct toward the first inlet.
