An apparatus (10) for an HVAC system that provides air at a controllable temperature into a passenger compartment of a vehicle comprises a housing (20) defining a chamber (70). The chamber (70) has a first inlet (50) through which cold air enters the chamber and a second inlet (76) through which warm air enters the chamber. The housing (20) further includes at least one outlet (56, 58, 130, 132) in fluid communication with the chamber (70) and for directing air into the passenger compartment in the vehicle. At least one airflow diverter (90, 100) is disposed in the chamber (70) for causing a portion of the cold air flowing through the first inlet (50) to mix in the chamber with the warm air flowing through the second inlet (76).

1. An apparatus for a heating, ventilation, and air conditioning system that provides air at a controllable temperature into a passenger compartment of a vehicle, said apparatus comprising:a housing defining a chamber, said chamber having a first inlet through which cold air enters said chamber and a second inlet through which warm air enters said-chamber; said housing further including at least one outlet in fluid communication with said chamber and for directing air into the passenger compartment in the vehicle; and at least one airflow diverter disposed in said chamber, said at least one air flow diverter having at least one wall that redirects a portion of the cold air entering said chamber through said first inlet to cause a portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet. 2. The apparatus of claim 1 wherein said means for mixing extends from said housing in said chamber.3. The apparatus of claim 1 wherein said means for mixing is formed together with said housing as a continuous, unitary part.4. The apparatus of claim 1 wherein said at least one airflow diverter comprises a pair of airflow diverters disposed on opposite lateral sides of said chamber.5. The apparatus of claim 1 wherein said at least one wall has an arcuate shape.6. The apparatus of claim 1 wherein said at least one airflow diverter has a plurality of walls that redirect the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet.7. The apparatus of claim 6 wherein at least two of said plurality of walls in said at least one airflow diverter extend at right angles to each other.8. An apparatus for a heating, ventilation, and air conditioning system that provides air at a controllable temperature into a passenger compartment of a vehicle, said apparatus comprising:a housing defining a chamber, said chamber having a first inlet through which cold air enters said chamber and a second inlet through which warm air enters said chamber; said housing further including at least one outlet in fluid communication with said chamber and for directing air into the passenger compartment in the vehicle; and a pair of airflow diverters disposed on opposite lateral sides of said chamber for causing a portion of the cold air flowing through said first inlet to mix in said chamber with the warm air flowing through said second inlet. 9. The apparatus of claim 8 wherein said at least one airflow diverter extends from said housing in said chamber.10. The apparatus of claim 9 wherein said at least one airflow diverter is formed together with said housing as a continuous, unitary part.11. The apparatus of claim 8 wherein said at least one airflow diverter has at least one wall that redirects the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet.12. The apparatus of claim 8 wherein said at least one airflow diverter has a plurality of walls that redirect the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet.13. The apparatus of claim 12 wherein at least one of said plurality of walls has an arcuate shape.14. An apparatus for a heating, ventilation, and air conditioning system that provides air at a controllable temperature into a passenger compartment of a vehicle, said apparatus comprising:a housing defining a chamber, said chamber having a first inlet through which cold air enters said chamber and a second inlet through which warm air enters said chamber; said housing further including at least one outlet in fluid communication with said chamber and for directing air into the passenger compartment in the vehicle; and at least one airflow diverter for redirecting the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of cold air to mix in said chamber with the warm air entering said chamber through said second inlet, said at least one airflow diverter extending from said housing in said chamber. 15. The apparatus of claim 14 wherein said at least one airflow diverter is formed together with said housing as a continuous, unitary part.16. The apparatus of claim 14 wherein said at least one airflow diverter comprises a pair of airflow diverters disposed on opposite lateral sides of said chamber.17. The apparatus of claim 14 wherein said at least one airflow diverter has at least one wall that redirects the flow of the portion of the cold air entering said chamber through said first inlet.18. The apparatus of claim 17 wherein said at least one wall has an arcuate shape.19. The apparatus of claim 14 wherein said at least one airflow diverter has a plurality of walls that redirect the flow of the portion of the cold air entering said chamber through said first inlet.20. A heating, ventilation, and air conditioning (HVAC) apparatus for delivering air at a controlled temperature into the passenger compartment of a vehicle, said HVAC apparatus comprising:a housing having a chamber, said housing defining first and second inlets for directing airflow into said chamber and at least one outlet for directing airflow from said chamber into the passenger compartment; an evaporator core for producing a flow of cold air through said first inlet; a heater core for producing a flow of warm air through said second inlet; and at least one airflow diverter disposed in said chamber, said at least one airflow diverter for causing a portion of the flow of cold air through said first inlet to mix in said chamber with the warm air flowing through said second inlet, said portion of the flow of cold air being less than all of the flow of cold air through said first inlet. 21. The apparatus of claim 20 wherein said at least one airflow diverter extends from said housing in said chamber.22. The apparatus of claim 20 wherein said at least one airflow diverter is formed together with said housing as a continuous, unitary part.23. The apparatus of claim 20 wherein said at least one airflow diverter comprises a pair of airflow diverters disposed on opposite lateral sides of said chamber.24. The apparatus of claim 20 wherein said at least one airflow diverter has at least one wall that redirects the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet.25. The apparatus of claim 24 wherein said at least one wall has an arcuate shape.26. The apparatus of claim 20 wherein said at least one airflow diverter has a plurality of walls that redirect the flow of a portion of the cold air entering said chamber through said first inlet to cause the portion of the cold air to mix in said chamber with the warm air entering said chamber through said second inlet.27.
