Apparatus for mixing air in a vehicle HVAC system
First Claim
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.

Abstract
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).

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. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. 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 flows into said chamber and a second inlet through which warm air flows into 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 in said chamber, said at least one air flow diverter reducing the velocity of a portion of the cold air flowing into said chamber through said first inlet, said portion of the cold air flowing through said first inlet being less than all of the cold air flowing through said first inlet, said portion of cold air mixing in said chamber with the warm air entering said chamber through said second inlet.
