ABSTRACT:
An air handling system for use in an air conditioning system of an automotive vehicle includes a housing which defines an air passage. The air handling system includes a blower disposed in the housing, an evaporator disposed in the housing for cooling air which passes through it. A heater core is also disposed in the housing downstream from the evaporator for heating the air as it is passed through it. The air handling system also includes a temperature blend door system having a first temperature blend door disposed in a bypass passage defined between the evaporator and the air outlets of the housing. The first temperature blend door is pivotable about a central axis from a closed position to an open position. A shoulder is formed in the housing for sealingly engaging a first end of the first blend door when the blend door is in a fully closed position and for controlling the amount of air flowing passed the first end as the first temperature blend door is pivoted toward a fully opened position. A second temperature blend door is disposed in the passage between the heater core and the evaporator. The first and second temperature blend doors move in an coordinated motion according to a predetermined strategy.
