ABSTRACT:
The individual air temperature sensors normally mounted within each outlet duct in an automatic automotive heating and air conditioning system are eliminated in favor of a dual temperature sensor incorporated directly into the swinging mode door. The door swings back and forth through the central air mix area within the housing, and one end or the other of a dual sensor mounted through the door is always exposed to the air flow before it enters an outlet duct. This presents a better location for air sensing, and reduces or eliminates the time lag involved in temperature sensing when a different duct is selected, in addition to reducing part count.
