Abstract
An air tempering apparatus for use in an automotive vehicle having a duct through which air is directed into a passenger compartment. The apparatus comprises an air chilling unit having a variable refrigerating capacity of chilling the air in the duct, and an air reheating unit having a variable reheating capacity of reheating the chilled air in the duct. A control unit decreases the reheating capacity of the air heating unit as the chilled air temperature increases. The control unit decreases the refrigerating capacity of the air chilling means when the reheating capacity of the air reheating means is greater than a predetermined value and when the sensed humidity is less than a predetermined value.
