ABSTRACT:
An automobile air conditioner of a reheat air mix type, having an evaporator disposed in a duct and a heater core disposed in the duct at the downstream side of the evaporator. Chilled air passages are formed between both sides of the heater core and the surfaces of opposing walls of the duct. The chilled air passages are extended to form a first duct leading to an upper air outlet to the room of automobile and a second duct leading to a lower air outlet opening to the room. A part of the warmed air coming from the heater core is delivered to the first duct while the other part is delivered to the second duct. The air conditioner further has a first air mix damper for controlling the ratio between the flow rate of chilled air flowing into the heater core and the flow rate of the chilled air flowing into the first duct, and a second air mix damper for controlling the ratio between the flow rate of chilled air introduced into the second duct and the flow rate of warmed air flowing from the heater core into the second duct.
