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.

An automobile air conditioner in which a warm air heated by a heater core and a cold air by-passing said heater core are mixed at a controlled ratio to provide conditioned chilled air and conditioned warm air, the conditioned chilled air being discharged to an upper part of a passenger compartment through an upper air outlet while the conditioned warm air is discharged to a lower part of the compartment through a lower air outlet, comprising: a main chilled air passage means and a sub-chilled air passage means for by-passing said heater core; an evaporator upstream of both of said main chilled air passage means and said sub-chilled air passage means; a main warm air passage means and a sub-warm air passage means for distributing warm air coming out of said heater core at a suitable ratio; a first duct means for mixing chilled air from said main chilled air passage means and the warm air from said sub-warm air passage means, said first duct means being adapted to introduce the mixture to said upper air outlet; a second duct means for mixing the chilled air from said sub-chilled air passage means and the warm air from said main warm air passage means, said second duct means being adapted to introduce the mixture to said lower air outlet; a first air mix door for controlling the ratio between the flow rate of chilled air introduced into said heater core and the flow rate of chilled air flowing into said main chilled air passage means, said first air mix door being on the inlet side of the heater core and disposed at a branching point of the main chilled air passage means and a passage for air flowing into the heater core and reciprocally controlling an opening area of the main chilled air passage means and an opening area for the heater core from zero to maximum; and a second air mix door for controlling the ratio of mixing of the chilled air flowing from said sub-chilled air passage means into said second duct means and the warm air flowing from said main warm air passage means into said second duct means, said second air mix door being on the outlet side of the heater core and disposed at a meeting point of the main warm air passage means and the sub-chilled air passage means and reciprocally controlling an opening area of the main warm air passage means and an opening area of the sub-chilled air passage means from zero to maximum.
