Abstract
An air conditioner for vehicles is disclosed. This air conditioner feeds recirculation and fresh air in a separate air feeding or a mixed air feeding using a single intake duct and a single intake control door, thus improving its heating and defrosting efficiency during a heating mode operation, and preventing an undesired discharging of white fogging from the vents during a cooling mode operation by changing its air feeding mode from a recirculation air mode to a fresh air mode. This air conditioner also has a simple construction and is reduced in its production cost.

- a single scroll case having first and second compartments, the first compartment having an opening on a first scroll case wall, the second compartment having an opening on a second scroll case wall;
- a single door located in an area in proximity to the first and second inlets, the door being configured to change a position thereof within the door area;
- a first air passage extending from the door area to the opening of the first compartment;
- a second air passage extending from the door area to the opening of the second compartment along a housing wall, which is a wall of the housing formed around the first and second scroll case walls;
- and
- a structure formed on a surface of the scroll case facing the door area;
- wherein the single door and the first and second inlets are all configured to face one or the other of the openings of the first and second compartments, the structure comprises a wall extending from the scroll case toward the door area, the structure is configured such that the position of the door relative to the structure can control air flows into the first and second passages from at least one of the first and second inlets, and the structure is further configured such that, when the door is in a position closest to the structure, he first air passage is connected substantially to the first inlet while the second air passage is connected substantially to the second inlet.
