Abstract
A vehicle air conditioning device includes an air conditioning case having a plurality of air discharge ports, a cooling heat exchanger and a heating heat exchanger sequentially formed in an air flow path of the air conditioning case, wherein the air discharge ports each have a face vent composed of the center vent and the side vents, a left-right temperature difference reduction means for reducing the temperature difference between a discharge port of the center vent and discharge ports of the side vents by reducing, in a first air conditioning mode, the cross-sectional area of the flow path through which air is discharged to the center vent, and by reducing, in a second air conditioning mode, the cross-sectional area of the flow path through which air is discharged to the side vents.
