Conventional vehicle air conditioning systems consist of a center vent and a side vent, so the air volume to the center vent and the air volume to the side vents cannot be individually controlled.

Meanwhile, a conventional vehicle air conditioning system forms holes on both sides of the vent door 21 in order to always discharge air through the side vent. Because of this, there is a problem in which some air conditioning wind is unintentionally released through the side vents in 100% floor mode, which discharges air only through the floor vents. Additionally, in the defrost mode, wind is discharged toward the side vent, which reduces the air volume toward the defrost vent (15), thereby weakening defrost performance.

Referring further to FIG. 14, in the second mix mode, the defrost vent 115 is opened by the defrost door 120 and the floor vent 117 is opened by the floor door 122. In addition, the side vent 116 is completely closed by the side vent door 121, and the center vent 126 is completely closed by the center vent door 128.

In this way, a plurality of modes are implemented so that the side vent 116 can be partially opened or completely blocked during the mix mode. In this way, by completely closing the side vent 116 in the mixed mode, the problem of unintentionally discharging hot air through the side vent 116, causing dissatisfaction to the occupants, can be solved. Therefore, it is possible to improve air conditioning satisfaction by allowing the passenger to completely close the side vent 116 when desired.

As such, the present invention variably controls the opening amount of the side vent 116 depending on the air conditioning mode, and for this purpose, a separate side vent door 121 is provided. In this case, it is also possible to use an existing door without providing a separate side vent door. When the side vent 116 and the center vent 126 are formed side by side in the front and rear directions of the vehicle, the opening amount of the side vent 116 is individually controlled, so that the side vent 116 is partially opened in floor mode and defrost mode. Alternatively, it is possible to implement a completely closed mode (100% floor mode, maximum defrost mode).

Ultimately, the air volume of the center vent 126 and the side vent 116 can be variably controlled as needed when selecting a driver or controlling air conditioning. Additionally, when rapid indoor air circulation is required, the air volume of the center vent 126 can be increased. In addition, it is possible to increase only the air volume of the side vent 116 when the wind from the center vent 126 is not desired to be directly transmitted to the occupants.

Meanwhile, the side vent 116 can be completely closed to implement 100% floor mode and maximum defrost mode. By completely closing the side vents 116 in 100% floor mode, air conditioning odors can be prevented from being discharged in front of the occupants. In addition, by completely closing the side vent 116 in the maximum defrost mode, the air volume toward the defrost vent 115 can be increased to improve defrost and dehumidification performance.

So far, the vehicle air conditioning system according to the present invention has been described with reference to the embodiments shown in the drawings, but these are merely examples, and anyone skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
