The length of the right duct 150 is relatively short and the length of the left duct 140 is relatively long because the rear air conditioning apparatus 100 is installed on the side (right side) of the vehicle. do.

At this time, since the flow path from the right vent 123a to the right duct 150 is short, the static pressure is low and the flow from the left vent 122a to the left duct 140 is long, so that the static pressure becomes high.

Therefore, the vent (the right vent 123a) having a relatively lower static pressure among the left vent 122a and the right vent 123a is formed to be smaller than the vent having a relatively higher static pressure (the left vent 122a). In other words, since the flow path from the left vent 122a to the left duct 140 is long and the static pressure is high, the size of the left vent 122a is formed larger than the right vent 123a, The amount of air supplied to the left and right sides of the air conditioner can be made uniform.

Meanwhile, the discharge case 121 is provided with an actuator 160 for operating the mode door 125.

Hereinafter, the operation of the back seat air conditioning system for a vehicle according to the present invention will be described. For convenience, the case where the air discharge mode is the face mode will be described as an example.

First, in the face mode, the mode door 125 opens the left and right vents 122a and 123a of the face vent 124a and closes the floor vent 124b.

The temperature control door 115 controls the openings of the cold air passage P1 and the hot air passage P2 according to a cooling mode, a heating mode and a mixing mode. In FIG. 10, the cold air passage P1, (P2) are all opened.

Subsequently, when the air blowing device 130 is operated, the air sucked through the air inlet 133 of the scroll case 131 is blown into the air conditioning case 110.

After the air blown into the air conditioning case 110 is cooled while passing through the evaporator 101, some of the cool air bypasses the heater core 102 by the temperature control door 115, It is converted into hot air while passing through the core 102. [

The cool air and the warm air flow toward the discharge case 121 through the air outlet 116. The cool air and the warm air are smoothly mixed in the air mixing area 125b inside the mode door 125, Some air is discharged to the left vent 122a, and some air is discharged to the right vent 123a.

The air discharged to the left vent 122a and the right vent 123a flows through the left duct 140 and the right duct 150 connected to the duct connecting portions 105 and 106, .
