1. An air controlling system of an air conditioner for a vehicle interior, the vehicle interior having a plurality of demand parts, comprising:
an air-conditioning case having demand parts including a face vent, a defrost vent, a foot vent, a rear console vent for discharging conditioned air with a temperature controlled to each demand part, a first interacting passage introducing a portion of the conditioned air passing through the face vent into the rear console vent, and a second interacting passage introducing a portion of the conditioned air passing through the foot vent into the rear console vent; a vent door that opens the face vent and the first interacting passage and makes the air conditioned air flow through the face vent and the first interacting passage and that closes the face vent and the first interacting passage and prevents the conditioned air from flowing into the face vent and the first interacting passage; a foot door that opens and closes the foot vent; a rear console door connected to and rotating together with the foot door; and a door switching control unit that controls switching of the doors in accordance with selected modes, wherein the door switching control unit is configured to control, in response to a foot mode, the rear console door to open the second interacting passage while closing the first interacting passage when the door switching control unit controls the foot door to open the foot vent to make the conditioned air passing through the foot vent flow into the rear console vent through the second interacting passage, thereby improving cooling and heating efficiency by enabling conditioned air to flow through the rear console vent when the air controlling system is in the foot mode in which the face vent is closed which would otherwise also close the rear console vent. |
