The present invention relates to an individual air conditioning control system for front and rear seats in an electric automobile, which has an HVAC main body and an indoor distributor separated from each other, and is able to control four zones (left and right zones on a front row, and left and right zones on a rear row) by using a single blower, comprising: an HVAC main body; an evaporator built in the HVAC main body; a PTC heater; an input unit respectively receiving a preset temperature of the driver's seat and the passenger's seat next to the driver's seat; a left temperature detection unit and a right temperature detection unit detecting an air temperature passing through a left side and a right side of the PTC heater; a control unit outputting a control signal controlling the PTC heater based on the temperatures measured by the left and right temperature detection units as well as the preset temperature inputted from the input unit; and a power supply unit controlling the power supplied to the PTC heater in accordance with the control signal outputted from the control unit. Hot air or cold air is discharged to the driver's seat and the passenger's seat next to the driver's seat in accordance with the signal of the control unit. The four zones (left and right zones on a front row, and left and right zones on a rear row) can be controlled by using a single blower since the inside of the HVAC main body is divided by a barrier and an indoor distributor. The barrier is horizontally installed to be airtight between the evaporator and the heater in the HVAC main body. The indoor distributor includes a front seat valve installed on a front seat outlet, and a rear seat valve installed on a rear seat outlet for distributing the air from the main body to each outlet. Therefore, the air volume control can be conducted.

    본 발명은 HVAC 본체와 실내분배기가 분리되어 있어 있으며, 1개의 블로워를 이용하여 4존 제어(전석좌우, 후석 좌우) 제어가 가능한 전기자동차용 전후석 개별 공조 제어시스템으로, HVAC 본체; 및 상기 HVAC 본체에 내장되는 증발기, PTC 히터, 운전석과 보조석의 설정온도를 각각 입력받는 입력부, PTC 히터의 좌측 및 우측을 통과하는 공기 온도를 감지하는 좌측 및 우측 온도감지부, 상기 입력부로부터 입력된 설정온도와 상기 좌측 및 우측 온도감지부로부터 각각 측정된 측정온도를 바탕으로 PTC 히터를 제어하는 제어신호를 출력하는 제어부; 및 상기 제어부의 출력된 제어신호에 따라 PTC 히터에 공급되는 전원을 조절하는 전원공급부를 포함하며, 상기 제어부의 신호에 따라 온풍 또는 냉풍을 운전석 및 보조석으로 토출하도록 한 HVAC 공조제어 시스템에 있어서, 상기 HVAC 본체 내에 격벽과 실내분배기에 의해 분리되어 하나의 불로워를 이용하여 4존(전석(前席) 좌,우 및 후석(後席)의 좌,우) 제어가 가능하도록 하고, 상기 격벽은 HVAC 본체 내에 설치되는 증발기와 히터 중간 위치에 수평으로 기밀하게 설치되며, 상기 실내분배기는 본체에서 나오는 바람을 각 토출구로 분배하기 위해 전석토출구에 설치되는 전석밸브와 후석 토출구에 설치되는 후석밸브로 구성된다.
