Disclosed in the present invention is an air conditioning system for an electric vehicle, wherein a heat source for heating and cooling of the conditioned air is unified as a coolant, such that both cooling performance and heating performance may be guaranteed only with the coolant, thereby reducing the entire package. Because the temperature of the air is adjusted by means of a first air conditioning heat exchanger and a second air conditioning heat exchanger, various air conditioning modes including heating and cooling modes can be realized without an additional temperature adjustment door. Therefore, according to the present invention, the entire size of the air conditioner may be reduced. Furthermore, during heating and cooling, the first air conditioning heat exchanger and the second air conditioning heat exchanger may be integrated to be utilized, such that the size of the heat exchanger may be reduced to guarantee an indoor space. Consequently, air conditioning performance may be guaranteed without increasing the size of each heat exchanger. To this end, the present invention comprises: a heater; a cooler; and a coolant line. 본 발명에서는 공조공기의 냉난방을 위한 열원이 냉각수로 통일되고, 냉각수만으로 냉방성능 및 난방성능을 모두 확보하며, 전체 패키지가 축소된다. 즉, 제1공조 열교환기와 제2공조 열교환기를 통해 공기의 온도가 조절됨에 따라 별도의 온도조절 도어 없이, 냉난방 모드를 포함한 각종 공조모드의 구현이 가능하다. 이로 인해, 본 발명은 공조기의 전체 사이즈가 축소된다. 또한, 냉난방시, 제1공조 열교환기와 제2공조 열교환기를 통합하여 활용함으로써 열교환기의 사이즈가 축소되어 실내 공간을 확보할 수 있고, 각 열교환기의 사이즈를 키우지 않고도 공조 성능을 확보할 수 있는 전기차량용 공조 시스템이 소개된다.
