A heating and cooling system for an electric vehicle can rapidly perform battery cooling control in response to a battery cooling request during heating and cooling operations by including a sub-refrigerant circulation line branching from an outlet end of an indoor condenser and a sub-expansion device provided on the sub-refrigerant circulation line, thereby quickly responding to battery cooling early, continuously maintaining the cooling capacity of an evaporator without deterioration due to the initial battery cooling, reducing an operation time and the number of revolutions of an electric compressor as a whole, stopping sub-expansion through a two-way valve when the battery cooling is made to some extent and thus, maintaining the cooling capacity to the maximum.

    본 발명은 실내컨덴서의 유출단에서 분기되는 서브냉매순환라인과, 상기 서브냉매순환라인 상에 구비되는 서브팽창장치에 의해 난방 및 냉방 운전 중 배터리 냉각 요구에 대응하여 신속히 배터리를 냉각 제어할 수 있어, 배터리 냉각을 초기에 신속하게 대응할 수 있고, 초기 배터리 냉각으로 인하여 증발기의 냉방능력이 떨어지지 않고 지속적으로 유지할 수 있으며, 전체적으로 전동압축기의 운전 시간 및 회전수를 줄일 수 있고, 배터리 냉각이 어느 정도 이루어지면, 2웨이밸브를 통하여 서브 팽창을 중지시킬 수 있어, 냉방 능력을 최대로 유지시킬 수 있는 전기자동차용 냉난방 시스템을 제공한다.
