The present invention provides an air conditioning system for an electric vehicle, which can use the waste heat of a waste heat chiller and the waste heat of refrigerant stored in an outdoor condenser and a battery, thereby increasing heating performance; can cool the battery in a cooling mode, thereby enabling thermal management for the battery; can cool and heat the battery by using an electric radiator, a battery chiller, and a heating means to maintain an optimum temperature for the battery, thereby increasing the efficiency of the battery; has a dual-pipe type refrigerant distribution pipe provided at a branch point where a second refrigerant circulation line branches out of a first refrigerant circulation line such that the flow of the refrigerant can be stably and efficiently distributed on the first refrigerant circulation line, thereby increasing dehumidification performance; and allows the refrigerant to branch on a pipe, through which the refrigerant flows, without fluid resistance at the branch point and flow to the outdoor condenser, thereby enabling stable supply of the refrigerant to an evaporator.

    본 발명은 폐열 칠러의 폐열과 실외 컨덴서에 적체된 냉매 및 배터리의 폐열을 이용할 수 있어 난방성능을 향상시킬 수 있고, 냉방모드 시에는 배터리를 냉각하여 배터리의 열관리가 가능하고, 전장 라디에이터와 배터리 칠러 및 가열수단을 이용하여 배터리의 냉각뿐만 아니라 가열까지 수행할 수 있어 배터리의 온도를 최적으로 유지하여 배터리의 효율을 향상시킬 수 있으며, 이중관 형식의 냉매분배관을 제1 냉매순환라인 중 제2 냉매순환라인이 분기되는 분기지점에 구비하여, 제1 냉매순환라인 상에서 안정적이고, 효율적인 냉매의 유량 분배가 가능하여 제습 성능을 향상시킬 수 있고, 분기점의 유체저항 없이 냉매가 유동하는 배관 상에서 분기되어 실외컨덴서 측으로 냉매가 유입되므로, 증발기로 안정적인 냉매 공급이 가능한 전기자동차용 냉난방 시스템을 제공한다.
