The present invention relates to a refrigerant switching valve which can control the flow of refrigerant to variously adjust cooling and heating modes in various steps. The refrigerant switching valve comprises: a valve body having an input port introducing refrigerant and a first discharge port and a second discharge port discharging refrigerant; a ball member rotatably installed in the valve body, and switching the direction of refrigerant introduced into the valve body; and an actuator rotating the ball member. The ball member is provided with a first passage connected to the input port, a second passage selectively connecting the first passage to one between the first discharge port and the second discharge port, a third passage simultaneously connecting the first passage to the first discharge port and the second discharge port, and a first expansion groove adjusting the opening degree of the second passage.

    본 발명은 냉방 및 난방 모드를 여러 단계로 다양하게 조절할 수 있도록 냉매의 흐름을 제어할 수 있는 냉매 전환 밸브에 관한 것으로, 냉매가 유입되는 입력포트 및 냉매가 배출되는 제1배출포트와 제2배출포트가 형성된 밸브 바디와, 상기 밸브 바디의 내부에 회전 가능하게 설치되고 상기 밸브 바디에 유입된 냉매의 방향을 전환시키는 볼 부재와, 상기 볼 부재를 회전시키는 액추에이터를 포함한다. 여기서, 상기 볼 부재에는, 상기 입력포트와 연결된 제1통로와, 상기 제1통로를 상기 제1배출포트와 상기 제2배출포트 중 어느 하나에 선택적으로 연결하는 제2통로와, 상기 제1통로를 상기 제1배출포트와 상기 제2배출포트에 동시에 연결하는 제3통로와, 상기 제2통로의 개방량을 조절하는 제1팽창홈이 형성된다.
