The present invention relates to a refrigerant switching valve capable of controlling the flow of a refrigerant such that cooling and heating modes can be controlled to various stages. The refrigerant switching valve includes: a valve body having an inlet port into which a refrigerant is introduced and a pair of outlet ports from which the refrigerant is discharged; a ball member rotatably installed inside the valve body and allowing or disallowing the transfer of the refrigerant or switching the same; and an actuator rotating the ball member. The ball member comprises: a transfer passage transferring the refrigerant by connecting the inlet port to at least one of the pair of outlet ports; an expansion groove expanding the refrigerant discharged through at least one of the pair of outlet ports; and an expansion passage connecting the transfer passage to each of the pair of outlet ports and expanding the refrigerant discharged through the pair of outlet ports.

    본 발명은 냉방 및 난방 모드를 여러 단계로 다양하게 조절할 수 있도록 냉매의 흐름을 제어할 수 있는 냉매 전환 밸브에 관한 것으로, 냉매가 유입되는 입력포트와 냉매가 배출되는 한 쌍의 배출포트가 형성된 밸브 바디와, 상기 밸브 바디의 내부에 회전 가능하게 설치되며 냉매의 이송을 허용 또는 차단하거나 전환하는 볼 부재와, 상기 볼 부재를 회전시키는 액추에이터를 포함한다. 상기 볼 부재에는, 상기 입력포트를 상기 한 쌍의 배출포트 중 적어도 하나에 연결하여 냉매를 이송시키는 이송통로와, 상기 한 쌍의 배출포트 중 적어도 하나를 통해 배출되는 냉매를 팽창시키는 팽창홈과, 상기 이송통로를 상기 한 쌍의 배출포트에 각각 연결하며 상기 한 쌍의 배출포트를 통해 배출되는 냉매를 팽창시키는 팽창통로가 형성된다.
