The present invention relates to a ball valve, a heat pump system including the ball valve, and a control method thereof. The present invention includes a valve housing having three T-shaped openings and a ball having two different types of flow paths, and thus can control the flow of a refrigerant in up to six modes. Accordingly, the present invention can reduce the number of expansion valves applied to the heat pump system, thereby simplifying the control algorithm and the circuit shape of the refrigerant and reducing the manufacturing costs.

    La présente invention concerne un robinet à tournant sphérique, un système de pompe à chaleur comprenant le robinet à tournant sphérique, et son procédé de commande. La présente invention comprend un boîtier de soupape ayant trois ouvertures en forme de T et une bille ayant deux types différents de trajets d'écoulement, et peut ainsi commander l'écoulement d'un fluide frigorigène dans jusqu'à six modes. Par conséquent, la présente invention peut réduire le nombre de détendeurs appliqués au système de pompe à chaleur, ce qui simplifie l'algorithme de commande et la forme de circuit du fluide frigorigène et réduit les coûts de fabrication.

    본 발명은 볼밸브 및 볼밸브를 포함하는 히트펌프 시스템과 그 제어방법에 관한 것이다. 본 발명은 T자 형태의 개구부 3개를 갖는 밸브 하우징과 2개의 서로 다른 형태의 유로를 갖는 볼을 포함함으로써 최대 6가지 모드로 냉매 유동을 제어할 수 있고, 이에 따라 열펌프 시스템에 적용되는 팽창밸브의 수를 감축하여 제어 알고리즘 및 냉매의 서킷 형상을 단순화 하고, 제작비용을 절감할 수 있는 효과가 있다.
