A ball valve assembly according to the present invention comprises: a valve body having a first inlet/outlet, a second inlet/outlet, an internal flow path, a ball chamber, a stem installation hole, a moisture indicator mounting groove, and a refrigerant injection hole; a first and a second connecting pipe coupled to both ends of the valve body; a ball installed to be able to rotate in a ball chamber; a stem installed to be able to rotate in the stem installation hole so as to be coupled to the ball; a moisture indicator having a moisture detecting member and a lens assembly; and a refrigerant injector coupled to the valve body so as to be connected to the refrigerant injection hole, wherein the moisture detecting member is discolored when touching moisture contained in refrigerant, and the lens assembly having a lens is coupled to the moisture indicator mounting groove and seals the moisture indicator mounting groove. In the ball valve assembly according to the present invention, the moisture indicator detecting the moisture contained in the refrigerant is integrally mounted at the ball valve for switching the flow of the refrigerant flowing along a refrigerant pipe so that overall manufacturing costs and management costs for the refrigeration cycle apparatus are reduced. |
