Abstract
Refrigerant charging systems and methods of use are described herein. A refrigerant charging system may include a conduit, a valve releasably connectable to the outlet portion and coupled to a first end of the conduit; and a disconnect coupler fitting connected to a second end of the conduit. The disconnect coupler fitting may include a control structure positioned in a hollow body that, during use, allows refrigerant flow to the refrigerant circuit. The control structure may include one or more openings that allow controlled leakage of fluid from the refrigerant charging assembly when the refrigerant charging assembly is disconnected from at least the refrigerant service unit.
