Abstract
A refrigerant receiver tank assembly having a refrigerant inlet flow path for receiving refrigerant from a condenser coil and a refrigerant outlet flow path for supplying refrigerant to an evaporator coil. The receiver tank assembly includes a tank and a manifold which define a closed space for holding a supply level of liquid refrigerant. The refrigerant inlet flow path includes an outlet opening in the closed space, and an inlet opening. The manifold defines the refrigerant outlet flow path, with the refrigerant outlet flow path having an inlet opening in the closed space, and first and second outlet openings. A pick-up tube is disposed in the closed space having a first end connected to the inlet opening of the refrigerant outlet flow path and a second end disposed below the level of liquid refrigerant in the closed space. A controllable valve is mounted on the manifold which selectively controls flow of refrigerant to a predetermined outlet opening of the refrigerant outlet flow path. In a preferred embodiment, an additional tubular member is disposed in the closed space having a first end connected to the refrigerant inlet flow path and a second end disposed above the liquid l…
