ABSTRACT:
A replaceable float oil separator, for installation in large refrigeration systems of the vapor compression type using refrigerant-immiscible lubrication oils, comprises a compact float assembly that is disposed transversely to the axis of its vessel and a removal assembly on the side of the vessel through which the float assembly can be removed for repair or replacement. The float assembly is compact in its design because a counterweight supports up to 90%, preferably 60%, of the weight of the float ball, in accordance with an energy balance equation. The removal assembly includes a flange cover, an o-ring, and a flange which is attached to the cylindrical side of the vessel, near its bottom where temperature cycling is minimal, whereby the vessel is semi-hermetically sealed. The float assembly is entirely supported by its oil return line which is attached to and passes through the flange cover of the removal assembly. Because the oil return line is off-centeredly disposed in the flange cover, the float assembly can be replaced only in its correct operating position when the flange cover is bolted onto the flange.
