Abstract
A sub-cooled condenser for an air conditioning system, having a condenser portion, a sub-cooler portion located below that of the condenser portion, an adjacent receiver tank having a first fluid port in hydraulic connection with the condenser portion and a second fluid port in hydraulic connection with the sub-cooler portion, and a refrigerant diverter assembly disposed in the receiver tank. The refrigerant diverter assembly is configured to divert a refrigerant from the first fluid port to a location beneath the surface level of a refrigerant retained within the receiver tank without impacting the surface level. The refrigerant diverter assembly includes a refrigerant port in hydraulic connection with the first fluid port, axial and annular refrigerant passageways, and a refrigerant conduit having an inlet end in hydraulic communication with the annular passageway and a second fluid port beneath the surface level (S) of the liquid phase refrigerant.
