Abstract
Ease of service is provided in an integrated condenser (20) and receiver (22) including two nonhorizontal headers (24), a plurality of tubes (28) extending between the headers (24) to establish a plurality of hydraulically parallel flow pads between the headers (24); at least one partition (48, 50, 52) in each of the headers for causing refrigerant to make at least two passes, including an upstream pass and a downstream pass, through the condenser (20); and an elongated receiver (22) mounted on one of the headers (24). The elongated receiver (22) includes an interior chamber (61), an upper inlet (70) connected to a downstream side of the upstream pass for the flow of refrigerant form the upstream pass to the interior chamber (61), a lower liquid outlet (71) connected to an upstream side of the downstream pass for the flow of liquid refrigerant from the interior chamber (61) to the downstream pass, and a port (62) to allow access to interior chamber (61) for servicing the receiver (22). The port (62) includes a first nominally cylindrical interior surface (80), a second nominally cylindrical interior surface (82) spaced axially and radially outward from the first cylindrical interio…
