    摘要： A double-pipe heat exchanger capable of achieving a compact configuration and suppressing a liquid refrigerant contained in a gas-liquid two-phase refrigerant from flowing out from an inner pipe so as to prevent generation of a liquid-back phenomenon is provided. A double-pipe heat exchanger (31) includes an outer pipe (32) through which a high pressure liquid refrigerant flows, and an inner pipe (33) having an inlet side end (33A) into which a low pressure gas-liquid two-phase refrigerant obtained by reducing pressure of the high pressure liquid refrigerant flows, and an outlet side end (33B) connected to a suction side part of a compressor. The double-pipe heat exchanger (31) includes a plurality of vertical pipes (34A, 34B) arranged in the up and down direction, and a curve pipe (35) connecting ends of the plurality of vertical pipes (34A, 34B), the outlet side end (33B) of the inner pipe (33) is provided in an upper end of one vertical pipe (34B), and the inlet side end (33A) of the inner pipe (33) is provided in an upper end of the other vertical pipe (34A).

    摘要： A sub-cooled condenser (100) for an air conditioning system, having a condenser portion (124), a sub-cooler portion (126) located below that of the condenser portion (124), an adjacent receiver tank (128) having a first fluid port (130) in hydraulic connection with the condenser portion (124) and a second fluid port (132) in hydraulic connection with the sub-cooler portion (126), and a refrigerant diverter assembly (200) disposed in the receiver tank (128). The refrigerant diverter assembly (200) is configured to divert a refrigerant from the first fluid port (130) to a location beneath the surface level of a refrigerant retained within the receiver tank (128) without impacting the surface level. The refrigerant diverter assembly (200) includes a refrigerant port (212) in hydraulic connection with the first fluid port (130), axial and annular refrigerant passageways (208, 210), and a refrigerant conduit (224) having an inlet end (232) in hydraulic communication with the annular passageway (210) and a second fluid port (132) beneath the surface level (S) of the liquid phase refrigerant.
