摘要： An ejector has a primary inlet (40), a secondary inlet (42), and an outlet (44). A primary flowpath extends from the primary inlet to the outlet. A secondary flowpath extends from the secondary inlet to the outlet. A mixer convergent section (114; 300; 400) is downstream of the secondary inlet. A motive nozzle (100) surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle has a throat (106) and an exit (110). An actuator (204) is coupled to the motive nozzle to drive a relative streamwise shift of the exit and convergent section.

摘要： A system has a compressor (22, 412). A heat rejection heat exchanger (30) is coupled to the compressor to receive refrigerant compressed by the compressor. The system has a heat absorption heat exchanger (64). The system includes a separator (170) comprising a vessel having an interior. The separator has an inlet, a first outlet, and a second outlet. An inlet conduit may extend from the inlet and may have the conduit outlet positioned to discharge an inlet flow into the vessel interior to cause the inlet flow to hit a wall before passing to a liquid refrigerant accumulation in the vessel.

摘要： An ejector (200; 300; 400; 600) has a primary inlet (40), a secondary inlet (42), and an outlet (44). A primary flowpath extends from the primary inlet to the outlet. A secondary flowpath extends from the secondary inlet to the outlet. A mixer convergent section (114) is downstream of the secondary inlet. A motive nozzle (100) surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle has an exit (110). A secondary inlet passageway along the secondary flowpath has a terminal portion oriented to discharge a secondary flow along the secondary flowpath at an angle of less than 75° off-parallel to a local direction of the primary flowpath.

The second portion is returned to the compressor. The ejector (66) has a primary inlet (70) coupled to the means to receive a first flow of the reduced enthalpy refrigerant. The ejector has a secondary inlet (72) and an outlet (74). The outlet is coupled to the first compressor to return refrigerant to the first compressor. A first heat absorption heat exchanger (80) is coupled to the economizer to receive a second flow of the reduced enthalpy refrigerant and is upstream of the secondary inlet of the ejector. A second heat absorption heat exchanger (90) is between the outlet of the ejector and the first compressor.
