Patent number: 10352592Abstract: A vapor compression system (200; 300; 400) has: a compressor (22); a first heat exchanger (30); a second heat exchanger (64); an ejector (38); separator (48); and an expansion device (70). A plurality of conduits are positioned to define a first flowpath sequentially through: the compressor; the first heat exchanger; the ejector from a motive flow inlet through (40) an outlet (44); and the separator, and then branching into: a first branch returning to the compressor; and a second branch passing through the expansion device and second heat exchanger to a secondary flow inlet (42). The plurality of conduits are positioned to define a bypass flowpath (202; 302; 402) bypassing the motive flow inlet and rejoining the first flowpath at essentially separator pressure but away from the separator.Type: GrantFiled: May 26, 2016Date of Patent: July 16, 2019Assignee: Carrier CorporationInventors: Alexander Lifson, Zuojun Shi, Hans-Joachim Huff, Parmesh Verma, Thomas D.

Patent number: 9696069Abstract: An ejector has a primary inlet, a secondary inlet, and an outlet. A primary flowpath extends from the primary inlet to the outlet and a secondary flowpath extends from the secondary inlet to the outlet, merging with the primary flowpath. A motive nozzle surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle has a throat and an exit. In one group of embodiments, an effective area of the exit is variable. In others, the needle may extend downstream from a flow control portion or may have an upstream convergent surface of a flow control portion.Type: GrantFiled: March 14, 2016Date of Patent: July 4, 2017Assignee: Carrier CorporationInventors: Hongsheng Liu, Jiang Zou, Frederick J.
