Abstract: A vapor compression system (200; 300; 400) comprising: 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.

Abstract: A vapor compression system (200; 400; 600; 700; 800; 900; 1000) comprises a plurality of valves (260, 262, 264; 260) controllable to define a first mode flowpath and a second mode flowpath. The first mode flowpath is sequentially through: a compressor (22); a first heat exchanger (30); a first nozzle (228; 624); and a separator (48), and then branching into: a first branch returning to the compressor; and a second branch passing through an expansion device (70) and a second heat exchanger (64) to the rejoin the flowpath between the first heat exchanger and the separator. The second mode flowpath is sequentially through: the compressor; the second heat exchanger; a second nozzle (248; 625); and the separator, and then branching into: a first branch returning to the compressor; and a second branch passing through the expansion device and first heat exchanger to the rejoin the flowpath between the first heat exchanger and the separator.

Abstract: A refrigerated system includes a vapor compression system defining a refrigerant flow path and a heat recovery system defining a heat recovery fluid flow path. The heat recovery system is thermally coupled to the vapor compression system. The heat recovery system includes a first heat exchanger within which heat is transferred between a heat recovery fluid and an engine coolant and at least one recovery heat exchanger positioned along the heat recovery fluid flow path directly upstream from the first heat exchanger.

Abstract: A refrigerated system includes a heat recovery system defining a heat recovery fluid flow path. The heat recovery system includes an ejector having a primary inlet and a secondary inlet and a first heat exchanger within which heat is transferred between a heat recovery fluid and a secondary fluid. The first heat exchanger is located upstream from the primary inlet of the ejector. A second heat exchanger within which heat is transferred from a heat transfer fluid to the heat recovery fluid is upstream from the secondary inlet of the ejector. At least one recovery heat exchanger is positioned along the heat recovery fluid flow path directly upstream from the first heat exchanger.
