    Abstract: An ejector refrigeration circuit (1), which is configured for circulating a refrigerant, in particular carbon dioxide, comprises at least two controllable ejectors (6, 7), which are connected in parallel and respectively comprise a primary high pressure input port (6a, 7a), a secondary low pressure input port (6b, 7b) and an output port (6c, 7c); and a control unit (28), which is configured for operating the ejector refrigeration circuit (1) employing a method which comprises the steps of: a) operating a first ejector (6) of the at least two controllable ejectors (6, 7) by controlling the opening of its high pressure port (6a) until the maximum efficiency of said first ejector (6) has been reached or the actual refrigeration demands are met; b) operating at least one additional ejector (7) of the at least two controllable ejectors (6, 7) by opening its primary high pressure input port (7a) for increasing the refrigeration capacity of the ejector refrigeration circuit (1) in case the actual refrigeration demands are not met by operating the first ejector (6) alone.

    Abstract: An ejector-type refrigeration cycle device is provided with a first ejector (15) which draws refrigerant from a refrigerant suction port (15b, 24b) by using a high-speed refrigerant flow jetted from a nozzle part (15a, 24a), and a first suction-side evaporator (19) connected to the refrigerant suction port (15b) of the first ejector (15), and a second suction-side evaporator (27) connected to a refrigerant suction port (24b) of a second ejector (24). A flow amount of the refrigerant in the second ejector (24) is smaller than a flow amount of the refrigerant in the first ejector (15). The refrigerant branched at a branch part (Z2) that is positioned on a downstream refrigerant side of a radiator (13) and on an upstream refrigerant side of the first ejector (15) flows into the second ejector (24), and the refrigerant branched on a downstream refrigerant side of the second ejector (24) flows into the second suction-side evaporator (27).

    Abstract: A compressor (22) has a housing assembly (40) with a suction port (24), a discharge port (26), and a motor compartment (60). An electric motor (42) has a stator (62) within the motor compartment and a rotor (64) within the stator. The rotor is mounted for rotation about a rotor axis (500). One or more working impellers (44) are coupled to the rotor to be driven by the rotor in at least a first condition so as to draw fluid in through the suction port and discharge the fluid from the discharge port. An inlet guide vane (IGV) array (174) is between the suction port (24) and the one or more impellers (44). One or more bearing systems (66, 68) support the rotor (64) and/or the one or more impellers (44). One or more main drain passages (120, 234 206; 120, 232, 202, 206) are coupled to the bearings to pass fluid along a drain flowpath from the bearings to a location (172) upstream of the impeller and downstream of the IGV array.

    Abstract: A defrost refrigeration system having a main refrigeration system and comprising a first line extending from a compressing stage to an evaporator stage and adapted to receive refrigerant in high-pressure gas state from the compressing stage. A first pressure reducing device on the first line is provided for reducing a pressure of the refrigerant in the high-pressure gas state to a second low-pressure gas state. Valves are provided for stopping a flow of the refrigerant in a first low-pressure liquid state from a condensing stage to evaporators of the evaporator stage and directing a flow of the refrigerant in the second low-pressure gas state to release heat to defrost the evaporators and thereby changing phase at least partially to a second low-pressure liquid state. A second line is provided for directing the refrigerant having released heat to the compressing stage, the condensing stage or the evaporator stage.
