    Abstract: A multi-stage thermal management system includes a fluid loop configured to supply a chilled heat transfer fluid to a plurality of thermal loads having different cooling demands. The system includes a plurality of heat rejection components arranged in stages and fluidly coupled to the fluid loop. The plurality of heat rejection components is configured to receive a return heat transfer fluid from the plurality of thermal loads and extract heat from the return heat transfer fluid to generate the chilled heat transfer fluid. A control system is configured to selectively draw the chilled heat transfer fluid from each heat rejection component individually and to direct the chilled heat transfer fluid to the plurality of thermal loads based on the different cooling demands of the plurality of thermal loads to meet each of the different cooling demands via supply of the chilled heat transfer fluid.

    Abstract: A squeeze film damper assembly (100) for a compressor (12) includes a damper sleeve (112) configured to be disposed about a rotor shaft (72) of the compressor (12). The damper sleeve (112) includes a pressure dam pocket (166) formed in an inner circumference (145) of the damper sleeve (112). The pressure dam pocket (166) is configured to receive a flow of lubricant (24) and to pressurize the flow of lubricant (24) via rotation of the rotor shaft (72). The damper sleeve (112) includes an outlet passage (142) extending from the pressure dam pocket (166) to an outer circumference (134) of the damper sleeve (112). The squeeze film damper assembly (100) also includes a bearing housing (110) disposed about the damper sleeve (112) to form a damper gap (116) extending between the outer circumference (134) of the damper sleeve (112) and the bearing housing (110). The damper gap (116) is fluidly coupled to the outlet passage (142) and is configured to receive the flow of lubricant (24) from the pressure dam pocket (166).

    Abstract: A compressor includes a diffuser passage configured to receive refrigerant flow from an impeller of the compressor, where the diffuser passage is at least partially defined by a compressor discharge plate of the compressor. The compressor also includes a variable geometry diffuser positioned within the diffuser passage and configured to adjust a dimension of a refrigerant flow path through the diffuser passage, an actuator coupled to the variable geometry diffuser and configured to adjust a position of the variable geometry diffuser within the diffuser passage, and a controller configured to regulate operation of the actuator, The controller is configured to instruct the actuator to adjust the position of the variable geometry diffuser from a first position to a second position using a first force and to adjust the position of the variable geometry diffuser from the second position to a third position using a second force less than the first force, where the variable geometry diffuser abuts the compressor discharge plate in the third position.

    Abstract: A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a first refrigerant circuit (102) having a first compressor (106) configured to circulate a first refrigerant through a first condenser (110) and a first evaporator (108), a second refrigerant circuit (104) having a second compressor (114) configured to circulate a second refrigerant through a second condenser (118) and a second evaporator (116), and a heat exchanger (126) configured to place the first refrigerant in a heat exchange relationship with the second refrigerant. The first refrigerant circuit is configured to direct the first refrigerant from the first condenser to the heat exchanger and from the heat exchanger to the first evaporator, and the second refrigerant circuit is configured to direct the second refrigerant from the second condenser to the heat exchanger and from the heat exchanger to the second evaporator.

    Abstract: Embodiments of the present disclosure are directed to a coating apparatus including a spray applicator configured to discharge a coating material toward a surface of a workpiece, wherein the spray applicator includes an air shaping orifice, and wherein the spray applicator is configured to generate an electric field between the spray applicator and the workpiece and a positioning system configured to adjust a position of the spray applicator relative to the surface of the workpiece. The coating apparatus further includes a control system configured to regulate operation of the spray applicator and/or the positioning system to: maintain the spray applicator within a coating distance between 20 millimeters and 100 mm from the surface of the workpiece during spray operations of the spray applicator, maintain a flow rate of shaping air through the air shaping orifice between 150 normal liters per minute (Nl/min) and 300 Nl/min during spray operations of the spray applicator, and maintain an electrical potential of the electric field between 30 kilovolts (kV) and 40 kV during spray operations of the spray applicator.

    Abstract: The present disclosure relates to a compressor (32) having a first rotor (76) and a second rotor (78) disposed within a housing (30), where the first rotor (76) is configured to rotate about a first axis (96) of the housing (30) and the second rotor (78) is configured to rotate about a second axis (98) of the housing (30). The first rotor (76) and the second rotor (78) engage with one another such that rotation of the first rotor (76) and the second rotor (78) pressurizes a vapor within the housing (30). The compressor (32) includes an end plate (80) coupled to a discharge end (33) of the housing (30), where the end plate (80) includes a variable opening (100) configured to discharge a flow of the vapor from the housing (30). The end plate (80) also includes a first movable member (102) and a second movable member (104) that are configured to increase or decrease a cross-sectional area of the variable opening (100) to adjust the flow of the vapor.
