摘要： A porous gas bearing is disclosed. The porous gas bearing includes a housing having a fluid inlet and an aperture. A porous surface layer is disposed within the housing surrounding the aperture in a circumferential direction. The porous surface layer includes a plurality of segments arranged in a longitudinal direction of the aperture. The porous surface layer is in fluid communication with the fluid inlet. A damping system includes a plurality of dampers. The plurality of dampers is disposed circumferentially about the aperture. The plurality of dampers is arranged in between a first segment of the plurality of segments of the porous surface layer and a second segment of the plurality of segments of the porous surface layer.

摘要： A system includes first and second compressors arranged in parallel, a condenser, expansion device, evaporator, and flow control device fluidly connected. The first compressor includes a first lubricant sump and the second compressor including a second lubricant sump. A lubricant transfer conduit fluidly connects the first lubricant sump and the second lubricant sump. The flow control device is disposed between the evaporator and the first and second compressors, and includes a fluid inlet and two fluid outlets. A first of the two fluid outlets is fluidly connected to the first compressor, a second of the two fluid outlets is fluidly connected to the second compressor. The second fluid outlet includes a nozzle disposed within a flow passage of the flow control device such that a space is maintained between an outer surface of the nozzle and an inner surface of the flow passage.

摘要： A compressor driven by a variable-frequency drive (VFD) is provided to supplement operation of another compressor of a heating, ventilation, air conditioning, and refrigeration (HVACR) system, such as heat pump operations at low ambient temperatures. The VFD is controlled to provide efficient pressure ratios for each compressor of the HVACR system when the compressor driven by the VFD is used to supplement the other compressor. The compressor driven by the VFD can be included as a built-in compressor of the HVACR system or added subsequently as part of a booster package.
