Abstract
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a compressor configured to circulate a working fluid along a working fluid circuit, a bearing disposed about a shaft of the compressor, and a fluid supply system configured to direct a portion of the working fluid from the working fluid circuit to the bearing, where the bearing is configured to discharge the portion of the working fluid toward the shaft.
Claims20
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a compressor configured to circulate a working fluid along a working fluid circuit;
- a bearing disposed about a shaft of the compressor;
- and
- a fluid supply system configured to direct a portion of the working fluid from the working fluid circuit to the bearing,
- wherein the bearing is configured to discharge the portion of the working fluid toward the shaft.
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a working fluid circuit comprising a compressor, an evaporator, and a condenser, wherein the compressor is configured to circulate a working fluid along the working fluid circuit;
- a bearing assembly of the compressor, wherein the bearing assembly is disposed about a shaft of the compressor, the bearing assembly comprises a plurality of radial bearing segments arrayed about a circumference of the shaft, and each radial bearing segment of the plurality of radial bearing segments comprises a porous material;
- and
- a fluid supply circuit extending from the working fluid circuit to the bearing assembly, wherein the fluid supply circuit is configured to direct a flow of the working fluid from the working fluid circuit to the bearing assembly.
A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a bearing configured to be disposed about a shaft of a compressor, wherein the bearing comprises a porous material, and the bearing is configured to discharge a flow of fluid through the porous material and toward the shaft of the compressor;
- and
- a fluid supply system configured to direct the flow of fluid from a working fluid circuit of the HVAC&R system to the bearing,
- wherein the fluid supply system is configured to supply the flow of fluid to the bearing in a liquid phase, and the bearing is configured to discharge the flow of fluid toward the shaft in a vapor phase.
