Abstract
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes a working fluid circuit including an evaporator, a condenser, and a compressor. The HVAC&R system also includes a fluid supply system including a lubricant circuit configured to direct a flow of working fluid from the working fluid circuit to a bearing of the compressor. The lubricant circuit includes a heat exchanger configured to place the flow of working fluid in a heat exchange relationship with a cooling fluid.
Claims20
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- a working fluid circuit comprising an evaporator, a condenser, and a compressor;
- and
- a fluid supply system comprising a lubricant circuit configured to direct a flow of working fluid from the working fluid circuit to a bearing of the compressor, wherein the lubricant circuit comprises a heat exchanger configured to place the flow of working fluid in a heat exchange relationship with a cooling fluid.
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- a working fluid circuit comprising a condenser, an evaporator, and a compressor, wherein the working fluid circuit is configured to circulate a working fluid therethrough;
- a lubricant circuit configured to direct a portion of the working fluid from the working fluid circuit to a bearing of the compressor;
- a heat exchanger disposed along the lubricant circuit between the working fluid circuit and the bearing, relative to a flow direction of the portion of the working fluid along the lubricant circuit;
- a cooling fluid circuit configured to circulate a cooling fluid through the heat exchanger, wherein the heat exchanger is configured to facilitate heat transfer from the portion of the working fluid to the cooling fluid;
- and
- a pump disposed along the lubricant circuit and configured to direct the portion of working fluid from the heat exchanger to the bearing.
A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system, comprising:
- a condenser disposed along a working fluid circuit;
- a compressor disposed along the working fluid circuit, wherein the compressor comprises a bearing;
- and
- a heat exchanger of a lubricant circuit, wherein the heat exchanger is configured to receive a flow of working fluid from the condenser and to place the flow of working fluid in a heat exchanger relationship with a cooling fluid, wherein the lubricant circuit is configured to direct the flow of working fluid from the heat exchanger to the bearing.
