Sealed system for an appliance
A sealed system for an appliance includes a compressor having a shell and lubrication oil disposed with the shell. A condenser in fluid communication with the compressor such that compressed refrigerant from the compressor flows to the condenser during operation of the compressor. The sealed system also includes a heat exchanger for cooling the lubrication oil during operation of the compressor.
1. A scaled system for an appliance, comprising:
a compressor comprising a shell and a lubrication oil disposed with the shell;
a condenser in fluid communication with the compressor such that compressed refrigerant from the compressor flows to the condenser during operation of the compressor;
a condenser fan configured for selectively urging a flow of air across the condenser; and
a heat exchanger positioned adjacent the condenser fan, the heat exchanger being in fluid communication with the compressor such that lubrication oil from the compressor flows to the heat exchanger during operation of the compressor.
2. The sealed system of claim 1 , further comprising a refrigeration conduit that extends between the compressor and the condenser and a lubrication oil conduit that extends between the compressor and the heat exchanger, the refrigeration conduit directing compressed refrigerant from the compressor to the condenser during operation of the compressor, lubrication oil conduit directing lubrication oil from the compressor to the heat exchanger during operation of the compressor.
3. The sealed system of claim 1 , wherein the compressor further comprises a pump, the pump operable to urge a flow of lubrication oil from the compressor to the heat exchanger during operation of the compressor.
4. The sealed system of claim 1 , wherein the compressor further comprises a pump, the shell of the compressor comprising an inlet conduit and an outlet conduit, the pump coupled to the outlet conduit such that the pump is operable to urge a flow of lubrication oil from the compressor to the heat exchanger via the outlet conduit, the inlet conduit configured for receiving the flow of lubrication oil from the heat exchanger, the inlet conduit extending to a cylinder of the compressor to direct the flow of lubrication oil from the beat exchanger to the cylinder.
5. The sealed system of claim 4 , wherein the inlet conduit defines an auxiliary outlet disposed above a motor of the compressor.
6. The sealed system of claim 1 , wherein the compressor further comprises a pump, the shell of the compressor comprising an inlet conduit and an outlet conduit, the pump in fluid communication with the inlet conduit and the outlet conduit, the inlet conduit configured for receiving the flow of lubrication oil from the heat exchanger and directing the flow of lubrication oil from the heat exchanger into a sump of the shell, the outlet conduit extending from a cylinder of the compressor to direct the flow of lubrication oil from cylinder to the heat exchanger.
7. The sealed system of claim 6 , further comprising an auxiliary conduit extending from the pump and having an outlet disposed above a motor of the compressor.
8. The sealed system of claim 1 , wherein the heat exchanger is configured for cooling the lubrication oil from the compressor during operation of the compressor.
9. The scaled system of claim 1 , wherein the heat exchanger is positioned such that the condenser fan urges air across the heat exchanger during operation of the condenser fan.
