Tech/Engineering / air conditioning | | English term or phrase: oil equalizing | in a tale describing the technical features of an air conditioning unit:
piping connections:
- liquid
- gas
- oil equalizing
could you explain what sort of connection is this?
thanks! |

| | oil return pipe or tube between compressor sumps | Explanation:
In an air conditioner, refrigerator or other thermodynamic device, the oil is carried by the fluid (freon, formely R22, newer R134a or other fluids), which may be in two states in the system: liquid or gas, the operation of the device is precisely based on the change of state of this fluid.
As the oil is carried everychere by the fluid and is mainly needed in moving parts, most often the compressor is at the lowest point of the circuit (look at your refrigerator), in which case the oil naturally returns where it is the most useful.
But it may happen in some cases that this positioning of the compressor is not possible, or there are multiple compressors, in which case one may receive more returning oil than the other(s), then a specific pipe allows for "equalizing" of oil level.
I do not believe in the "oil pressure" interpretation, for small devices (I mean automotive or domestic air conditioners), there is no pressurized oil nor reservoir in the systems, only very big appliances have separate lubrication.
