Tech tips : What happens when oil starts to accumulate inside the AC unit?

Let’s take a look at what if refrigeration oil accumulates inside the cycle of AC Unit

Oil may accumulate inside the cycle in case of the things listed below.

- If the “Pump Down” procedure wasn’t done properly
- If the compressor was replaced

Every time when the compressor gets changed, around 40c.c of oil could accumulate within the cycle.

We have tested a device with the condition specs.

AC Type : Split Wall Mount

Oil Amount(Spec: 280c.c)
-   Case 1 : 280c.c
-   Case 2 : 320c.c
Test condition : cooling standard (27/19 35/24)
Compressor Model : LG Inverter Rotary compressor

Depending on oil amount, how big do you think the difference will be?

The results are as follows. The differences were significant enough to cause confusion between the results.
