  • 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?
