Point to consider at compressor exchange
1) Oil color decision (availability of that change compressor that is beside at the same time) of compressor that broke down.
- Decide that exchange all 2 that exchange side that broke down after judge state of oil by below photograph color
extracting oil in compressor that broke down in case of exchange compressor.
- ASTM = exchange all 2 more than 3.
- Normalcy Clamping force of bolt that x compressor is 3 ± 0.5 N-m.
2) Weight of compressor and quantity of oil
- When compressor is shipped at factory, oil of (compressor unit standard) 1100cc was lled up.
- GB052FAVA of weight of compressor including oil is 31.6kg, and GB066FAVA is 35.4kg.
- Add oil to outdoor unit as much as relevant weight if is heavy than weight of compressor that weight of compressor that
is changed to locality is changed newly.
- Quantity(kg) of added oil = Weight(kg) of compressor that broke down - Weight(kg) of newly change compressor
- If quantity of calculated addition oil passes over 1kg, quantity of add oil does by 1kg.
- Problem of that is blocked in oil circulation of (remaining oil of compressor that broke down below 0.3kg) compressor if is light
more than 0.8kg than weight of compressor that weight of compressor that is changed to locality is changed newly inspects oil
circulating system because possibility occurred is high.
3) Checking of oil circulating system
①
Oil separator capillary tube or lter of block
- If lter or capillary tube of oil separator lower column is blocked by alien substance etc.., can become cause of compressor breakdown
because oil is not collected.
- Can doubt that is blocked if oil separator capillary tube temperature is low after refrigerant outlet temperature of compressor, in driv-
ing, rises.
(
※
Compressor 2 individual occasion oil separator capillary tubes each other cross.)
- Conrm that is blocked in stationary state through nitrogen pressurization availability.
②
Breakdown of Accum Oil Return Valve (ARV)
- Damage can become cause of compressor breakdown because oil is not collected if lter of valve front/piping etc.. is blocked
with ARV is closed.
- Power connector of ARV conrms that was linked right.
- Extract connector in vacuum mode or conrm whether when insert, action sound of valve happens.
③
When CCH is badness, can become cause of compressor breakdown by oil foaming.
▶ Change to compressor that is beside.
