i have a 3 pipe vrv system that i have replaced the compressor on a week ago, i fitted liquid and suction driers as this is the second compressor to be fitted. ( last one lasted 12 months) it appears that oil return is very slow and on draining the oil from the original compressor it only had approx 1/2 l of oil very black looked like its out of an old diesel engine. (original charge 2.5l) The unit suffered a major leak (tripped high discharge temp) on friday from a prevously reparied joint (by others).
My question is if i remove the oil seerator and drain what i suspect to be a lot of oil can i replace the oil filter that is installed to protect the capilery with an acid absorbing liquid line drier. and then replenish with new oil.
As this unit is on R22 they are already looking into replacing the existing plant over the next couple of years.
many thanks.
