Trane Chiller: Noisy Oil Separator

[hoodemar]

No NickName i do not think the design could be wrong we have four chillers on the site and am sure not all can be wrong.

hoodemar yes there is oil in the separator as checked with the 1/4" hoses and sight glass

at my problem, oil was completely going to the evaporator and there was a pipe 1/4" was comming from evap to compressor. also there is a small filter on this line. Oil filter was dirty and this small filter was dirty. so oil was not turning back to the separator and separotor was completely empty.

ur situation is different, because u have oil in separator. is there any mesh? did u see anything in the drier filter? or in the oil filter?

I use to work on these alot and trying to get my memory together, make sure all the service valves for oil flow are open. From memory if one service is closed it will restrict oil flow and cause the bearing to whine loud. When checking oil level, make sure all valves are open and there is no ***** pressure boiling off differential in the system. Let the oil level stablize in your ***** hose sight glass for 15 minutes. If you are for sure there is the right amount volume of oil, then my very last thought is the centrifugal baffles are loose.
