Hi-
I'm new on the site, but it looks like a great resouce and to be honest I'm still pretty green in the commercial area.
I was wondering if anyone has experienced an oil migration problem like this: Carrier 19XR centrifugal 1500 ton R-134a machine loses oil gradually when it is shut down over the winter.
This past spring I had to add about 10 gallons of POE then remove it all after the stuff that migrated came back. Now that the cold is here, I am seeing the same thing happen. The chiller hasn't run for a couple of weeks now and the oil level in the sump has dropped below the lower sight glass.
We have a 30 minute "flush" through the condenser barrel every night to keep solids in suspension, but other than that the machine is completely idle. Any thoughts?
