oil fouling/oil migration/lubricant migration Explanation: This article seems as if it could be what you are looking for. http://www.powerknot.com/about_oil_fouling.html -------------------------------------------------- Note added at 1 hr (2014-05-30 16:19:01 GMT) -------------------------------------------------- Slugging may also be a solution: "Liquid refrigerant slugging: Liquid slugging is the term used to describe the passage of liquid refrigerant and oil through the compressor’s suction and discharge valves. It is evidenced by a loud metallic clatter inside the compressor, possibly accompanied by extreme vibration of the unit. Slugging can result in broken valves, blown head gaskets, broken connecting rods, and other major component damage. Slugging frequently occurs on start-up, when liquid refrigerant has migrated to the compressor. On some units, because of the tubing configuration and location of the components, liquid refrigerant and oil can collect in the suction line or evaporator during the off-cycle, returning to the compressor as a *solid liquid* with extreme velocity on start-up. The velocity and the weight of the liquid slug may be of sufficient magnitude to override any internal anti-slug protection devices designed within the compressor, again causing major damage. " |
