Why Compressors Fail - Flooded Starts
23 November 2009
This is Part 2 of a new article series from Danfoss called 'Why Compressors Fail'. The series will evidently focus on what causes compressor failure and how it can be handled.
Flooded starts are probably the major cause of compressor failures. Flooded starts occur when liquid refrigerant has migrated from the system and condensed into the compressor oil. Migration can occur in all systems up to a point, due to the vapour pressure of the refrigerant being greater than the vapour pressure of the oil.
