Why Compressors Fail - Refrigerant Flood Back
16 November 2009
This is Part 1 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.
Refrigerant flood back occurs during the running cycle of the machine. This is where large volumes of liquid refrigerant are returned to the running compressor down through the Suction pipe work, in an uncontrolled manner. Depending on the degree of liquid returning to the compressor, determines as to what damage will occur. This can often be seen as foaming in the compressors’ oil level sight glass.
