← TechnologyWhich outcome occurs when a scroll compressor in a refrigeration system experiences oil slugging?
A)Bearing failure due to poor lubrication✓
B)Increased cooling capacity temporarily observed
C)Reduced motor current and overheating
D)Uniform pressure rise during compression
💡 Explanation
Bearing failure occurs because oil slugging introduces incompressible liquid into the compressor, damaging its internal components through hydraulic lock. This happens rather than enhancing function; therefore, bearings fail due to lack of lubrication, as the oil pump can't cope with the excess fluid.
