← TechnologyWhich outcome occurs when hermetic refrigeration compressor experiences sustained liquid floodback of refrigerant?
A)Bearing damage from lubricant washout✓
B)Reduced cooling from excessive pressure
C)Increased efficiency from lower temperatures
D)Decreased capacity due to valve closure
💡 Explanation
When liquid refrigerant floods back, lubricant washout occurs because liquid refrigerant dilutes the compressor oil, reducing its lubricating properties contributing to bearing wear. Therefore bearing can be damaged, rather than pressure change, increased efficiency, or valve closure which require different operational triggers.
