Which outcome occurs when a positive displacement refrigerant pump experiences significant liquid slugging?

💡 Explanation

When a refrigerant pump experiences liquid slugging, hydraulic shock occurs because incompressible liquid impacts pump components, leading to bearing damage and lubricant washout. Therefore bearing failure results, rather than subcooling reduction, superheat increase or flow reduction which require different refrigerant cycle issues.
