← TechnologyWhich process leads to a reduced cooling capacity when liquid refrigerant enters the compressor?
A)Bearing wear and lubrication failure
B)Slug formation leading to inefficiency✓
C)Excessive superheat temperature instability
D)Oil foaming causing mass restrictions
💡 Explanation
Refrigerant slugging causes damage because incompressible liquid entering the compressor prevents piston displacement; this is a consequence of excessive subcooling. Therefore, cooling capacity decreases substantially, rather than experiencing bearing wear, superheat instability, or oil problems. Refrigerant flooding also contributes during compressor’s startup.
