← ScienceWhich outcome results when a refrigeration compressor exceeds its engineered superheat limits?
A)Vapor compression inefficiency
B)Oil breakdown and reduced lubrication✓
C)Evaporator coil ice blockage
D)Condenser subcooling optimization
💡 Explanation
Excessive superheat leads to high discharge temperatures where thermal decomposition of lubricating oil occurs; this is the mechanism of thermal cracking . Because the oil's viscosity declines rapidly, lubrication fails; therefore, bearing wear accelerates, rather than efficiency increasing as in option D.
