← TechnologyWhich risk increases when high compression ratio occurs within scroll compressors?
A)Excessive lubricant film breakdown✓
B)Decreased refrigerant subcooling capacity
C)Increased compressor motor slip
D)Reduced volumetric efficiency gained
💡 Explanation
Excessive compression causes elevated temperatures where lubricant viscosity decreases, leading to boundary lubrication rather than hydrodynamic; therefore, film breakdown increases and bearing wear accelerates because heat weakens the lubricant, rather than directly affecting refrigerant cooling.
