← TechnologyWhich outcome occurs when heat from a scroll compressor's motor windings exceeds the epoxy's thermal limit?
A)Refrigerant oil viscosity decreases sharply
B)Compressor's volumetric efficiency acutely increases
C)Winding insulation will structurally degrade✓
D)Bearing lubrication will temporarily improve
💡 Explanation
Winding insulation degrades because thermal decomposition increases exponentially with temperature (Arrhenius equation). Therefore, the insulation breaks down, rather than the temperature improving lubrication, or markedly improving compressor efficiency at thermal maximums if all components function.
