Which outcome occurs when heat input surpasses a refrigerator's thermal capacity?

A)Compressor oil viscosity decreases rapidly
B)Refrigerant subcooling significantly increases
C)Evaporator temperature remains stable
D)Condenser pressure decreases rapidly

💡 Explanation

Increased heat causes overheating, pushing the compressor beyond design. The **lubrication breakdown** affects sealing and thus volumetric efficiency because oil thins as temperature climbs; therefore, the viscosity drops rather than refrigerant gains subcooling under increased boiling point operational risk.
