Which outcome is most likely when a refrigeration cycle compressor experiences superheated vapor return?

A)Overheating and shortened lifespan
B)Reduced cooling and icing of coils
C)Increased energy efficiency overall
D)Vapor lock in expansion devices

💡 Explanation

When excessive superheat occurs, the compressor overheats because the refrigerant absorbs heat beyond its intended saturation point, reducing lubrication. This extended exposure damages components like the motor windings, shortening the its operational lifespan. Therefore, overheating results, rather than improved efficiency, iced coils, or choked flow requiring different refrigerant states.
