Which condition reduces net work output during refrigeration cycles?

💡 Explanation

Lower efficiency increases entropy generated. Increased entropy reduces useful refrigerator expansion because irreversibilities consume free energy during compression, therefore reducing net work transferred rather than increasing evaporator cooling. Subcooling helps; superheating has mixed effects.
