Which effect is minimized when designing refrigeration cycles?

💡 Explanation

Irreversible heat transfer inefficiencies reduce a refrigeration cycle's Coefficient of Performance because entropy generation reduces cycle efficiency, therefore design minimizes this; rather than focusing on subcooling or superheating which optimize existing cycles.
