Which efficiency limit occurs during an irreversible refrigeration cycle?

💡 Explanation

An irreversible refrigeration cycle leads to a reduced Coefficient of Performance because entropy generation increases during the cycle, which lessens useable cooling, therefore, COP falls rather than improves because other thermodynamic losses are increased.
