Which consequence results when a refrigerator's vapor-compression cycle becomes irreversible?

💡 Explanation

Irreversibilities increase entropy, diminishing the cooling effect via a less efficient use of energy; degradation therefore reduces effective heat transfer and thus lowers COP due to heat generation that cannot be reversed, rather than specific phase-change failures or over-pressure scenarios.
