Which risk increases when operating a refrigeration cycle near its thermodynamic limit?

💡 Explanation

Icing risk increases because of moisture accumulation followed by rapid adiabatic cooling during throttling, a consequence of maximized ΔT across the expansion valve utilizing the Joule-Thomson effect; therefore icing, rather than the other options, prevents cycle completion rather than changing efficiency.
