Which risk greatly increases when an inefficient refrigeration cycle attempts maintaining deep cryo-temperatures?

💡 Explanation

Compressor overheating risks raise sharply because inefficient heat removal results in greater work input, meaning significant compression heating via isentropic compression; therefore compressor failure is imminent rather than ice formation, a drop in coefficient of performance, or reversed flow.
