← ScienceWhich risk greatly increases when an inefficient refrigeration cycle attempts maintaining deep cryo-temperatures?
A)Decreasing coefficient of performance occurs
B)Compressor component overheating accelerates significantly✓
C)Refrigerant backflow through expansion valve
D)System ice blockage is quickly initiated
💡 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.
