← TechnologyWhich consequence results when ice forms non-uniformly on an evaporator?
A)Compressor motor overheating occurs faster✓
B)Refrigerant subcooling increases noticeably
C)Volumetric efficiency increases sharply
D)Ozone depletion potential decreases slightly
💡 Explanation
Ice restricts airflow; therefore, the evaporator's heat exchange reduces. This reduced cooling increases the temperature of the returning refrigerant vapor, raising the compressor's discharge temperature because the "vapor compression cycle" works less efficiently, therefore leading to the compressor overheating rather than operating normally.
