← ScienceWhich mechanical outcome occurs inside a refrigeration system when the condensing temperature increases significantly,?
A)Compressor overheating from high discharge pressure✓
B)Evaporator frost buildup decreasing efficiency
C)Expansion valve corrosion accelerating refrigerant leaks
D)Condenser coil cracks due to thermal stress
💡 Explanation
When condensing temperature rises, compression ratio increases because the compressor must work harder to achieve required high-side pressure causing excess motor current leading to overheating. Therefore, compressor overheating results, rather than frost, valve corrosion, or coil stress, which depend on other faults.
