← TechnologyWhich outcome occurs when an HVAC evaporator coil's airflow becomes restricted by accumulated dust?
A)Compressor overheating from increased backpressure
B)Refrigerant overcharge from reduced heat absorption
C)Decreased cooling capacity from reduced evaporation✓
D)Increased energy efficiency from prolonged cycling
💡 Explanation
When airflow is reduced, diminished heat transfer reduces evaporation, leading to less refrigerant phase change because latent heat extraction is limited. Therefore decreased cooling capacity results, rather than compressor issues, overcharge, or improved efficiency which require different thermal conditions or system changes.
