← TechnologyWhich outcome results when a refrigeration system's condenser coil becomes heavily fouled with dirt and debris?
A)Reduced cooling capacity from decreased heat transfer✓
B)Increased energy efficiency from added insulation
C)Lower refrigerant pressure from increased airflow
D)Compressor failure mitigated by reduced load
💡 Explanation
When the condenser coil is fouled, reduced heat transfer occurs because the dirt acts as an insulator, preventing proper condensation of the refrigerant. Therefore, cooling capacity reduces, rather than increased efficiency, lower pressure, or mitigated compressor issues, which would require different mechanisms.
