Refrigeration & Air Conditioning USCG Question #142 (Set 3)

If a condenser coil of an air-cooled container refrigeration system becomes dirty and requires cleaning, what would be an acceptable method of cleaning?

Official USCG Answer & Rule Citation

Correct Answer: Option C — high-pressure water wash

High-pressure water washing safely dislodges accumulated salt, dust, and lint from air-cooled condenser fins without bending delicate aluminum heat transfer surfaces or damaging the tubing, maintaining optimal marine refrigeration heat rejection efficiency.
