Refrigeration & Air Conditioning USCG Question #602 (Set 12)

With regard to the cooling and heating coils and humidification and regeneration chambers of a liquid cargo-hold dehumidification system, what statement is true?

Official USCG Answer & Rule Citation

Correct Answer: Option C — The chamber that processes the cargo-hold air contains the cooling coil and is known as the humidification chamber. The chamber that processes the outside air contains the heating coil and is known as the regeneration chamber.

Cargo air passes through the humidification chamber containing a cooling coil to absorb moisture, while outside air passes through the regeneration chamber containing a heating coil to drive moisture out of the desiccant, completing the continuous marine dehumidification cycle.
