General Subjects (Auxiliaries & Systems) USCG Question #970 (Set 16)

Which statement is true concerning a liquid desiccant cargo-hold dehumidification system?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Water vapor from the humid air inlet from the cargo-hold is condensed and absorbed into the liquid desiccant by means of a cooling coil located in the humidification chamber.

In a liquid desiccant system, the humidification chamber uses a cooling coil to lower the temperature of the desiccant solution. This increases the solution's ability to absorb water vapor from the incoming cargo-hold air, effectively dehumidifying the air stream through condensation and absorption into the liquid desiccant.
