Question 212General Subjects - 1st Asst/Chief

The correct answer is B) Both systems require a continuous source of heat to drive the moisture out of the desiccant. This is correct because both liquid-desiccant and solid-desiccant cargo-hold dehumidification systems utilize desiccants to absorb moisture from the air. To regenerate the desiccant and remove the absorbed moisture, these systems require a continuous source of heat to drive the moisture out of the desiccant material. The other options are incorrect because they do not accurately describe the common feature of both liquid-desiccant and solid-desiccant systems. Option A is incorrect as cooling water is not required to drive the moisture out of the desiccant. Options C and D are incorrect as these systems use heat, not cooling water, to absorb moisture into the desiccant.
