What common feature is found on both liquid-desiccant and solid-desiccant cargo- hold dehumidification systems?
AI Explanation
The correct answer is C) 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 rely on a cyclic process of absorbing moisture into the desiccant, then driving that moisture out through the application of heat. The desiccant material, whether liquid or solid, must be periodically regenerated by heating it to expel the absorbed moisture, allowing the system to continue functioning. This heat source is a common feature shared by both types of desiccant dehumidification systems.
The other answer choices are incorrect because they do not accurately describe a common feature of both liquid-desiccant and solid-desiccant systems. Neither system requires a continuous source of cooling water to absorb moisture, nor do they require a continuous source of cooling water to drive the moisture out of the desiccant.
