Which statement is true concerning a liquid desiccant cargo-hold dehumidification system?
AI Explanation
The correct answer is 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.
This is correct because in a liquid desiccant cargo-hold dehumidification system, the humid air from the cargo-hold is passed over a cooling coil, causing the water vapor to condense and be absorbed into the liquid desiccant. The liquid desiccant then becomes more concentrated, and the absorbed water is later driven off by a heating coil, allowing the desiccant to be reused.
The other options are incorrect because they describe the opposite process - using a heating coil to drive water out of the desiccant, rather than a cooling coil to condense and absorb water into the desiccant.
