🔍 Key Concepts

• Desiccant systems remove moisture from air by absorption or adsorption, not by adding water • Difference between heating coils and cooling coils in how they affect condensation and evaporation • What happens to water vapor in humid air when it contacts a surface that is colder or hotter than the air

💭 Think About

• Think about how you normally remove moisture from air in everyday systems like air conditioners or dehumidifiers: do they usually cool the air or heat it to get the water out? • When warm, humid air passes over a coil, under what temperature condition will the water vapor turn to liquid and be collected? • In a liquid desiccant system, does the desiccant solution want to pick up water from the air, or reject it back into the air, while it is in contact with that air stream?

✅ Before You Answer

• Identify whether condensation of water vapor requires a colder or hotter surface than the air • Decide whether a desiccant in the cargo-hold air stream should be in the phase of absorbing water or rejecting water at that point • Check which options confuse water (liquid) with water vapor (gas) and whether "evaporated and driven out" makes sense for a system that is supposed to dry the cargo-hold air

Question 1 of 20

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

Water from the humid air inlet from the cargo-hold is evaporated and driven out of the liquid desiccant by means of a cooling coil located in the humidification chamber.

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.

Water vapor from the humid air inlet from the cargo-hold is condensed and absorbed into the liquid desiccant by means of a heating coil located in the humidification chamber.

Water from the humid air inlet from the cargo-hold is evaporated and driven out of the liquid desiccant by means of a heating coil located in the humidification chamber.
