Question 214General Subjects - 1st Asst/Chief

The correct answer is C. The chamber that processes the cargo-hold air contains the cooling coil and is known as the humidification chamber. This is because the purpose of the humidification chamber is to remove moisture from the air in the cargo hold, which requires cooling the air to condense the water vapor. The chamber that processes the outside air contains the heating coil and is known as the regeneration chamber. This is because the regeneration chamber heats the outside air to evaporate the moisture that was removed from the cargo-hold air in the humidification chamber, allowing the system to continuously remove humidity from the cargo hold. The other answer choices incorrectly describe the function and components of the humidification and regeneration chambers.
