🔍 Key Concepts

• Dehumidification chamber vs regeneration chamber – what each one DOES to the air • Where cooling removes moisture and where heating dries out/“regenerates” the air or desiccant • Which air stream is being treated: cargo-hold air (return air) vs outside/fresh air

💭 Think About

• Think about what happens when you COOL moist air: does its ability to hold water increase or decrease, and is that what you want in a dehumidification stage? • Consider what the word regeneration suggests in air-drying systems: are you drying the cargo-hold air or restoring the drying medium using another air stream? • Match the function: which chamber should actually be doing the moisture removal from the hold air, and which chamber is mainly there to restore the drying capacity of the system?

✅ Before You Answer

• Identify which chamber is directly responsible for lowering the humidity of the cargo-hold air – that is your dehumidification chamber • Confirm in your mind: cooling coils are normally associated with condensing moisture out of air, while heating coils are used to dry or regenerate another medium or air stream • Before choosing, re-check each option’s pairing: which one correctly links cargo-hold air + cooling + dehumidification and outside air + heating + regeneration, or the reverse?
