Receiver dryer absorbs moisture.

Receiver dryer absorbs moisture.

• A. Stores refrigerant
• B. Absorbs moisture
• C. Condenses vapour remaining in refrigerant
• D. Filters refrigerant

Answer: (B)

Moisture in the refrigerant is harmful, so the receiver-drier uses desiccant material to absorb water as the refrigerant flows through. This moisture removal prevents issues like acid formation with the lubricating oil, corrosion, and ice formation in the metering device, all of which can degrade performance or cause failures. While the unit can also help filter out small particles and provides liquid refrigerant storage, its primary job is to remove moisture from the system.
