Receiver dryer filters refrigerant.

In a refrigerant system, the receiver-drier is there to clean and dry the liquid refrigerant before it reaches the expansion device. It indeed holds liquid refrigerant, but its defining role is to remove contaminants and moisture so the metering device and other downstream components aren’t damaged or blocked. The phrase that best matches this primary function is that it filters refrigerant, because the component houses a filter element and a desiccant that together remove debris and moisture from the flow. Absorbing moisture is part of its drying capability, but the most direct description of its function is filtering the refrigerant to protect the system. Condensing vapor is done by the condenser, not the receiver-drier.
