Receiver dryer stores refrigerant.

The main concept is that the receiver-dryer serves as a reservoir for liquid refrigerant in the system. Placed in the liquid line, its primary job is to store liquid refrigerant so there’s a steady supply to the metering device and to act as a buffer during varying operating conditions. It also contains desiccant to absorb moisture and a filter to trap debris, protecting the refrigerant and preventing contaminants from circulating. While moisture removal and filtration are important auxiliary roles, the essential purpose is to provide a stored quantity of liquid refrigerant. Condensation of vapor happens in the condenser, not in the receiver-dryer, which is why storing refrigerant is the best description of its function.
