The A/C gas receiver (or receiver-drier) is a storage tank. Located on the high-pressure side of the system, it acts as a reservoir for liquid refrigerant exiting the condenser. It contains a desiccant material to absorb moisture and a filter to catch debris. It ensures that only clean, moisture-free liquid refrigerant reaches the expansion valve.
