The component responsible for storing refrigerant in automotive air conditioning systems is the accumulator or receiver-drier. This cylindrical container holds the refrigerant in its liquid form after it exits the condenser. It also serves to filter out moisture and debris from the refrigerant, protecting other vital components of the system.
The accumulator or receiver-drier plays a critical role in ensuring the longevity and efficiency of the air conditioning system. By removing moisture, it prevents the formation of corrosive acids that can damage the compressor and other parts. Its filtering action helps maintain the purity of the refrigerant, optimizing cooling performance. Historically, these components have evolved in design and materials to accommodate different refrigerant types and system pressures, reflecting advancements in automotive air conditioning technology.
