What is the primary purpose of the A/C system's accumulator?

The primary purpose of the A/C system's accumulator is to separate liquid and vapor refrigerant. The accumulator is typically located in the refrigerant line between the evaporator and the compressor. Its main function is to ensure that only vapor refrigerant enters the compressor, as liquid refrigerant can cause damage to the compressor. When refrigerant flows through the accumulator, it allows any remaining liquid refrigerant to evaporate, thus preventing liquid from entering the compressor and ensuring that the system operates smoothly and efficiently.

While other components of the A/C system may be responsible for filtering debris or enhancing efficiency, the specific role of the accumulator is to manage the state of the refrigerant and safeguard the compressor. The separation of liquid and vapor refrigerant is crucial in maintaining the overall integrity and longevity of the A/C system.
