What is the function of an accumulator in a refrigeration system?

An accumulator in a refrigeration system serves the crucial function of storing excess refrigerant. This component is designed to collect refrigerant vapor from the compressor and ensure that only vaporated refrigerant returns to the compressor while preventing liquid refrigerant from entering it. By storing excess refrigerant, the accumulator helps maintain the proper refrigerant flow under varying load conditions, thereby preventing damage to the compressor and ensuring efficient operation of the refrigeration system.

While energy consumption, cooling efficiency, and filtering impurities are important aspects of a refrigeration system, they are not the primary role of the accumulator. The accumulator focuses specifically on managing the refrigerant's state and ensuring the compressor receives the right mix of vapors for optimal performance. This management is essential for the longevity and efficiency of the cooling system.
