An accumulator in a refrigeration system is designed to prevent liquid refrigerant from entering the compressor. The primary role of the accumulator is to ensure that only vaporized refrigerant is sent to the compressor, which is crucial for its proper functioning and longevity.

If liquid refrigerant were to enter the compressor, it could cause hydraulic issues, potentially leading to compressor damage. Compressors are designed to compress gases, and introducing liquid could lead to liquid slugging, where the liquid doesn't compress, causing mechanical failures or excessive wear.

The accumulator collects excess liquid refrigerant from the evaporator, allowing only vapor to exit. By managing the flow of refrigerant in this way, the accumulator plays a vital role in the efficiency and reliability of the refrigeration system.
