An accumulator serves a crucial function in refrigeration and air conditioning systems by keeping liquid refrigerant out of the compressor. When the refrigerant flows through the system, especially during low load conditions, it can become problematic if liquid forms and makes its way into the compressor. Compressors are designed to compress gas, and the presence of liquid refrigerant can cause damage or failure.

The accumulator collects any excess liquid refrigerant that might come from the evaporator, allowing only the vaporized refrigerant to continue into the compressor. This process not only protects the compressor but also helps to ensure the overall efficiency and longevity of the refrigeration system. By allowing for the separation of vapor and liquid, the accumulator plays a vital role in maintaining the proper operation of the entire system, highlighting its important function beyond merely being a storage device or pressure regulator.
