An accumulator in a refrigeration system prevents slugging by separating what?

In a refrigeration system, an accumulator plays a critical role in managing the flow of refrigerant, particularly in preventing slugging, which occurs when liquid refrigerant enters the compressor. This can lead to damage, as compressors are designed to handle vapor rather than liquid.

The correct answer highlights that the accumulator separates vapor and liquid refrigerant. It collects surplus liquid refrigerant from the evaporator to ensure only vapor is sent to the compressor. By doing so, the accumulator effectively stores any excess liquid while allowing the compressor to operate smoothly with the vapor, thus protecting it from potential damage caused by liquid slugging.

Understanding the function of an accumulator is essential for maintaining system efficiency and longevity. It helps in balancing the phases of refrigerant, ensuring that the compressor receives vapor and preventing any liquid refrigerant that could cause issues within the system.
