What component can be added to a refrigeration system to eliminate slugging?

A suction accumulator is designed to prevent liquid refrigerant from reaching the compressor in a refrigeration system, effectively addressing the problem of slugging. Slugging occurs when liquid refrigerant enters the compressor, which is meant to handle only vapor. This can cause severe damage or failure of the compressor.

The suction accumulator serves as a reservoir for any liquid refrigerant that might be present in the suction line, allowing it to vaporize before it reaches the compressor. By doing so, the accumulator helps ensure that only vapor enters the compressor, promoting efficient operation and prolonging the life of the equipment.

The other components mentioned do not serve this specific purpose. While the expansion valve regulates the flow and pressure of refrigerant, and the drier filter helps remove moisture and contaminants from the system, neither directly addresses the issue of slugging. Compressor oil is vital for lubrication but does not influence the phase of refrigerant entering the compressor. Thus, the suction accumulator is the appropriate selection for eliminating slugging in a refrigeration system.
