Suction line accumulators protect the motor from slugging of which component

• A. Condenser
• B. Evaporator
• C. Fan
• D. Compressor

Answer: (D)

The suction line accumulator is there to prevent liquid refrigerant from reaching the compressor. Slugging happens when liquid refrigerant is drawn into the compressor, causing hydraulic shocks, poor lubrication, and excessive motor load. The accumulator traps and vaporizes that liquid so only vapor enters the compressor, protecting the motor from damage. The condenser, evaporator, and fan aren’t the components whose slugging would harm the motor in this way, so preventing liquid from entering the compressor is the key purpose.
