What is the purpose of a Suction line Accumulator used for? A suction line accumulator is used to prevent liquid refrigerant flood back to the compressor which can damage the motor windings. Accumulators are commonly used on Heat Pumps, and low temp refrigeration systems in supermarkets and in any situation where liquid refrigerant is a concern.

Most accumulators is installed in the suction line near the compressor. It usually is a vertical container with connections welded together. There is a internal U-tube inside the accumulator with a pin hole to allow liquid refrigerant or oil back to the compressor by a siphoning action.

Signs of leaks will be notice inside the unit and you will see oil the accumulator and near the compressor. When you notice the accumulator falling apart or starting to see corrosion that is the time you want to replace it. This save the customer time, money and headaches and compressor failures.
