The purpose of a suction accumulator is ________.

• A. To Store Refrigerant
• B. To Reduce Noise
• C. It Catches And Holds Liquid Refrigerant That Has Passed Through The Evaporator Coil So It Will Not Enter The Compressor
• D. To Cool The Refrigerant

Answer: (C)

The suction accumulator’s job is to prevent liquid refrigerant from reaching the compressor. On the way from the evaporator, some liquid can still be carried with the refrigerant vapor. The accumulator catches and holds that liquid, letting only vapor proceed to the compressor. This protects the compressor from liquid slugging, reduces the risk of damage, and helps maintain proper lubrication. It’s not meant for storing refrigerant in general, nor for reducing noise or cooling the refrigerant.
