What is the main purpose of a suction line accumulator?

• A. To maintain the pressure in the system
• B. To recover liquid refrigerant during operation
• C. To prevent liquid from entering the compressor
• D. To ensure consistent airflow in the duct system

Answer: (C)

The main purpose of a suction line accumulator is to prevent liquid refrigerant from entering the compressor. In a refrigeration or air conditioning system, the compressor is designed to compress vapor rather than liquid. If liquid refrigerant enters the compressor, it can cause damage due to the inability of the compressor to compress liquid. The accumulator functions by collecting any liquid refrigerant that may have made its way down the suction line before reaching the compressor. It allows only vapor to pass through to the compressor, ensuring safe and efficient operation of the system. This role is critical in maintaining the integrity of the compressor and the overall efficiency of the refrigeration system, as it helps prevent potential issues such as hydraulic shock and compressor failure.
