An accumulator is used to

  1. Adjust superheat levels

  2. Prevent liquid refrigerant from reaching the compressor

  3. Reduce noise in the system

  4. Store excess refrigerant

The correct answer is: Adjust superheat levels

An accumulator is used to prevent liquid refrigerant from reaching the compressor. This is important because if liquid refrigerant enters the compressor, it can cause damage to the compressor due to its inability to compress liquids effectively. Instead, the accumulator ensures that only vapor refrigerant enters the compressor, thus protecting it from potential damage. Adjusting superheat levels, reducing noise in the system, and storing excess refrigerant are not the primary functions of an accumulator in an air conditioning system.
