What Is a Refrigerant Accumulator?
A refrigerant accumulator is a critical component installed on the suction line between the evaporator and the compressor. Its primary function is to prevent liquid refrigerant and oil slugging — a condition that can cause serious compressor damage. The accumulator temporarily holds excess liquid refrigerant, allowing only vapor to enter the compressor, safeguarding it during startup, defrost cycles, and fluctuating load conditions.
