Accumulator HVAC: Description and Operation
The suction accumulator/drier is mounted on the A/C evaporator case with a bracket on the right hand side of the engine compartment. The inlet tube of
the suction accumulator/drier is connected to the A/C evaporator core outlet tube. The outlet tube of the suction accumulator/drier is connected to the
A/C manifold and tube. A desiccant bag located inside the suction accumulator/drier absorbs moisture in the system. After entering the suction
accumulator/drier, heavier oil-laden and liquid refrigerant contacts an internally mounted dome and drips down into the bottom of the suction
accumulator/drier. A small diameter oil bleed hole in the bottom of the vapor return tube allows the accumulated refrigerant and oil mixture to re-enter
the compressor suction line at a controlled rate. A fine mesh-screened filter fits tightly around the bottom of the vapor return tube to filter out
contaminants.
