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