ACCUMULATOR TANK CONSTRUCTION

BUE071161500N01

• The accumulator tank is mounted to the accumulator tank bracket. The inlet tube of the accumulator tank is connected to the evaporator outlet tube. The outlet tube is connected to the refrigerant line.

• After entering the inlet of the accumulator tank, heavier oil-laden refrigerant contacts an internally mounted dome (which serves as an umbrella) and drips down onto the bottom of the canister.

• A small diameter oil bleed hole, in the bottom of the vapor return tube, allows the accumulated heavier liquid refrigerant and oil mixture to re-enter the compressor suction line at a controlled rate.

• As the heavier mixture passes through the small diameter liquid bleed hole, it has a second chance to vaporize and recirculate through the A/C compressor without causing compressor damage due to slugging.

• A fine mesh screened filter fits tightly around the bottom of the vapor return tube to filter out refrigerant system contaminant particles.

• A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system.

• A fitting located on the top of the accumulator tank is used to attach the A/C cycling switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C cycling switch can be removed without discharging the A/C system.
