Accumulator HVAC: Description and Operation
SUCTION ACCUMULATOR/DRIER
The suction accumulator/drier is mounted on the right side of the dash panel. The inlet tube of the suction accumulator/drier attaches directly to the
evaporator core outlet tube.
Refrigerant enters the suction accumulator/drier and the heavier, oil-laden refrigerant falls to the bottom. A small oil bleed hole is located in the
side of the outlet tube. The bleed hole is covered with a filter and allows a small amount of the heavier liquid refrigerant and oil mixture to enter
the A/C compressor suction manifold and tube at a controlled rate.
When the heavier liquid refrigerant and oil mixture enters the A/C compressor suction manifold and tube, it has a second opportunity to vaporize
and circulate through the A/C compressor without causing damage.
A desiccant bag is mounted inside the suction accumulator/drier to absorb any moisture in the refrigerant system.
A fitting located on the top of the suction accumulator/drier is used to attach the A/C cyclic switch. A Schrader valve stem prevents refrigerant loss
when the A/C cyclic switch is removed.
