Accumulator HVAC: Description and Operation
The suction accumulator/drier is mounted on the right side of the bulkhead. The inlet tube of the suction accumulator/drier attaches directly to the A/C
evaporator core outlet tube.
Refrigerant enters the suction accumulator/drier and the heavier, oil-laden refrigerant falls to the bottom of the suction accumulator/drier canister. A
small oil bleed hole is located in the side of the outlet tube near the bottom of the suction accumulator/drier canister. The bleed hole is covered with a
filter and allows a small amount of the heavier liquid refrigerant and oil mixture to enter the suction line at a controlled rate. When the heavier liquid
refrigerant and oil mixture enters the suction line, 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 canister is used to attach the A/C cycling switch. A Schrader valve prevents refrigerant loss
when the A/C cycling switch is removed.
