Accumulator HVAC: Description and Operation
SUCTION ACCUMULATOR
NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system except when there is physical evidence of
system contamination from a failed A/C compressor or damage to the suction accumulator.
The suction accumulator is located at the RH rear of the engine compartment. The suction accumulator is used to prevent residual liquid refrigerant from
reaching the A/C compressor after leaving the evaporator core. The suction accumulator allows the accumulated heavier liquid refrigerant and oil
mixture to re-enter the compressor suction line at a controlled rate. A desiccant bag is mounted inside the canister to absorb any moisture which may be
in the refrigerant system.
