Accumulator HVAC: Description and Operation
The accumulator is mounted in the engine compartment between the evaporator coil outlet tube and the compressor inlet.
Accumulator - Typical
Refrigerant enters the accumulator canister as a low pressure vapor through the inlet tube. Any liquid, oil-laden refrigerant falls to the bottom of the
canister, which acts as a separator. A desiccant bag is mounted inside the accumulator canister to absorb any moisture which may have entered and
become trapped within the refrigerant system.
