Accumulator HVAC: Description and Operation
Accumulator
The accumulator is mounted in the engine compartment between the evaporator coil outlet tube and the compressor inlet. Refrigerant enters the
accumulator canister as a low pressure vapor through the inlet tube.
Accumulator - Typical
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.
