The accumulator is placed at the evaporator outlet and is used to separate liquid refrigerant from vaporized refrigerant, as well as remove any moisture contained in the refrigerant. Refrigerant enters the accumulator as it leaves the evaporator. Any liquid refrigerant is trapped in the accumulator, while vaporized refrigerant and refrigerant oil is allowed to pass on to the compressor. A desiccant bag is placed in the accumulator to remove any moisture that may have contaminated the air conditioning system. Troubleshooting and repairing automotive A/C systems typically involves inspection of the following key A/C components.
