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
contamination from a failed A/C compressor or damage to the suction accumulator.
After entering the inlet of the suction accumulator, heavier oil-laden refrigerant contacts an internally mounted dome (which serves as an umbrella) and
drips down onto the bottom of the canister.
-
A small diameter oil bleed hole, in the bottom of the vapor return tube, allows the accumulated heavier liquid refrigerant and oil mixture to
re-enter the compressor suction line at a controlled rate.
-
As the heavier mixture passes through the small diameter liquid bleed hole, it has a second chance to vaporize and recirculate through the A/C
compressor without causing compressor damage due to slugging.
-
A fine mesh screened filter fits tightly around the bottom of the vapor return tube to filter out refrigerant system contaminant particles.
-
A desiccant bag is mounted inside the canister to absorb any moisture which may be in the refrigerant system.
-
A fitting located on the side of the suction accumulator is used to mount a serviceable low-pressure A/C charge port valve.
