Line Accumulators
The refrigeration compressor is designed to compress vapor only. A suction line accumulator prevents compressor damage from a sudden surge of liquid refrigerant and oil which could enter the compressor from the suction line. The suction line accumulator is a temporary reservoir for this mixture, designed to meter both the liquid refrigerant and oil back to the compressor at an acceptable rate. This prevents damage to the reed valves, pistons, rods, and crank shafts. Accumulators range in size from 4" to 123⁄4"in
diameter. All vessels over 6" inside diameter are designed and manufactured in accordance with Section Vlll of the ASME Code and are marked with the U or UM Code symbol. Accumulators 6" outside diameter and under are copper brazed or welded, UL listed, and equipped with copper or copper plated fittings. All our accumulators feature
a rust resistant finish which meets a 500 hour salt spray test. This is important to suction line accumulators, where moisture and condensation can result in excessive
corrosion. Accumulators have a metering ejector device that picks up liquid, vaporizes it, and returns it to the compressor.
This prevents liquid slugging and controls oil return. Vertical accumulators protect the return orifice with a screen assembly, and also feature a fusible relief device in the S-7000 Series.
