1 : 020 8399 7151 Edinburgh: 0131 659 5333 SUCTION line ACCUMULATORSVIRGINIA KMP SUCTION line ACCUMULATORSC ompressors are designed to compress vapours, not liquids. Many systems, especially at low temperatures, are subject to the return of excessive quantities of liquid refrigerant, which dilutes the oil, washes out bearings, and in some cases leads to complete loss of oil in the crank case. This results in broken reed valves, pistons, rods, crankshafts, etc. The purpose of the accumulator is to act as a reservoir to temporarily hold the excessive refrigerant-oil mixture and to return it at a rate which the compressor can safely handle. Should be sized to hold 50% or more of total system RESEARCH SUCTION line ACCUMULATORSSELECTION OF SUCTION ACCUMULATOR The SUCTION accumulator should not necessarily be selected to have the same size inlet and outlet as the compressor SUCTION line .

2 It is more important to select the SUCTION accumulator well within the limits of (1) pressure drop, (2) oil return and (3) total amount of charge to be HOLDINGCAPACITY (R22 4 C)CONNECTIONSLIST MODELCODETOTALHEIGHTDIAMETERMAXIMUM HOLDINGCAPACITY (R22)CONNECTIONSLIST MODELCODETOTALHEIGHTCOPPER SPUN SUCTION line ACCUMULATORSDIAMETERCONNECTIONSLIST MODELCODELENGTH0112700112710112720112730 11274011275VA32-5 SVA32-6 SVA54-7 SRDVA57-9 SRDVA59-11 SRDVA616-13 SRD5/8 solder3/4 solder7/8 solder1-1/8 solder1-3/8 solder1-5/8 solder2-5/8 solder3-1/8 solder1/4 solder1/4 solder5/16 solder5/16 solder5/16 solder5/16 solder3/8 solder3/8 solder3/8 solder3/8 solder3/8 solder3/8 solder3/8 solder5/16 solder5/16 : 020 8399 7151 Edinburgh.
