Applications requiring intermittent operation of the refrigeration compressor may trap or hold quantities of liquid in the suction line which are suddenly dumped into the compressor as it starts up. Proper installation of the suction accumulator, just before the compressor, eliminates damage. Liquid is temporarily held in the suction accumulator and metered back to the compressor along with any oil, at a controlled rate, through the metering orifice.
