SUCTION LINE ACCUMULATORS
SA Series, Vertical, UL
The main purpose of a Suction Line Accumulator is to prevent a
sudden surge of liquid refrigerant or oil form returning down the
suction line and into a compressor. The suction line accumulator is
a temporary reservoir for liquid refrigerant and oil.
The accumulator is designed to meter both the liquid refrigerant and oil
back to the compressor at a controlled rate. This prevents compressor
damage. By metering the liquid refrigerant and oil back to the
compressor, the accumulator also helps maintain system efficiency and
proper crankcase oil levels.
Suction Line Accumulators are installed in air conditioning and refrigeration
systems where a sudden return of liquid down the suction line is possible.
Henry Technologies' SA Series Suction Line Accumulators are suitable for
use with HFC and HCFC refrigerants and their associated oils, as well as
other industrial fluids non-corrosive to steel and copper.
Materials of Construction
The shell and end caps are made from carbon steel. Branch connections
are made from copper.

How it Works
Refrigerant vapor from the evaporator enters the Suction Line Accumulator,
along with any liquid refrigerant and oil. The liquid is held at the bottom of
the Accumulator until it is metered back to the compressor. A U-Tube is
connected to the outlet of the Accumulator to ensure vapor is returned to the
compressor. On Vertical Accumulators, liquid is metered back to the
compressor via a screened orifice at the bottom of the U-Tube. This
metering only occurs when the compressor is running.
