October 1, 2012

There are times when low evaporator heat loads, just ended defrost periods, failing or misadjusted mechanical valves, or simply lack of system maintenance can cause compressor floodback. If there is no way to prevent these periods of liquid floodback to the compressor, a suction line accumulator is needed on the system.
