I have an application in a very small system, where the evaporator is located above a rotary compressor, with integral suction accumulator. The system contains a capillary tube expansion device.

I would like to change the compressor to a hermetic, refrigerator-type, which does not have a suction accumulator. My concern is how to manage potential liquid flood-back from the evaporator & droplet carryover.

I have looked into small suction line accumulators, but these are very difficult to find, at the capacity of the system under consideration. Space is also at a premium.

I'd appreciate advice & applied wisdom on how to achieve this system change in a safe manner, with maximum compressor protection afforded. Thanks so much for your help.
