Are you sure that you are clearly distinguish between suction accumulator and liquid receiver. Also, In domestic fridges, those two are rarely seen, since domestic fridges are in general with capillary tube as expansion device, and critically charged, therefore, no need for accumulation. Usualy, I see suction accumulator on cappilary tube systems on AC rotary vane compressors, since they are directly fed to suction of compressor cylinder and housing is on high pressure side.
But, maybe I am wrong!
