We had chiller unit to chill the water to provide 4 degC for Oil Fractionation system.
The chiller consist of two circuits, where one circuit has three compressors and the other has two compressors. The compressors are come from Carlyle Compr. 06EA599600 (it was 06EA299600 before).
Yes the compressors were installed in parallel system. However preventing process shutdown due to repetitive failure of the compressors, we now try to make a compressor work as individual as possible, by installing each compressor with individual oil separator and controls. However we still (due to evaps and condenser) we still at the end paralleling those such as after oil separators has a discharge manifold to condensor and having one suction accumulator at each circuit before entering compressors. Compressors are started in asequence according to the temperature ranging from 8 degC down to 4 degC. Our recent problem now is the oil migrate not from "run" unit to "off" unit, but rather from "off"(?) to "run" unit. In circuit having three compressors, the oil flooded was found in the middle one. We are not using the equalizing line as recommended due to the fact that preventing liquid flooded and shutdown the whole process just to rework on the compressor. That process is our company's backbone product.
We need anybody advice to levelling the oil at the compressor, working in semi-parallel like we had. We need the answer urgently.
Thanks
