Refrigeration Frequency inverter control
Dear All,
Can somebody tell me where can i download some literature where it is explained the technology of working refrigeration system with example: 3 compressors, one is with frequency inverter, other direct with contactor, 6fans, PLC, 2 pressure sensors 4-20mA(LP and HP), temperature sensors(room and outside), etc.
It is for freezing meat for example.
There is one controller Eliwell EWCM9100 witch we would like to replace.
PLS if somebody can send me the link or by email the litterature explaining the ligic and control theory so we could write the program in PLC?
Any help is hugely appreciated!
Best Regards
Stanislas
