Task:

Implementation of a coolant moderating system at ten machine tools

• Integration of a temperature regulation system in three coolant plants
• Coolant: oil
• Power requirement for each plant - 100 kW
• Room temperature (machine tool building) closed-loop control
• Air-conditioned installation room (technical control center)

Design:

• Split-design refrigeration system
• Refrigeration set for each plant with 100 kW reciprocating piston compressor
• R134a refrigerant, free of CFCs
• Tube-sheet evaporator that can be cleaned
• Air-cooled finned liquifier with speed-controlled fans on the roof of the technical control center
• Open- and closed-loop control by the PLC system for the overall plant, fault analysis and remote maintenance by means of modem

Results:

• Uniform coolant temperature regulation directly related to ambient temparature conditions with variable parameter settings
• Low noise emissions thanks to the use of controlled fans
• Environmentally friendly design thanks to the use of refrigerants free of CFCs
• No additional thermal input into the air-conditioned technical control center
