results
Circuit 1: Water cooling for various processes
Machine Room Area – Refrigeration Production; 1,400 kW cooling capacity::
• Primary refrigerant: NH₃ (ammonia)
• NH₃ system with condensation and oil cooling via chilled water in a cooling tower
o Compressor with capacity control through variable speed drive combined with slide valve system (Mycom brand)
o Cooling tower regulation with inverter-driven fans (Baltimore brand)
o Cooling for plate heat exchangers using a flooded/gravity system
• Control system with PID-Fuzzy logic, analysing trends for maximum stability and energy efficiency
Circuit 2: Cooling of ETG (50%) at low temperature for various processes
Machine Room Area – Refrigeration Production; 200 kW cooling capacity:
• Primary refrigerant: NH₃ (ammonia)
• NH₃ system with evaporative condensation and oil cooling via thermosiphon
o Compressor with capacity control through variable speed drive combined with slide valve system (Mycom brand)
o Condenser regulation with inverter-driven fans and pump (Baltimore brand)
o Cooling for plate heat exchangers using a flooded/gravity system
• Control system with PID-Fuzzy logic, analysing trends for maximum stability and energy efficiency
