Case 1: Energy-Saving Solution with Inverter Compressors
Previously, only constant-speed compressors were used. However, because the required compressed air volume fluctuated significantly depending on the number of operating units, inverter compressors were selected for their energy-saving potential based on real-time operating conditions. Line pressure control was implemented on the inverter compressors, enabling operation at optimal pressure settings near the usage points at all times, resulting in a pressure reduction of approximately 1.5 bar. Additionally, by utilizing the group control function, the entire system achieved around 13% energy savings (approximately 120,000 kWh annually).
