18. How can You Improve The Energy Efficiency of The Air Compressor?
- Design the suction and discharge piping system appropriately to reduce pressure loss and leakage.
- Adopt variable frequency drive for capacity adjustment, the energy-saving effect of variable frequency air compressors can reach up to 30% to 40%, compared with ordinary inlet throttling methods.
- Uses a direct-coupled motor drive to reduce mechanical transmission losses, and also uses an efficient permanent magnet synchronous motor.
- Utilizing microcomputer control to minimize the range of loading and unloading while reducing the pressure discharge setting, while ensuring the minimum pressure conditions for gas equipment.
- Multi-unit control, automatically selecting the necessary number of machines based on the actual air consumption, thereby avoiding the significant waste caused by unnecessary multiple machines running simultaneously.
