RESEACH ON ENERGY SAVING FOR SCREW AIR COMPRESSORS

Abstract

A compressed air system can consist of a single compressor or multiple compressors working together. Compressors can also be either fixed speed (FSD) or variable speed (VSD) drive types. The energy used for compressed air systems typically accounts for 10% to 30% of the total energy consumption of a plant [1]. Therefore, an energy-saving solution for an air compressed system contributes to a significant improvement in the energy efficiency of the entire production system.

The article proposes a relatively effective energy-saving solution that is to install inverters for fixed-speed-drive screw compressors, which are currently being used very commonly in factories.
