Two companies were faced with high costs of producing compressed air. Because of this, measurements were done to determine the energy efficiency of their systems for producing compressed air. Based on these measurements the companies decided to upgrade their compression stations with variable-speed air compressors. New efficiency measurements were performed after the upgrade.
The purpose of this final thesis is to define measures for more efficient production of compressed air, along with analyzing compressors with regular control and compressors controlled by variable-speed drives. The comparison is made on the basis of measurements. Based on the analysis of these measurements, the importance of compressor control was evaluated. In the end, specific characteristics were determined for each type of control, with these characteristics also graphically displayed.
