Abstract: Pneumatic systems are widely used in industrial production. It is valuable to conduct detailed analyses on pneumatic systems in the interest of improving their energy performance. In this study, an exergy-based efficiency analysis framework is proposed for industrial pneumatic systems. The product exergy, fuel exergy, and exergy efficiency of various pneumatic components are clearly defined. The exergy sensors and exergy analysis toolbox are developed in the software AMESim. Finally, both simulation and experiment of a typical pneumatic system are conducted and compared to validate the feasibility of the proposed exergy-based efficiency analysis framework.

Keywords: pneumatic; exergy; energy saving; exergy efficiency; compressed air.
