Process Simulation of Energy Behaviour of Pneumatic Drives

In this article the energy analysis of the pneumatic system is implemented in the simulation model. Previous research has shown the comparison of methods for the investigation on the energetic behaviour of pneumatic drives and its practical application. Concerning the analysis of the methods for determination the energy efficiency, the presented model is based on exergy analysis. Exergy analysis is able to consider all energy losses as well as the influence of the temperature behaviour on the available useful pneumatic energy.Factors concerning the energy efficiency are discussed and described upon the thermodynamical processes at pneumatic drive.The paper represents the exergy model of each type of pneumatic components, e.g., pipe, pneumatic resistor and actuator. Each component differs through the determination of energy losses. The preliminary simulation analysis provides the information of the efficiency of certain component and offers the optimization of the system through the validation of system parameters.
