Abstract
Pneumatic systems are widely used to automate production lines in manufactured plants. Their big disadvantage is their low energy efficiency, 10-20%. It is mainly due to the overconsumption of compressed air by the oversized pneumatic actuator and other components. Reducing air consumption at the utilisation stage can result in significant exergy savings. This can be done by lowering the supply pressure, introducing back pressure, or using expansion energy in the actuator. The most promising is the last method that can be implemented using the intermittent air supply in the pneumatic actuator. The literature lacks an exergy analysis of the utilisation stage of pneumatic and intermittent air supply systems. There is also no optimisation of the control algorithm of intermittent air supply control algorithm in terms of minimising exergy consumption. In this paper, we demonstrate a mathematical model and exergy analysis as a tool for assessing the efficiency of the utilisation of pneumatic system and conduct computer simulation. Exergy analysis showed that for intermittent air supply the reduction in exergy consumption decreased by more than 60% compared to the classic oversized system. The results of the computer simulation give the opportunity to optimise the operation of the utilisation stage in pneumatic systems. Furthermore, exergy analysis can be a useful tool for energy analysis and assessment of pneumatic systems, as well as providing information on the desired direction of changes in the installation.
