“…Energy losses in CAS occur during compression, transmission due to leaks [5] and the utilisation stage through excessive air consumption [6]. Methods to improve efficiency in compressors and air leaks are well described in the literature and technology [7][8][9]. However, methods for reducing compressed air consumption are less well presented and can achieve an increase in energy efficiency by up to 40%.…”

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.

“…Soylu et al [20] conducted a comprehensive study to assess the energy-saving potential of rectifying air leakages in pneumatic systems, thus revealing a substantial 42% reduction in energy costs using an ultrasonic flow meter. Doner and Ciddi [21] investigated various energy-saving strategies, including leakage elimination, compressor operation optimisation, and waste heat recovery methods. They established significant correlations between the system parameters, thereby providing valuable insights for more efficient CASs in industrial applications.…”

Pneumatic machines and systems are highly popular in the automation and mechanisation of production lines in many industry sectors, such as, e.g., food, automotive, production, and packaging. However, the energy efficiency of the pneumatic system is very low at about 10 to 20% The exhaust air from pneumatic machines has high energy, which is considered waste. This study introduces a novel energy recovery machine designed for integration into industrial compressed air systems. The authors describe the potential of the recovery machine within an industrial environment and present a developed exhaust air recovery system which collects exhaust air and converts it into electricity. Comprehensive industrial tests were conducted to evaluate its performance. The results, along with a detailed analysis, are presented, thereby showing there machine’s capabilities in recovering energy from compressed air processes. This research provides valuable insights into the practical implementation and benefits of deploying such energy recovery systems at an industrial scale. The findings demonstrate the machine’s potential to enhance energy efficiency and reduce operational costs in a wide array of industrial applications that are reliant on compressed air.
