AB - Reciprocating-piston compressors and expanders arepromising solutions to achieve higher overall efficiencies invarious energy storage solutions. This article presents anexperimental study of the exergetic losses in a gas spring. Consideringa valveless piston-cylinder system allows us to focuson the thermodynamic losses due to thermal-energy exchangeprocesses in reciprocating components. To differentiate this latterloss mechanism from mass leakages or frictional dissipation,three bulk parameters are measured. Pressure and volume arerespectively measured with a pressure transducer and a rotarysensor. The gas temperature is estimated by measuring theTime-Of-Flight (TOF) of an ultrasonic pulse signal across thegas chamber. This technique has the advantage of being fast andnon-invasive. The measurement of three bulk parameters allowsus to calculate the work as well as the heat losses throughouta cycle. The thermodynamic loss is also measured for differentrotational speeds. The results are in good agreement withprevious experimental studies and can be employed to validateCFD or analytical studies currently under development
