How can we measure the efficiency of pneumatic systems?
A more fundamental approach to analysing the efficiency of pneumatic systems is to examine the work producing potential or exergy of compressed air . The exergy represents the amount of useful energy, which can theoretically be converted to mechanical work .
Are pneumatic systems energy efficient?
However, a major criticism of such systems is their low energy efficiency . Since compressed air generation accounts for 10% of industrial electrical energy usage in EU , the energy efficiency of pneumatic systems is therefore an important consideration in the development of more sustainable manufacturing processes.
What is the energy usage of industrial pneumatic systems?
Energy usage of industrial pneumatic systems can be considered from two different viewpoints: electrical energy usage in the generation and treatment of compressed air and its consumption by end-user devices .
What is expansion power in pneumatic actuation?
Expansion power is the work ability of air expansion. Pneumatic actuation systems are typically considered less energy efficient than their equivalent electric counterparts. However, this is not always the case, as actual conversion efficiency is a function of actuation conditions .
