Pneumatic systems: 10 ways to save energy

摘要

Electric motors are the real energy hogs standing between high energy bills today and cheap energy tomorrow. According to the International Energy Agency (IEA), electric motors and drive systems (EMDS) are the largest single electricity end user, accounting for more than 40% of global electricity consumption. The agency states that 32% of EMDS used are attributed to compressors. Compressors, many of which power compressed air pneumatic systems, operate on average at only 5% to 10% efficiency, offering an enormous potential for energy saving. According to an IEA report on motor-driven energy efficiency, "huge energy-efficiency potential was found untapped in EMDS. Around 25% of EMDS electricity use could be saved cost effectively, reducing total global electricity demand by about 10%."
