The energy consumption factor that influences the air compressor machine is more, like centrifugal air compressor's energy consumption principle as follows:
W=ρVkR’Tln(P2/P1)/3600ηTηM
■ rho is the air density under standard state 1.293kg/m3
■ Vk is the displacement of the air compressor, m3H, R' gas constant 0.278Kkj/(kg.k)
■ T is ambient temperature, K;
■ P2 is exhaust pressure, MPa, P1 is intake pressure, MPa
■ eta tau is the isothermal efficiency of the air compressor,
■ η M is the mechanical efficiency of the air compressor.
The air compressor machine system power saving has very important meaning, can not only reduce the energy consumption, but also can promote the compressed air quality, prolong the life of air compressor machine equipment.
