Claim 0:
1. A method for analyzing energy used for producing a unit of mass or volume of compressed gas (Specific Energy Consumption) in relation to a common output flow in a compressor system, said method comprising the following steps:
for time interval, Tref, collecting reference measured data points of common output flow Fref and energy (or power) consumption Eref (or Pref) in the compressor system;
calculating energy (or power) use as a function of the common output flow Eref (F) (or <Pref>t(F)) from the measured data points and calculating volume output as a function of the common output flow Vref(F);
calculating average energy consumed for producing a unit of mass or volume of compressed gas as a function of the common output flow

<SECref>t(F) from equation Eref(F)/Vref(F) (or <Pref>t(F)/Fref);

for time interval, Tsav, collecting measured data points of common output flow Fsav and energy (or power) consumption Es (Ps) in the compressor system;
calculating energy consumed for producing a unit of mass or volume of compressed gas as a function of the common output flow <SECsav>t(F) from equation

Esav(F)/Vsav(F) (or <Psav>t(F)/Fsav) or SECsav(t,F) from Psav/Fsav,

calculating the difference between <SECref>t(F) and <SECs>t(F) or SECsav(t,F) over a range of common output flow F in the compressor system.
