Table 4. Calculation Steps of Oxygen Compressor Energy Consumption.

procedure	specific operation
STEP1	use Matlab R2014a software to calculate the inlet guide vane opening k according to the intake flow Q_i and exhaust pressure P_o
STEP2	calculate the shaft power N_z from the inlet guide vane opening k and the intake airflow Q_i
STEP3	calculate the isothermal efficiency η_T combined with the isothermal efficiency calculation formula of the CC
STEP4	use the trapz function in Matlab R2014a software to calculate the integral of the shaft power N_z during the study period to obtain the value of the total energy consumption E_co
