G.Zick

LPL compressors fully loaded in all modes:

- Mode 2: Recirculation between LPR and LPL and 50g/s between MP to LPL

- Modes 3 to 7: Recirculation between MP and LPL only

Control of LPL stage with no VFD nor Slide Valve, extra flow is by

G.Zick - Mode 6 updated

- Mode 8 added ("50% Standby")

Mode 6 : T1 and T3 efficienciesadjusted ; Carnot efficiency calculation taking into account all the compressors fully loaded

Mode 8

JUSTIFICATION OF THE MODIFICATION

Control of LPL stage with no VFD nor Slide Valve, extra flow is by-passed.

ode 6 : T1 and T3 efficiencies adjusted ; Carnot efficiency calculation taking into account all the compressors fully loaded
