to estimate the energy use of building design at detail design stage
by using DOE2 energy modelling. I am trying to modify the actual
performance curve for<SPAN class=267184822-20022007> chiller</SPAN> pump,
boiler, cooling tower etc in DEO2, because w</SPAN>e <SPAN

different from the default performance curve. We hope to specify the performance
curve for each individual project. <SPAN

<DIV dir=ltr align=left><FONT color=#0000ff size=2><FONT color=#000000><FONT
size=3><FONT face=Arial>I defined the mechanical efficiency of pump is 0.75,
motor efficiency is hi-eff. I assume that the program can calculate the pump
flow based on the load, use PUMP-HEAD-FFLOW to calcualte the head, and then work
out pump power with PUMP-HP-FFLOW, using Pump default motor efficiencies chart
to figure out the ele energy use. <SPAN class=856040023-20022007><FONT
