Hi All,
I have some questions about modeling VFD pumps in a closed loop is it the only way to model VFD pumps by putting the values for Speed vs efficiency curve as below figure? and if so let say if i enter 8 points this means that we define 8 characteristic curves for the one VFD pump?
and for the BEP flow and BEP efficiency if i have 8 characteristic curves this means i should add BEP for each one or just for pump at full speed ?
and the same for the curve Multi points flow Vs Head what points exactly to enter ?? i have max allowable flow, Min allowable flow and duty , should i enter all of them at full speed or for the 8 curves?
what data should be enter for the VFD pumps to run the software without any issues ??
Also note that there is a difference between the variable speed option for defining the efficiency, and modeling a pump whose speed changes (scaling the pump curve up and down). See: "Is variable speed drive?" vs "Is variable speed pump?"
