Hi Khaled,

 

You define the pumps when you build your chilled water plant.  In the plant
window, select the "Distribution" tab and then under Distribution System,
there is a drop down menu with three options; (1) Primary Only, Constant
Speed, (2) Primary only, Variable Speed and (3) Primary/Secondary, Variable
Speed Secondary.  I've attached a screen shot.

Hi Hap Users,

 

I am working on a simple project with an absorber chiller and 2-pipe FCU
systems. I have a problem to understand to the calculation process of the
pump powers! I am not quite sure where in the model I can include the VFDs
on my chilled water pumps to claim saving on that.

 

Please help with that if you have an answer.

 

Best Regards,

Khaled Fouda
