Re: [EnergyPlus_Support] How to model riding pump curve in E+? [1 Attachment]



Sean,
I recommend using a variable speed pump object and curve coefficients that mimic the pump curve. I attempted to duplicate a sample ASHRAE curve in the attached spreadsheet; this may give you an idea for your own pump and situation.

Hi,


I am modelling a LEED project, and coming across an issue with modelling on "riding pump curve" for hot water pump when using ASHRAE 90.1-2007 App G (G3.1.3.5). I am quite certain the pump should be a constant speed pump but it needs to deliver variable flow by riding the pump curve. How can I really model it in EnergyPlus?


Any advice would be very much appreciated.


Sean
