[Equest-users] Steam loop pumping energy

[Aulbach, John]

Try setting the pump kW itself to 0, or at least 0.0001 if 0 doesn't
work.

Subject: [Equest-users] Steam loop pumping energy



All,

 

I'm modeling a university campus building with heat provided by central
plant steam boilers, providing 15# steam.  I've done this by eliminating
boilers in the model and attaching a steam meter to the hot water loop.

 

My problem is with pumping energy.  Equest requires that a pump be
attached to the hot water loop, but the actual installation has gravity
return condensate.  How do I zero out the pumping energy?  I have set
pump head = 0, but this gives me pages of error reports.  Any other
methods?

 

Thanks,

Steven
