Re: [EnergyPlus_Support] Boiler pump control





Would the Pump being Intermittent vs. Continuous make any difference?

I should know this? but I don?t.

·         I have defined a simple boiler plant loop as shown below

·         Boiler 1 is defined to operate first, then both Boilers, based on their load capacity

·         From the CSV report variables, the boilers appear to be operating as I intend:

o   Boiler 1 is operating (indicated by raising the temp of incoming water)

o   Boiler 2 is NOT  operating (indicated by temp of incoming water remaining unchanged)

·         BOTH boiler branches have flow, but I want flow only when the boiler is active

·         For the Boiler Branches, I defined:

o   the Pumps as ?passive? and boilers as ?active? for both branches (both branches have flow)

o   And then switched pumps to ?active?, boilers to ?passive? (same results)

o   And then reviewed the IO Reference and found that they?re not supposed to affect the simulation at all.

 

How can I stop flow when the boiler is inactive?

Thanks in advance!

Making me think?.

Seek truth while you are young, for if you do not, it will later escape your grasp
