Hello,
For the baseline case of LEED, I have to model a primary pump for each chiller and one secondary pump for the chiller system (ASHRAE 90.1-2007: G3.1.3.11).
I've exported my model from DesignBuilder(DB) to Energy Plus, but in DB I just can set one primary and secondary pump for the chiller system (not for each chiller).
The secondary pump is ok (just one for the system, not for each chiller), however I need to set one primary pump per chiller, as stated in G3.1.3.11. How can I add an aditional primary pump for the other chiller?
I think that combining primary pumps in series might be right, however if I do that, LEED reviewers would check that the number of primary pumps doesn't match with the number of chillers.
Please advice.
Thanks in advance.
-Billy.
