[BLDG-SIM] External Loads
Thanks Jim (and
all),
Upon closer inspection I see an 'HX
Power' input on the 'Heat Recovery 2' tab, which I'm presuming to be parasitic
interlocked to HX operation. Will try plugging the runaround pump
horsepower into this box, analyze the numbers and report back with the
complete 'How to Simulate a Runaround Circuit' post.
Regards
Brandon
In a ideal situation, the model would have a separate
input for auxilary power for ERVs, which some components of eQUEST (e.g.,
chillers) have that option. However, with the ERV, I would perform a hand
calc to include all of the power that the ERV consumes including your
pumps and divide that by the CFM. There is an input for kW/CFM for
ERVs. This is the same methodology I've used for Ind/Dir Evap cooling to
consider cooling tower fan and pumping energy. For systems like these, I
think it's a good idea to calculate the kW/CFM representing the components of
your specific system. Sometimes, the defaults are not respresentative of
your actual system.
Hope that helps,
Jim
All,
How about a parasitic load
that are tied to the operation of a system -- in other words loads
that don't operate directly on the basis of a schedule. Specifically
I have heat recovery pumps that need to turn on only when the ERV is
operational, and turn off when it ERV is on standby, or of course
off.
Thanks
Brandon
Lynn,
I'm assuming by external loads that you mean parking lot
lighting, for example? If so, you would model this as a direct load to the
electrical meter. This is set up by creating a schedule, double clicking
on the electric meter, entering the energy use, and then applying the
schedule.
Hope that helps
Jim
I need to model
external loads in eQuest and see in the tutorial and the end-use splits that
they are accounted for, but I can't seem to find anything that addresses how
they are entered. I'm sure it's obvious to those who know, but it's a mystery to
me. Guidance please?
Thanks.
