Hello Friends,<br>
<br>
I am modelling an office building which is run on electricity
generated by natural gas fired generators (say, NGG). The exhaust
heat is being used to run a 2-stage absorption chiller to provide
complete space cooling for the building. However I have modeled
exhaust heat as heat recovered in a hot water loop which also had to
be supplemented by a boiler since eQUEST cannot model it without.<br>
<br>
Now the issues are:<br>
<ol>
<li>Is this a good way to model the cooling? I will appreciate any
nuances if someone can share those with me.</li>
<li>Understanding of one key utility meter report "EGen" in BEPS/
BEPU. Please check out "<font color="#3333ff">GG input.jpeg</font>".
EGen, ESrp and FInp are allocated in the NGG Input box in the
tabs electric meter, Surplus meter and Fuel meter respectively.
FM1 is attached to the hot water exhaust coming from the GG Set.
EM1 and FM2 are left default without any assignments. Another
meter "EM3" which is a sub meter to EGen utility meter is
reporting part consumption of all electricity usage in the
building, however PS-F report shows complete energy consumption
as 39XXXXX kWh units both in EGen (Utility) and EM3 (sub meter).
Now the big questions are :<br>
</li>
<ul>
<li>Is EGen and its sub meter EM3 indicating the fraction of
energy consumption from the whole or additional amount of
energy requirement for the building which NGG was unable to
provide?</li>
<li>If it is the additional energy requirement, then why is
surplus meter showing any reading?</li>
<li>Is FInp and FM1 reporting overall gas consumption by the
NGG?<br>
</li>
</ul>
</ol>
I look forward to any inputs on these issues.<br>
Thanks in advance!<br>
Sincerely,<br>
Anup
