Dear eQuest users,<br>
I've been trying to model a DOAS that supplies ventilation air to the
other HVAC systems.<br>
In order to keep the ECO & ERV capabilities, I use PSZ for the DOAS.<br>
After quiete a long time of messing arround with the different options
I could imagine, I came along a solution that seems to more or less
match the expected results. However the cooling & heating
consumptions are a bit lower than what should be (comparison case
without DOAS).<br>
The dummy zone used for the DOAS introduces no demands (LS-E report)
nor system loads (SS-A report). However, I observe in the SS-K report
that the dummy zone has a temperature slightly different than outside
temperature that could explain the differences between the calculated
and expected cooling & heating consumption (an in fact de DOAS has
a design cooling capacity different from zero in spite of my efforts to
make it null). The DOAS fans do not introduce any loads.<br>
Any insight on how to introduce the DOAS without any impact on the
calculation accuracy of heating and cooling demands?<br>
Thanks,<br>
