<p class="MsoNormal" style="margin-bottom:12.0pt">Hello there,<br>
<br>
i am collegue of Frantisek working on the same issue. The system that is designed by design team is AHU with heat/cool coils and then just 2-pipe FCU as a secondary cooling for offices. And baseboards/radiators for primary heating. I don't see a problem with
baseboards because we can combine them togather with 4-pipe FC, VAV etc. The problem for us is how to combine 2-pipe secondary cooling FC togather with ventilation system (AHU).
<br>
<br>
The strategy of creating narrow perimetr zone sounds interesting but i dont see a problem with baseboards at this moment.<br>
<br>
Thanks for advices a Hezký večer do Kanady,<br>

strategy, I suggest being very careful to define appropriate interior air walls with the adjacent interior spaces to aid in heat transfer, and/or else re-appropriate some of the interior loads of the core areas to the perimeter zones, to avoid erroneous unmet
heating hours from those zones.</span><o:p></o:p></p>

<br>
I am modeling standard office building in equest v3.65 and I have trouble with choosing the HVAC system type. Our designed HVAC system is following:<br>
<br>
1) Central AHU with preheat/precooling chamber of outdoor air<br>
2) Local baseboards for secondary heating (only circulation of indoor air)<br>
3) FC units for secondary (only circulation of indoor air)<br>
<br>
All these are for 1 zone. My question is - how to model this as equest allows only 1 HVAC system per zone?<br>
<br>
Thanks for advice.<br>
