[Equest-users] HVAC system definition

Further to that last point, I've often defined relatively narrow perimeter zones specifically to account for perimeter baseboard heaters.  If you pursue this 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.

Best regards,

Dobry Den Frantisek,

Nazdar z Kanady! Na co používáte eQUEST v České republice? Budu pokračovat v angličtině...

For items 1 & 3, one of the HVAC systems available is fan-coil. This will allow for both a central AHU with your pre-heat and pre-cool. In wizard mode, you can select 4-pipe fan coil by setting the cooling source to chilled water coils and heating source to hot water coils (and can tweak this later in detailed mode if necessary).

For the baseboards, you can turn on baseboards for zone heating in wizard HVAC screen 6, though I don't think these account for the fan energy.

Another option would be to split up your zone and select unit heaters for those areas (e.g. stairwells, vestibules) if you can split it up like that.

Regards,
John

Hi,

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:

1) Central AHU with preheat/precooling chamber of outdoor air
2) Local baseboards for secondary heating (only circulation of indoor air)
3) FC units for secondary (only circulation of indoor air)

All these are for 1 zone. My question is - how to model this as equest allows only 1 HVAC system per zone?

Thanks for advice.

Frantisek
