[Equest-users] Properly modeling PTAC and Baseboard system

[Alex Krickx]

Bill- I did do that, thanks for checking.

Paul- The building engineer hasn't said there was any separate ventilation system so I assumed that the through wall AC would take care of the ventilation.  Does the eQUEST PTAC system not include ventilation?

Thanks for your help!

Alex,
You have not said if or how you are ventilating these spaces.

Alex,
Sounds good so far. Make sure you select "System per Zone" for the PTAC system.

Hi everyone,

I have a (hopefully simple) question on how to model a senior living center HVAC system.  Central natural gas boiler provide heating which is delivered through baseboards and cooling is provided by through-wall AC units (one per each apartment).

I've modeled the system as Cooling: DX coils; Heating: None; System Type: PTAC (no heating).  I'm currently in the DD Wizard so on Wizard Screen 6 I've selected Baseboard source as Hot Water Loop.

I'm hoping that someone can confirm this is the correct way to model this system.

Thanks very much.

Regards,
Alex Krickx
