DesignSpecification:OutdoorAir for PTAC [closed]
I am trying to use OpenStudio and EnergyPlus to model the internal sensible and latent loads for a building. EnergyPlus will output all sensible loads fairly easily, but it's a different story for internal latent loads (in my situation almost exclusively people). From hours of digging it looks like using a 'dummy zone equipment', for example a PTAC (specifically a Cycling PTAC DX Clg Elec Htg object) is the best way to get access to the latent load. It looks like I am getting some latent loads with this. Success. Since I've included infiltration into the model I'm sure that this latent load also includes infiltration. That's fine, I can take out infiltration when I need to.
However, now I'd like to add in the latent load due to outdoor air flow. I see the three objects that can control outside air, but based on this section of the Input - Output documentation I was expecting an option somewhere for the Field: Outdoor Air Method, but I cannot find it. I'd like to know how the outdoor air flow is being autosized for this zone through the PTAC. Any suggestions?
