Has anyone modeled a dual-path unit such as those often found on the roof of a supermarket? Is there an item in the library or BCL, or does it need to be built from its component parts?

Thanks, Dan

I'm sorry I'm not familiar with this system. Can you describe it in a little more detail? Considering that nobody has answered yet maybe other people are equally unsure. If you provide some details I'm pretty sure we can outline what is possible with OS / EnergyPlus.

Tha Hi Kyle,

Sure, I can describe it. It is an air handler with two pathways, one which is used strictly for dehumidification. When a temperature or humidity condition is reached (as controlled by a set point), Outside Air (OA) will be directed over a dehumidification coil before being mixed with the Return Air (RA). After mixing, all air passes over cooling and heating coils, which are called as necessary to meet the temperature conditions. When the extra dehumidification is not required, the OA mixes directly with the RA and is cooled / heated as necessary. Thanks for your interest! Dan

Hi Dan,

IES VE can model these systems - I just completed one in Miami. It's fairly straightforward in the VE.

I don't know about E+ requirements - but there are other tools out there that can model this system type.

Kind regards,

Nathan

@nkegel, please limit VE responses to the VE mailing list and support forum. ;P

@Amir Roth is there a reason we're excluding IES VE questions from UnmetHours?
