DOAS for Dehumidification Paired with RTU for Heating/Cooling
The system I'm trying to model in OpenStudio is a DOAS unit with an enthalpy wheel and DX coil doing only dehumidification, and then sending dehumidified air to a regular rooftop unit for additional heating/cooling. I've represented the setup I'd like to use here but haven't been able to get it to run. The run just crashed without a proper error report so I can't get an indication of the actual issue. Has anyone had success modeling this type of system before? Thanks!
I can only speak to this topic as a designbuilder user. DB does not allow airloop to airloop connection. Further, DB does not allow multiple ADUs within a zone group. Thus, when we design an ERV to connect to the return of an RTU, I have to model the ERV functionality within the RTU.
