RE: [EnergyPlus_Support] Water To Air Heat Pump DOAS





The DOAS system uses a CoilSystem:Cooling:xxx object that provides control for DOAS supply air.  The AirLoopHVAC object needs a zone temperature for control. CoilSystem:Cooling:xxx will not accept Coil:Cooling:WaterToAirHeatPump:EquationFit as a valid coil.  Guess I have to look elsewhere�

OK. I know what that is :)

 Are you trying to insert AirLoopHVAC:UnitaryHeatPump:WaterToAir?

or ZoneHVAC:etc........

The ZoneHVAC version won't work in an air loop because it's a zone object.  the AirLoopHVAC object should work, however.

Ned,

What is a WAHP?  I'm not familiar with that abbreviation.

I’ve been building a complex WAHP system for a proposed building.  The design includes a WAHP DOAS ventilation air.  I used a template to build the base system, but the resulting DOAS system can only use water or DX coils.  I tried inserting a WAHP coil, but it is an invalid air loop component.  I can probably piece together an EMS solution, but I thought I would ask if anyone has implemented a more direct solution to a common issue.
