[Equest-users] VRF system modeled as a water loop heat pump with dedicated outside air systems

[David Frank]

Cyrus,

 

In the past I've created a dummy zone with no loads and adiabatic walls and
had it as a detached separate building.  I dedicated the DOAS to this dummy
zone and had all PSZ units receive their OSA from the DOAS.  If I remember
correctly, I had to create the DOAS in the schematic wizard prior to the PSZ
units for this to work properly.

Hello all,

 

 

I'm having a problem modeling water loop heat pumps with a separate DOAS
supply. I can't get the DOAS to work! I'm trying to get model it as a PSZ
unit with furnace heat. The program says it needs a control zone to work.
The thing is, I don't want the air handler to condition any zones.  Do I
make  Dummy zone? If so, do I make a dummy space?
