OS: VRFwithDOAS failed
Hi all,
I am trying to design DOAS system to my existing VRF system in OS. I have successfully designed the VRF system (1 terminal 1 thermal zone). Would like to put 5.5 l/s/person precooled outdoor intake to the room, and found out that designing the air loop coupled with VRF in OS is not easy, I tried to use the measure in BCL "VRFwithDOAS". My model is simple 1 thermal zone building. And never ran successfully. Always show this message:
It says the error is "Null reference for setZoneforMasterThermostatLocation", but i couldn't find any clue where to input it in the VRFwithDOAS measure, anyone can help me with this?
can you add more details about your OpenStudio model. How many spaces are there? How many thermal zones? What thermostats have you set on the Thermal Zones?
Only a simple one room building. 1 space, 1 thermal zone, the thermostats I set in 24oc
