2016-08-24 13:54:03 -0500 commented question VRF with DOAS Measure Error from BCL

I went through the model and I have 22 thermal zones assigned to 22 spaces on 7 floors.

Is the measure looking for a master zone for each VRF system? Is that something I can assign prior to running the measure?

2016-08-17 10:09:50 -0500 asked a question VRF with DOAS Measure Error from BCL

Got the following error while trying to run the measure:

/ApplyMeasureNow/UserScript/resources/OsLib_HVAC.rb:1181:in `setZoneforMasterThermostatLocation': invalid null reference Expected argument 1 of type openstudio::model::ThermalZone const &, but got NilClass nil (ArgumentError)

in SWIG method 'setZoneforMasterThermostatLocation'

Followed the instructions from this page: https://unmethours.com/question/18233... "Error Applying BCL VRF w/ DOAS Measure"

But still got the same error above.

Can't seem to resolve after deleting the existing HVAC system entirely.

Any help would be appreciated

I couldn't figure out how to tie my air loop or water loop to my existing chilled water loop or hot water loop and I can't find any tutorials. I was assuming that OpenStudio automatically connected the unit to my existing hot water loop.

Thanks!

Hey All,

New openstudio user here, and I'm trying to make my first simulation, however I keep getting the same error.

On more then one occasion I keep getting this same error for all of my heating coils:

* Severe * IP: IDF line~912 Error detected in Object=COIL:HEATING:WATER, name=UNIT HEATER HW HTG COIL 10 * ~~~ * Field [Water Inlet Node Name] is required but was blank *** IDF Context for following error/warning message: *** Note -- lines truncated at 300 characters, if necessary... *** 907 Coil:Heating:Water, *** indicated Name=Unit Heater HW Htg Coil 10 *** Only last 6 lines before error line shown..... *** 908 Unit Heater HW Htg Coil 10, !- Name *** 909 Always On Discrete 1, !- Availability Schedule Name *** 910 Autosize, !- U-Factor Times Area Value {W/K} *** 911 Autosize, !- Maximum Water Flow Rate {m3/s} *** 912 , !- Water Inlet Node Name *** 913 , !- Water Outlet Node Name

How can I map the node names correctly so I can run my model?

Thanks.
