Revision history [back]

I’m applying the VRFwithDOAS measure (available on BCL: https://bcl.nrel.gov/node/82300) to the DOE OfficeSmall prototype model and I am wanting to have the measure set some of the indoor unit fan parameters (at least the Pressure Rise). When I run the measure, it appears to be setting the indoor unit fan parameters to match the OS:Fan:OnOff defaults defined in my hvac_library.osm file.

I don’t understand how the measure.rb file for this measure is defining these fan parameters; I think it is calling the OsLib_HVAC.rb file to do so but in that script I don’t see any if case for when “zoneHVAC” == “VRF”. How can I modify the VRFwithDOAS measure to set these fan parameters? I'm most interested in having it set the Pressure Rise to be something lower than the 300 default defined in my hvac_library.osm file (probably closer to 125).
