Re: [TRNSYS-users] Use of a varying boundary wall temperature profile - (Paul O Sullivan)



Title: Use of a varying boundary wall temperature profile - (Paul O Sullivan)
Paul,
  TRNBuild/Type56 will allow you to set the boundary temperature either as a "identical" or as a constant, an input, or a schedule. You want to select "userdefined" then click on the little arrow button to the left of the constant boundary temperature that pops up. Change from "constant" to "input." Go back to the Simulation Studio, right click on Type56 and tell it to update the input list. Once it does, you should see your the boundary temperature as an input. Read in your measured boundary temperature using type9 and pass the appropriate output to Type56.
Best,

Hi TRNSYS Users.

I am trying to establish if it is possible to use a measured temperature profile as the specified boundary condition for an internal boundary wall. I am measuring surface temperatures on both sides of the internal walls of the single room being used to validate a TRNSYS model. This means I could consider using this data as the boundary condition for these walls instead of modelling adjacent spaces to the room of interest. Does TRNBUILD only accept a single value for this condition or is there a way to apply a time varying boundary condition. Alternatively I can use an average over the period of analysis but this will give some inaccuracy to the model.

Thanks for your help. !
