Active layer in wall

asked 5 years ago

Is it possible to create an active layer inside a wall, like in TRNSYS? In TRNSYS you just specify some parameters like:

  • specific heat coefficient of water
  • pipe spacing (center to center)
  • pipe outside diameter
  • pipe wallthickness
  • pipe wall conductivity

What tool are you using? There is likely a tag that you can add for the tool so that others can give better guidance.

I am using the IDF Editor

It sounds like you are trying to use EnergyPlus. You will have to create your wall construction and specify the parameters for a Construction:InternalSource. Assign the construction you just created to the wall surfaces as required, and then add a ZoneHVAC:LowTemperatureRadiant:VariableFlow or ZoneHVAC:LowTemperatureRadiant:ConstantFlow to the zone where your building is. You can look at an example set-up in the EnergyPlus example files.

Means I create my wall in "Construction:InternalSource" and add a "ZoneHVAC:LowTemperatureRadiant:ConstantFlow" to the zone and to the surface?

And do you know how I can create an surface list in the IDF Editor? Cause I have a lot of surfaces, where I have to add the LowTemperatureRadiant system. It would take long if I have to create for each surface a new ZoneHVAC:LowTemperatureRadiant:ConstantFlow - system.

You add the ZoneHVAC to the zone. And yes, you actually need to specify a ZoneHVAC:LowTemperatureRadiant:SurfaceGroup to the ZoneHVAC if all the surfaces work in paralell. That item is available on the IDF editor.
