[EnergyPlus_Support] Re: EnergyPlus Model: Hydronic low temperature radiant system?


Look up the Low Temp Radiant object in the excel sheet that is located in the documents/examples folder. It will point you to which example files use this.

Pricipally it's easy to set up. But I find it a major work flow problem, because my geometery generation program (Design Builder) does not support radiant floors/ceilings. After exporting geometery, I have to make adjustments to Plant, Zone Equipment, Constructions and assign those constructions into the relevant BuildingDetailed objects.

If I then have to make a geometery change in DB, the whole process starts over. If I have more than 7 Zones, this absolutely kills me!

It also does't report nicely in the AllSummary report.

What we need here is a Template that will work something like a negative ProcessLoad object that can be sized, controlled and coupled to the PlantLoop and report as a HVAC equipment. (perhaps without building it into a construction) These radiant panals are zone HVAC. We are not always dealing with "Betonkernaktivierung" or Activated Concrete Cores.
