[TRNSYS-users] Adding a water layer for cooling the roof

[David Bradley]

Artemi,
  I would think that your approach of writing an external model that 
couples with Type56 in order to assess the impact of your wetted roof is 
the correct one. I would imagine that the model would couple to the 
building using a BOUNRARY wall much like the user-written Type204 phase 
change material wall or the TESS Library Ground Coupling components do. 
I am not aware of any way to use standard components to model the 
evaporatively cooled roof and couple it to the building.

  I am also not aware of whether anyone has tried running TRNSYS on 
Windows 7. I am personally waiting for Windows 7 to be out for at least 
3 months before I try it!!
Kind regards,
 david
