[TRNSYS-users] Parameters of Type 460

[David Bradley]

Yves,
  I believe that the hypocaust is able to travel under 6 different 
surfaces (perhaps 6 different building zones or perhaps ambient, then 
some building zones...) The parameters and related inputs indicate how 
the model should handle the energy balance at the surface. For each of 
the 6 surface types, you have the choice of specifying 0 : corresponding 
input Xsurf is surface temperature, output Xbord is inflowing energy 
rate or 1 : corresponding input Xsurf is is inflowing energy rate, 
output Xbord is equivalent border temperature. Even in situations where 
my hypocaust traveled only under a single surface, I specified values of 
the parameters for all 6 surfaces because it looked to me from the code 
as though it would not be a good idea to try and just specify those that 
I needed.
Kind regards,
 David
