[TRNSYS-users] Variable global thermal conductivity

[David BRADLEY]

Denis,
Type56 allows you to set the outside convection coefficient of a surface 
(walls, ceilings, etc.) as a constant value, as a scheduled value, or as 
an input to Type56. If you select "input" then you can choose whatever 
algorithm you want for the external convection from your roof. The 
physical properties of the material in the roof (density, thermal 
conductivity, and specific heat) are then constant but the convection on 
the outside (and inside if you wish) surfaces vary with external conditions.
Kind regards,
David
