[TRNSYS-users] Type 56 radiation with wall type "Boundary"

[Christian Herløv Krintel <s103618@student.dtu.dk>]

Hi all,
I am trying to model a small 0.5 m cubicle test cell with opaque walls, 
placed inside a climate chamber with a step increase of the air 
temperature.
I use Type 56 with all six walls with wall type "Boundary" and the 
temperature step function as the boundary. However the air temperature 
of the test cell increases at a slower rate than from the experiment, 
and I wonder if longwave radiation from the external cubicle walls to 
the walls of the climate chamber somehow can be included in the 
simulations?

Best regards
