I am trying to find the effect of surface emissivity of long wave radiation on cooling load and surface temperature.
So I built a simple box, and set the solar absorptance 0.9
I test the cases: thermal emissivity 0.1 and 0.9, (for exterior surface only)
the result is very strange: no difference... both for cooling load and surface temprerature..
what kind of data can i check?
I have run those for V2-2 and V3-0, same results...
Thanks and regards
