Jens : I’m not sure
it’s about “thermal resistance” … but more about “radiative
screen”
Valérie : I don’t
know how to take that in account in type 56 … but maybe you can directly
modify the sky temperature in studio ?
If you find a solution, I’ll
be interesting!

Blinders for long-wave radiative exchange
Valérie,
In TRNbuild in the Window Type Manager you can
specify “Additional Thermal Resistance” of Shading Devices. I never
used that but it might be a solution.

Subject: [TRNSYS-users] Blinders
for long-wave radiative exchange
Dear Trnsys users
I would like to estimate the impact of the glass emissivity of windows
fitted with blinders (only during the night). However, making the simulation
and reading the type 56 user's manual, I realized that external and internal
shading devices (blinders) only reduce incoming solar radiation.
So my question is: is there a way to simulate night blinders, that is
to say blinders that reduce long-wave radiative exchange with the fictive sky
temperature?
Best regards and Thanks a lot.
