Hello,
I’m trying to understand how trnsys deals with
long-wave radiation. I know that trnsys calculates it with the star network
method from Seem (adjusted by Koschenz in 1997). I looked at the method and I
wonder how the absorption factor between surfaces is determined. Seem refers to
Gebhart, but this method uses view-factors and trnsys doesn’t know them. So
how does trnsys determine this absorption factor?
I also wonder if it is possible to adjust (or make
variable) the mean average wall temperature (used to linearize the long-wave
radiation exchange between surfaces between zones). In my project I have one
wall which probably is a lot warmer than the other walls.
Met vriendelijke groet,
Mariëlle Nuchelmans
