[TRNSYS-users] U values

[Arne Hübner <arne.nils.huebner@gmail.com>]

Hello TRNSYS-Users,

does anybody know, how TRNSYS calculates the U-values? Cause when I calculate the U-values by Hand with that Formula:

 

U = 1/(Rsi+d/Lambda+Rse)

 

Rsi,horizontal = 0,13 m²*K/W

Rse,horizontal = 0,04 m²*K/W

 

I get different U-values.

Which heat Transfer coefficients does TRNSYS use?

 

Kind regards,

 

Arne Hübner
