Re: [TRNSYS-users] u-value of a wall : which Ntype?



Eleni,
 It is not exactly correct because it is not time dependent and uses default interior and exterior convective coefficients but I usually use the u-value shown in the *.inf file as my reported u-value for walls. I do not think that there is a special ntype for the u-value of walls. Please someone correct me if I am wrong about that!!

 As for NTYPE86, it is the equivalent thermal resistance (r-value) between a given (user specified) surface and the star-node (for radiation exchange calculations).

Kind regards,
 David
