[TRNSYS-users] TRNSYS-users Digest, Vol 62, Issue 26

[ghetu mariana]

Hello,
 
I’m having a problem with TrnBuild. I’m trying to describe
an office tower in TrnBuild and it keeps sending error messages that either the
timebase is too small (it’s set for 1 hour, the default value) or that the
capacity of a wall is too small. Thing is the wall type creating the error is
just fine, its capacity is good. After I fix one wall type I get an error
message for a different wall type. I don’t know where all this is coming from.
 
By the way, there’s an error in type52 code. The computation
of the convection coefficient for water inside the tubes of the cooling coil
for laminar flow is done considering Nu=4.36. It might be a simplification but
it’s not ok.
 
Best regards,
