Re: [TRNSYS-users] Future Weather file Simulation
Shameem,
I don't think that the weather file is entirely at fault. Certainly the
weather conditions are what causes the problem but more likely, it is
the window data that causes the problem. the first thing to try is to
make sure that not only is the internal convection coefficient set to 11
kJ/h.m2 but that the external convection coefficient is also a constant
(64 kJ/h.m2 perhaps). If that does not solve the problem, use Window5 to
see if you can adjust the window properties slightly, put the new
results into your *.b17 (or *.bui file if you are using Trnsys16) and rerun.
Kind regards,
David

Hi,
I am trying to simulate future design summer year (DSY) weather files for the
year 2050 and 2080 medium emission scenario from the UKCP09 on TRNSYS. And my
location is London Heathrow. I got the weather files from:
http://centres.exeter.ac.uk/cee/prometheus/downloads.html
When i try to simulate the 2050 DSY future weather file, it only works for
2881-8760 hours, whereas for 0-2880 hours it says there are errors. for example:
zone 1 surface 5 pane temperature calculation id diverging at time 331TDIF:
0.00658 ITPANE : 31 ITCALC : 51
The heat transfer coefficient is 11 on the window manager though.
I really need your help.
Thank you for your kind consideration.
Shameem
