[esp-r] Re: simulating VDI 6020

[Achim Geissler]

Dear Adhi

 

allthough I do not know what the Example 1 in VDI 6020 covers, the results
you sent give rise to following questions for me:

1)      How long was your “warm up” for ESP-r?

2)      Is Example 1 not a “jump response” type of test? The 6020 plot seems
to imply this

 

In any case, an old “Bine” information (III/99) covers VDI 6020 in its
development stage and also compares ESP-r results (among others). Here,
“Example 1” shows good agreement.

Subject: [esp-r] simulating VDI 6020

 

Hello,
I did simulation VDI 6020 (Example 1) with ESP-r. It is not clear what
weather data is used in that test. My friend said, it is TRY for Wuerzburg
(weather region 5). I built the model and used this weather data, but the
results are different. Same trend but not close (see VDI6020.jpg). My
question is: is that the correct weather data for VDI 6020 test? if yes, why
is so much different between VDI's results and ESP-r's results? I have
checked construction and schedule of my model are according to VDI 6020
(Example 1). Thank you for your help.

regards
Adhi
