Re: [TRNSYS-users] Forrtl: severe (38): error during write, unit 44, file SUMMARY.BAL

Dear all,

Good day!

I met an error "Forrtl: severe (38): error during write, unit 44, file SUMMARY.BAL", which was attached by a file.

Did you meet this problem? How could you deal with it?

Many thanks in advance!

Br.

Subject: [TRNSYS-users] Where can I find some example to couple the Type56 Multizone and Type101 Fluent?

Hello,

I'm doing some research on the coupling of Trnsys(TYPE56 Multizone) and CFD program recently. The most referenced work is the doctoral thesis of Z. Zhai, “Developing an integrated building design tool by coupling building energy simulation and computational fluid dynamics programs,” Thesis, Massachusetts Institute of Technology, 2003. http://dspace.mit.edu/handle/1721.1/17617

And I see there is also a Type101 in TRNSYS for calling Fulent, so I tried to find more information about it, the only thing I found is a paper from Diego A. Arias http://www.ibpsa.us/pub/simbuild2006/papers/SB06_231_237.pdf. In the paper Multizone is unfortunately not involved. I hope I can get more information from you here.

According to the work of Zhai, the convective heat transfer from wall surface to air is the key of the coupling process. My Question is, How can I implement the convective heat flux to TRNSYS?

Best regards!

Yi

Eric,
The tutorial that I mentioned last week is exactly what you are asking for. It shows how to connect controller Types and equipment Types to a Type56 building simulation. The tutorial (called "temperature level control from energy rate control") can be downloaded from:

http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm

Regards,
David

David,
Thanks for your answer, it helped me a lot. But what I really wanted to
know is:
How is the Type 987 and Type 600 tied together with a building project
with a controller?
please please how me an example.

Kind regards,
Eric

Eric,

I would recommend that you go through the tutorial called "temperature
level control from energy rate control" that is available for download
from
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm

It describes the process of migrating from using Type56 to compute
heating and cooling loads to using controllers and equipment models to
condition the space.
Kind regards,
David

hello users,

ich möchte ein Hotelzimmer (Building-Projekt) mit Fan Coil (Type 987
oder
Type 600) simulieren. Man muss dabei ein richtiger Regler auswählen,
sonst
macht die Simulation kein Sinn. Ich habe dabei alles versucht, aber ich
kann das nicht zum laufen bringen. Bitte kann mir jemand ein Beispiel
schicken? So kann ich sehen wie die Verbindungen gemacht wurde.

Thanks for any help.
