Welcome to the TRNSYS Users Forum.
The forum is a place where people can interact and have discussions about different topics involving the use of the TRNSYS software package. Here you can post topics for discussion or questions on using TRNSYS and get advice from other users or TRNSYS experts. This forum is not intended for detailed technical support. Users should contact their distributor’s hotline for such assistance.
Some tips for success on using the forum:
- Follow the Forum Rules posted in Forum Administration.
- There are categories for different types of topics and questions. Post your topic or question into the proper category.
- Before posting a topic or question search the existing topics (and the TRNSYS Users listserv archive or Post archive) to see if a similar topic or question has already been answered.
- Use a descriptive topic name. Don’t use attention getting subjects, they don’t get attention and only annoy people.
- State the version of TRNSYS and which add-ons your are using.
- Include enough specific details for your topic of question to be answered. Just posting “Why am I getting an error?” without describing the specific error and what you are trying to do when you get the error will not receive a response that fixes your issue.
- Remember when people help you, they are doing you a favor. Be patient, help people out by posting good descriptions of what you need help with, and be polite even if a response does not solve your issue.
- Moderators may edit your post for clarity or move your topic to a more appropriate category.
Hello,
I need some help about Trnsys 3D model to write my thesis.
I would like to model an air flow from a living room on the first floor to a room on the upper floor through a void.
The goal is to evacuate the overheating via windows that can open on the roof.
To do this, I used virtual surfaces but the air exchange between the different thermal zones is blocked.
Would you have a solution to simulate the air flow between two thermal zones according to the temperatures?
Thanks a lot,
Basile Colin student of the University of Liege.
The two options for having TRNSYS compute the flow between two air nodes are to implement either TRNFlow, which is a TRNSYS add-on that extends the TRNBuild interface to allow you to define the air flow connections between air nodes in your building or to use Type97, which is an implementation of a tool called CONTAM (freely available) that does basically the same.
I find that Type97 offers a little more flexibility and transparency but it requires that you use CONTAM's interface to redraw the building and there is a good bit of information redundancy. There is an example of using Type97 in .Trnsys18\Examples\
TRNFlow is perhaps a little less flexible in my experience but it uses the TRNBuild interface with which you are already familiar.
kind regards,
David
