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.
Dear TRNSYS users,
I am looking to simulate a reflector surface placed outside a building to direct solar radiation into a room through a window. My first objective is to model this reflection accurately, and the second is to determine the optimal angle for the reflective surface. Is it possible to achieve this in TRNSYS?
Thank you for your insights.
I was faced with a somewhat similar problem a few years back when modeling a reflector system that was trying to augment the amount of solar falling on a PV array. I'm not aware of any components that can do this in TRNSYS directly and I ended up using SolTrace ( https://www.nrel.gov/csp/soltrace.html) to characterize the radiation augmentation as a function of time in a data file that TRNSYS was then able to read. I essentially used SolTrace with the sun at various angles to generate a lot of values of my solar radiation multiplier. I used the general TRNSYS performance map data file format feeding solar altitude and azimuth into Type581 (although you may be able to use Type42 if you do not have the TESS Libraries) and getting back the interpolated value of the radiation multiplier.
kind regards,
David
