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) 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.
I am simulating a novel solar Fresnel collector that has double axis tracking features. I am using for that the linear Fresnel (type 1288). I am trying to find a way to enable double tracking for this type. Is it possible to consider single tracking or double tracking for this type?
One of the solutions I tried is setting the collectors azimuth equal to 90 degrees plus the sun’s azimuthal angle and it seems to improve the performance.
Any thoughts will be really helpful
Hadi,
Type1288 takes the incident solar radiation as well as the beam radiation incidence angle, the collector slope and azimuth as inputs. That means that any tracking scheme can be calculated upstream of the collector model. You'll define the slope and azimuth of your collector's axes in the weather data reading/processing component (usually Type15) and then select the appropriate tracking mode for that surface. Type15 does all the calculations of incident radiation on the tracking surface and you just pass them from Type15 to Type1288.
kind regards,
David
