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.

ground reflected radiation with type 67

Hello 

I am wandering how to treat ground radiation with type 67. In the example given, the type 71 does not use ground radiation but if I use type 1346, should I estimate the total radiation as : 

I_total_shaded = I_beam_shaded + I_sky_diff_shaded  + I_ground_not_shaded 

and connect I_beam_shaded to input beam radiation of the collector, I_sky_diff_shaded to input sky diff radiation and I_ground_not_shaded to input  ground radiation or is it better to: 

- connect the total diffuse radiation ( sky+ground) to input diffuse radiation of type 67 and connect I_diff_shade to sky diff radiation of the collector and put 0 as input ground radiation of the collector ? 

 

Thanck you very much 

Louis
