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,
type 5a has a small problem in the input data. If your "Source side inlet temperature" temperature is equal to 20 Celsius OR 20 Kelvin, THE RESULTS will be the same. In other words, "Unit conversion" does not work properly.

In TRNSYS18, there is pop-up notification that reads, "WARNING: Changing an input unit will not affect the value calculated by any variables connected to this input. Only the constant initial value will be converted." In other words, if the input is connected to the output of an equation block or any other component, the input's units will be the default units for that input in the proforma, not the chosen units. This is true for all TRNSYS Types, not just Type 5a.

The same behavior was true in TRNSYS17 and all earlier versions of TRNSYS, the automatic pop-up notification was added with TRNSYS18 to make the behavior more explicitly clear.
