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.

@a_weiss @tm-abir-ashan I'm going to split this into two replys so that we can keep the threads separate. This is a reply about the procedure for sol...
In our case the heat pump capacity was 240kW and its COP at the entering condition was 1.6. Those two values basically didn't vary but only because we...
@tm-abir-ahsan If a differential equation can be written in the form dX/dt = Ax+B where A and B are constant over the dt interval then there is a qu...
Virk, Most of the heat pump models in Trnsys use performance maps meaning that they read heat pump capacity and power consumption from an external...
