TRNSYS primary

Each physical piece of thermodynamic equipment is modelled in TRNSYS with a component. Each component is really a FORTRAN source code model. With TRNSYS, a large number of components are available. The Standard Components include are:

Standard TRNSYS Components (shipped with TRNSYS)

Standard Format User Format

Many individuals have written TRNSYS components and given the Solar Lab permission to share these components with other TRNSYS users. The source code and description of these components has been placed online. These free components are available for TRNSYS 16 and TRNSYS 15

While TRNSYS comes with a set of standard components, two of the TRNSYS distributors (Transsolar and TESS) have also had occasion to create new components in the course of their work using TRNSYS. These distributors have been kind enough to package their components so that other users can benefit from them. The SEL distributes some of these libraries. Please download an order form or contact the TRNSYS coordinator for more information.

Transsolar sells a variety of non-standard types and TRNSYS add-ons like TRNSYSLite. Contact them at hotline@transsolar.com for more information. The components currently sold by Transsolar are:

Thermal Energy System Specialists (TESS) of Madison, Wisconsin has developed new component libraries for the popular TRNSYS 15.1 simulation software. Each of the components in these new libraries has been extensively tested and comes complete with on-line documentation, source code, and free technical support for 1 year from the date of purchase. Each of these libraries comes in the IISiBat front-end format for TRNSYS (source code, documentation, on-line help, icon, etc.) The source code is provided for each of these models so that they can be quickly and easily modified if the user wishes to make changes to the model. Each of the component libraries comes with one or more sample IISiBat/TRNSYS projects that demonstrate typical uses of the component models found in that library. TESS currently has six component libraries for sale; a solar component library, a storage tank component library, an HVAC component library, a geothermal heat pump component library, a utility component library, and an application component library. A list of the components found in each library is included below. Please check the TESS website for more details.

If you have purchased any of the TESS Component Libraries, check the TESS website frequently to make sure that you have the very latest versions. Bug fixes and upgrades to the current version are free of charge to registered users. Call, e-mail, or fax a request for the upgrade. Announcements about bug fixes and upgrades also occur via the TESS Library mailing list.

You can also contact TESS if you are looking for a particular component that is not listed here.
