Non Standard Component Libraries

Through their work with TRNSYS, a number of groups have had the occasion to develop new components for TRNSYS and have made them available to other TRNSYS users. This page will familiarize you with the source and content of some of the more widely available libraries as well as providing links to pages where you can learn more.

TESS Component Libraries Through our consulting projects, TESS has developed well over 200 TRNSYS components. In 2001, we made an effort to select the best of those components, clean up, standardize and comment the source code, create both online and printed manual documentation, and make them into a commercially available product. An expanded second version of the libraries was released along with TRNSYS 16 in March 2003.

Transsolar Components TRANSSOLAR GmBH, the German TRNSYS developer, also does a great deal of consulting work with TRNSYS. They sell fully documented components individually and in groups

STEC Library STEC is a collection of TRNSYS models especially developed to simulate solar thermal power generation. It is a supplement to the standard TRNSYS routines featuring components from solar thermal power plants like concentrating collectors, steam cycles, gas turbines and high temperature thermal storage systems. It was developed as a SolarPACES activity and is steadily used, updated and completed by users within the SolarPACES group. The STEC simulation models are intensively used in feasibility studies for solar thermal power projects as well as in research programmes for new solar thermal power technologies.

TRNLIB From time to time, TRNSYS users have been kind enough to send us components that they have developed. The Solar Energy Laboratory maintains an online resource of these components for free download. We can unfortunately not guarantee the correctness of these models but we have gone ensured that they will compile in the TRNSYS environment.
