TRNLIB - Libraries of User-Written Components for TRNSYS15As a service to the users of TRNSYS, the Solar Energy Laboratory maintains this collection of TRNSYS components voluntarily provided to us by TRNSYS users. One of the great features of TRNSYS is its modularity. Because of this feature, many TRNSYS users have written their own components. Many of these are good models that, with the thought of saving other users time and effort, they have been contributed to the TRNSYS library of components. The TRNSYS developers wish to express their thanks to the authors who decided to share their work with the TRNSYS community. TRNLIB is currently organized in several libraries:
TRNSYS 15 provides a link with EES as part of the standard library. The components here below add the ability to call other external programs, making TRNSYS even more flexible.
Type 62: Calling Excel This TRNSYS Type implements a link with Excel. The Fortran routine communicates with Excel through a Component Object Model (COM) interface, which allows a fast data transfer. TRNSYS sends the component's inputs to given cells in an excel worksheet. Excel then calculates the outputs using standard formulas or Visual Basic macros and sends them back to TRNSYS. The Type 62 manual and a description of the downloadable example are available online. Authors Jochen Wriske & Markus Oertker - Lehrstuhl für Technische Thermodynamik, RWTH Aachen Download
Type 155: Calling Matlab This TRNSYS Type implements a link with Matlab. The connection uses the
Matlab engine, which is launched as a separate
process. Authors Michaël Kummert - Solar Energy Lab, UW-Madison Comments and suggestions about Type155 should be sent to trnsys@engr.wisc.edu Download
HYDROGEMS is a
library of computer models for simulation of integrated hydrogen
systems based on renewable energy. Available components:
HYDROGEMS is a result of more than 7 years of modeling and simulation work performed at Institute for Energy Technology, Norway. The main sponsor of HYDROGEMS is the Research Council of Norway.
Several files are available for download:
Note: You may need to download the following (free) programs to open some of the files:

IEA / SHC Task 26 load profiles Ulrike Jordan and Klaus Vajen have developed a tool to generate realistic Domestic Hot Water (DHW) load profiles in the framework of IEA / SHC Task 26 (Solar Combisystems). Those load profiles have been used with TRNSYS for detailed simulations of Combisystems, and their authors have kindly accepted to share them with TRNSYS users.
For the latest information, please check the following website: http://www.solar.uni-kassel.de/ in the downloads section.
For more information, please check the following reference: "Influence Of The DHW Load Profile On The Fractional Energy Savings: A Case Study Of A Solar Combi-System With TRNSYS Simulations", Jordan U. and Vajen K., Solar energy, 69-6, 2001, pp. 197-208. An abstract is available on the TRNSYS website here.
The models in this library come from three main sources: the students at the Solar Energy Laboratory, the ASHRAE simulation toolkits, and various other individuals and groups of TRNSYS users. We are very thankful for any user or group that takes the time to send us their models. If you would like to become a contributor to the TRNSYS component library, please contact the TRNSYS Coordinator. There are three necessary items for adding your component to our library: a written description of the component, the FORTRAN source code, and sample input and output. We would prefer that you sent us (by mail or Email) the description and FORTRAN code as text files. Disclaimer: Because many of these components are not written in the Solar Energy Lab and have not been fully tested by the Solar Lab, we do not guarantee either the usability nor accuracy of the models as follows. Use these components at your own risk. Many of the problems with using components written by others comes from using the component outside of its intended range of parameters. Therefore we suggest that you check the component to make sure that it works in the range of values you are using. Available Component Types: |
