– AIRFLOW SIMULATION IN BUILDINGS
TRNSYS thermal mutlizone
building model, type 56, requires air flows between zones as input
values. However, in natural ventilation systems these depend on the
wind pressures and the inside and outside temperatures. To account for
this situation, a coupling with an air flow model is absolutely
TRNFLOW integrates the multi-zone air flow model COMIS into the type
56. An internal solver, optimized for this task, iterates in
each time step between the two models until their solutions are
consistent. The existing GUI TRNBuild was extended in such a way that
data for the air flow model can be entered. Thus a user-friendly
handling of the coupling is assured. With TRNFLOW, a immense step
forward has been made for building simulation with TRNSYS.

Thermal Energy System
Specialists (TESS) of Madison, Wisconsin
has developed new component libraries for the popular TRNSYS
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 Simulation Studio 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
projects that demonstrate typical uses of the
component models found in that library. TESS currently has fourteen
component libraries for sale.

Software Based on TRNSYS
TESS TRNSED Software
Thermal Energy System Specialists (TESS) uses a tool of the TRNSYS package called TRNSED to create stand-alone TRNSYS based applications for end-users that are not TRNSYS savvy. These TRNSED applications hide the fine details of the TRNSYS simulations to display only the relevant information to the end-user in a similar fashion of a website. All TRNSYS users have the ability to also create these applications with the TRNEdit tool in the TRNSYS package.

interface for quick and easy simulations of thermal solar energy
systems. Based on TRNSYS, it is intended to be used
for sizing the required equipment for a solar domestic hot water systems. It is possible to create up to 138 different configurations.

TRNSYS FMU Export Utility
The TRNSYS FMU Export Utility is an openly available stand-alone tool for exporting FMUs for Co-Simulation from TRNSYS 17 models. Among other things, this tool allows to link TRNSYS 17 at runtime with Modelica or Simulink models. The tool supports FMI version 1.0 and 2.0 and provides a graphical user interface for generating FMUs for Co-Simulation.

NIST TRNSYS/Java coupler
Type277 utilizes socket communication to provide loosely-coupled integration between TRNSYS and Java-based components. Bi-directional flow of information is facilitated using the client-server architecture of Java. Type277 is compiled as both a 32-bit and 64-bit dynamic link library to support co-simulation with TRNSYS17 and TRNSYS18 projects. An application of Type277 is demonstrated by modifying an example TRNSYS project.
The Java project and files, TRNSYS modified example projects, and Type277 dynamic link libraries can be downloaded from the NIST GitHub site: https://github.com/usnistgov/JTRNSYS.git
