– 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 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.

Software Based on TRNSYS
System Advisor Module (SAM)
The National Renewable Energy Laboratory (NREL) uses the TRNSYS engine for residential to utility scale solar applications in their System Advisor Module program. SAM considers not only includes many different technologies but also includes cost benchmarking, market penetration analysis, and other relevant considerations.

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.
