TRNFlow – 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 necessary.

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.

TESS-Libraries

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.
