BREVE DESCRIPCIÓN


TRNSYS se utiliza principalmente por ingenieros, arquitectos y consultores energéticos para diseñar y optimizar sistemas (enfoque en energías renovables y sistemas eficientes) y en el diseño de edificios de bajo consumo de energía.

TRNSYS se compone de dos partes. La primera es un motor (llamado kernel) que lee y procesa el archivo de entrada, resuelve iterativamente el sistema, determina la convergencia y traza las variables del sistema. El kernel también proporciona utilidades que, entre otras cosas, determinan propiedades termofísicas, invierten matrices, realizan regresiones lineales e interpolan archivos de datos externos.

La segunda parte de TRNSYS es una extensa biblioteca de componentes, cada uno de los cuales modela el rendimiento de una parte del sistema. La biblioteca estándar incluye aproximadamente 150 modelos que van desde bombas a edificios multizona, turbinas eólicas a electrolizadores, procesadores de datos meteorológicos a rutinas económicas y equipos HVAC básicos a tecnologías emergentes de vanguardia. Los modelos se construyen de tal manera que los usuarios pueden modificar los componentes existentes o escribir los suyos propios, ampliando las capacidades del entorno.

Después de 35 años de disponibilidad comercial, TRNSYS sigue siendo un paquete de software flexible basado en componentes que se adapta a las necesidades siempre cambiantes de los investigadores y profesionales de la comunidad de simulación energética.

EXTENSAS LIBRERIAS


TRNSYS incluye bibliotecas estándar con muchos de los componentes que se encuentran comúnmente en los sistemas de energía de edificios, así como rutinas para manejar datos meteorológicos, procesamiento de radiación solar, equipos HVAC básicos, celdas de combustible de hidrógeno, tecnologías eléctricas y térmicas solares, almacenamiento térmico, acoplamiento a otras herramientas de simulación. y procesamiento de resultados de simulación.

Aunque TRNSYS incluye la Biblioteca estándar para los sistemas de energía más comunes, incluye un método para agregar nuevos módulos, lo que permite a los usuarios modificar o crear fácilmente nuevos componentes para tecnologías que no están cubiertas.

Además de la biblioteca estándar incluida en TRNSYS, los usuarios pueden comprar bibliotecas TESS que incluyen más de 250 componentes. Cada una de las bibliotecas de componentes viene con un archivo de modelo TRNSYS (*.tmf) para usar en la interfaz de Simulation Studio, el código fuente y un proyecto TRNSYS de ejemplo (*.tpf) que demuestra los usos típicos de los modelos de componentes que se encuentran en esa biblioteca.

Las bibliotecas TESS representan lo mejor de los tipos internos en TESS (Especialistas en sistemas de energía térmica).

SISTEMA OPERATIVO

TRNSYS requiere Windows 95/98, NT 4.0, 2000, ME, Windows XP, Vista, Windows 7, Windows 8 o Windows 10

COMPILADORES

Gracias a la tecnología drop-in DLL, no se requiere un compilador para agregar componentes a TRNSYS si los obtiene como una DLL precompilada.
Si desea depurar TRNSYS o agregar componentes para los que recibió el código Fortran, necesitará un compilador Fortran (consulte la Guía del programador para conocer los compiladores compatibles). Si desea crear sus propios componentes, necesitará un compilador capaz de crear una DLL. Esto incluye cualquier compilador reciente compatible con Windows para C++, Delphi, Fortran u otros lenguajes.

Bugfix: corrected an error in the number of data items included in the Type190.dat example inverter data file.
Bugfix: the pv_ref_params.exe tool for generating parameters for the 5-parameter PV model (Type190) had expired and has been renewed.
Enhancement: Type190 outputs power in both W and kJ/h. The description of each output in the proformas now makes the units clear. Previously there was no way to tell the two outputs apart.
Enhancement: Simulation Studio documentation updated.

TRNSYS Components

Bugfix: replaced the Type169debug.dll with the release version. The debug version of the dll was causing a Visual Studio environment crash when debugging a *.dck.
Bugfix: corrected a bug in Type47 that allowed the battery SOC to continue decreasing after discharge has stopped or to continue increasing after charging had stopeed.
Bugfix: corrected a bug that prevented the CoolProp routine from working for all fluids.
Bugfix: the v18.2 change to always rereading parameters whether or not the unit number has changed caused a problem since we were using the «»it’s time to reread parameters»» section to generate an error that only one instance of Type49 is allowed per simulation. Fixed it by storing the original unit number and comparing that to the current unit number on reread parameters. If they’re different then we error out.
Bugfix: the file Type169debug.dll caused a Visual Studio crash when debugging a simulation from the compiler. The file was replaced with the release version.
Bugfix: the getTimeStepNumber() access function no longer returns a random integer close to the present time step number but actually returns the present time step number.
Enhancement: the getParameterOfUnit() access function has been added. It returns the ith parameter of unit j.
Enhancement: the getNumberOfUnitsInDeck() access function has been added. It returns the number of UNITS in the present dck.
Enhancement: the getTypeNumberOfUnit() access function has been added. It return the TYPE number associated with a specified UNIT number.
Enhancement: added access functions to the kernel to tell a Type how many instances of that TYPE number are used in the simulation, and which instance (of the same Type) a particular UNIT is. So by calling these access functions a unit can know “there are 3 instances of this type in the simulation and the current unit is the 2nd instance in the deck”. This helps manage storage for Types that must store a large amount of data and cannot use the storage array (or prefer not to).
Enhancement: added a “ShowMessage” for Messages – it finds unit and type no by itself, and the error code is optional. The intent was to provide a more intuitive (and shorter) way to print messages.
Bugfix: The functions GEWARN, NEWARN, and EQWARN generated an error even when the «generate warning» option was selected.
Bugfix: the GTWARN function could sometimes generate a -99999 value.
Bugfix: Type119 – the total air flow rate parameter was incorrectly forced to be greater than 0.
Bugfix: Type126 (simple cooling tower) generated a floating point error if the natural convection airflow or capacity parameters were set to zero.

TRNBuild – User interface of the multizone building model

TRNSYS Components

Bugfix: corrected a bug in Proc.f90. When writing const and var to the *.lst file, we are only writing the first 10 characters of the array, not all the way out to the end of maxEquationLength. This can cause stray letters and partial variable names to be written to the lst file.
Bugfix: added code to avoid a division by zero in the RelativeHumidity() function in the psychrometrics routine.
Bugfix: fixed a bug in which in some rare circumstances Types could claim that they accessed an input value higher than the range they had reserved. NOTE: this change means that all Types reread the values of their parameters once per timestep. Parameters are reread from the values stored in the kernel. They are not reevaluated.
Bugfix: Type158 now does its adiabatic mixing after energy balances are computed but before outputs are set.
Bugfix: fixed a case in Type162 in which high air flow rates and low water flow rates caused a floating point error.
Bugfix: corrected a bug in Type103 that caused the cell temperature to be overestimated and therefore the power to be underestimated.

Package

The C++ Type template and TRNSYS.h header file are updated for the v17 calling standard.

TRNSYS Executable and Online Plotter

The online plotter was displaying different results when refreshing the plot window. (This did not effect actual simulation results.)
The command line options /n and /h both suppress the TRNSYS error dialog window.

Bugfix to online license activation

TRNSYS Components

Using multiple Type15s in a single project with weather files from different time zones produced incorrect solar radiation values.
Type97 (CONTAM) did not check to make sure that all zone volumes are non zero.
The three letter unit codes were incorrect for Type162 inputs 6 and 7.
A new component for calling a Python script is included. Type169 calls the script directly and does not use a transfer data file as Type163 does.
