It has a number of improvements to the graphical user interface that were found to be very useful.
#TRNSYS OUTPUT ELEMENTS UPDATE#
Models are constructed in such a way that users can modify existing components or write their own, extending the capabilities of the environment.Īfter 35 years of commercial availability, TRNSYS continues to be a flexible, component-based software package that accommodates the ever-changing needs of both researchers and practitioners in the energy simulation community. The latest update of TRNSYS, Version 15, was used for this work. The standard library includes approximately 150 models ranging from pumps to multizone buildings, wind turbines to electrolyzers, weather data processors to economics routines, and basic HVAC equipment to cutting edge emerging technologies.
as well as other elements that the user should take into consideration when using the model (e.g. routine so that the kernel can check the user s input/output connections. TRNSYS 17 a TRaNsient SYstem Simulation program Volume 4 Mathematical Reference. The second part of TRNSYS is an extensive library of components, each of which models the performance of one part of the system. TRNSYS users will be familiar with the idea that TRNSYS components are all. The kernel also provides utilities that (among other things) determine thermophysical properties, invert matrices, perform linear regressions, and interpolate external data files. In this study, the WHR model was developed using the format of standard components in TRNSYS 17 which consist of inputs, constant parameters and outputs.
The first is an engine (called the kernel) that reads and processes the input file, iteratively solves the system, determines convergence, and plots system variables. While the vast majority of simulations are focused on assessing the performance of thermal and electrical energy systems, TRNSYS can equally well be used to model other dynamic systems such as traffic flow, or biological processes. TRNSYS (pronounced 'tran-sis') is an extremely flexible graphically based software environment used to simulate the behavior of transient systems.
