Thestandard library includes approximately 150 models ranging frompumps to multizone buildings, wind turbines to electrolyzers,weather data processors to economics routines, and basic HVACequipment to cutting edge emerging technologies. The kernel also provides utilities that (among otherthings) determine thermophysical properties, invert matrices,perform linear regressions, and interpolate external data files.The second part of TRNSYS is an extensive library of components,each of which models the performance of one part of the system. The first is an engine (calledthe kernel) that reads and processes the input file, iterativelysolves the system, determines convergence, and plots systemvariables. While the vast majority ofsimulations are focused on assessing the performance of thermal andelectrical energy systems, TRNSYS can equally well be used to modelother dynamic systems such as traffic flow, or biologicalprocesses. TRNSYS (pronounced ‘tran-sis’) is an extremelyflexible graphically based software environment used to simulatethe behavior of transient systems.
