TRNSYS is a flexible graphically based software environment used
to simulate the behaviour of transient systems. TRNSYS is made-up
of two parts.
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. The kernel
also provides utilities that (among other things) determine
thermo physical
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 standard library includes
approximately150 models ranging from pumps to multizone buildings, wind
turbines to
electrolyzers, weather data processors to economics routines, and
basicHVAC equipment to cutting edge emerging technologies. Models are
constructed in such a way that users can modify existing components
or write their own, extending the capabilities of the environment.
